Abbreviations, Definitions and Symbols

The following abbreviations, terms and acronyms are used throughout this manual:
AED Automated External Defibrillator
AAMI American Association of Medical Instrumentation
Arrhythmia An abnormal rhythm of the cardiac muscle; an abnormal

pattern or rate of heart beats.
AutoSequence A series of measurements or test operations that are run
automatically in a predefined order, with or without user
involvement.
BPM (ECG) Beats Per Minute
Cardioversion A medical procedure in which an electrical discharge is

applied to a patient to correct a cardiac arrhythmia,
specifically tachycardia or atrial fibrillation. The procedure
requires a defibrillator which can be set to synchronize its
discharge to the electrocardiogram.
Clip Record Temporary (volatile) memory where device information and

test data is accumulated, until the data is saved as a Test
Record.
Defib A defibrillator; or, the act of defibrillating.
Demand Mode In reference to pacemakers, a mode of operation in which

the pacemaker is responsive to an ECG input signal. Also
referred to as "synchronous mode". When operating in
demand mode, the pacemaker generates pacing pulses in
the absence of ECG activity.
DUT Defibrillator Under Test, or Device Under Test
ECG Electrocardiogram. Equivalent to EKG.
Hz Hertz
IEC International Electrotechnical Commission
LA Left arm ECG lead
LL Left leg ECG lead
Definitions # Page xi
Non-Demand Mode In reference to pacemakers, a mode of operation in which

the pacemaker is not responsive to an ECG input signal.
Also referred to as "asynchronous mode". When operating
in non-demand mode, the pacemaker generates pacing
pulses regardless of whether there is ECG activity or not.
Paced Refractory Period Immediately after generation of a pacing pulse, paced
refractory period (PRP) is the time interval over which the
pacemaker remains insensitive to the ECG. If a QRS
occurs within the PRP following output of a pacing pulse,
the pacemaker ignores this QRS.
Pacer A transcutaneous pacemaker
PPM (Pacemaker) Pulses Per Minute
QRS complex A specific segment of the electrocardiogram signal,

comprising the Q, R and S waves, which corresponds to
the heart systole.
RA Right arm ECG lead
RL Right leg ECG lead
Refractory Period When a pacemaker is operating in synchronous or

demand mode, the refractory period is the time interval
during which the pacemaker is insensitive to an ECG input
signal, and in particular, the QRS complex of the ECG.
Sensed Refractory Period The time interval after a detected QRS during which a
pacemaker remains insensitive to the ECG. If a QRS
occurs within the refractory period following a detected
QRS, the pacemaker then ignores this second QRS.
Test Record Test result data which has been saved to the non-volatile
Data Log as a record of all tests performed on a particular
defibrillator or pacemaker, as identified by I.D. or control
number. A Test Record may be recalled from the Data Log
for viewing on the LCD or printing. Test Records can be
downloaded in bulk to a PC using Phase3pc software.
Transcutaneous Pacemaker A pacemaker which stimulates cardiac muscle via
electrodes applied to the outside of the body, usually the
chest. Many defibrillators incorporate a transcutaneous
pacemaker.
V1-V6 Precordial ECG leads

The following symbols appear on the labelling of Phase 3, and throughout this manual:
The operating manual provides valuable information on the proper use of Phase 3.
It is highly recommended that the operator read the instructions thoroughly before
operating the device. It is possible to damage the Device Under Test (DUT) and/or
cause harm to the operator if Phase 3 is used incorrectly
CAUTION: Electrical Shock Hazard, Refer servicing to qualified personnel

CAUTION: Consult Accompanying Documents
These warnings appear on the serial number label of Phase 3. Phase 3 measures hazardous
electrical voltages which MAY BE present when the covers are removed. The operator should read
the Operating Manual to determine what actions to take in the event of failure of Phase 3. Refer to
the Troubleshooting and Maintenance section of the Operating Manual.
In order to ensure ongoing performance accuracy, a TEST mode is provided on the Main Menu
(refer to section 4.3.1). It is recommended that this feature be used on a routine basis, or any time
a test result is in question.
NOTE: Protection of the operator may be compromised if the instructions in this

manual are not followed, or if Phase 3 is used for a purpose not specified in this
manual.
CAUTION: This device measures high voltage signals. For protection of the
operator, inspect the Paddle Adapter and the interconnecting Paddle Adapter Cables
on a regular basis for nicks, cracks or other damage that may compromise the
insulating properties of the housing, wire or connectors. Replace any damaged or
worn components immediately.

Compliance With Standards

Phase 3 has been certified to meet the following safety standards:
CAN/CSA-C22.2 No. 61010-1-(2nd Edition) - Safety Requirements for Electrical Equipment for
Measurement, Control, and Laboratory Use, Part 1: General Requirements
UL Std. No. 61010-1 (2nd Edition) - Safety Requirements for Electrical Equipment for
Measurement, Control, and Laboratory Use - Part 1: General Requirements
IEC/EN 61010-1 (Ed.2.0) - Safety requirements for electrical equipment for measurement, control,
and laboratory use - Part 1: General requirement
Following manufacture, all units are subjected to, and have passed the requirements of the ‘Routine
Tests’ defined in Annex F of the above Standard(s).
2 OVERVIEW
2.1 General Description
2.1.1 Test Capabilities
Phase 3 is a portable, automated system for verifying performance of defibrillators and

transcutaneous pacemakers of all types, including defibrillators which produce monophasic,
biphasic, and Multipulse Biowave® discharges. Phase 3 provides menu-driven procedures which
allow you to test:
Delivered Energy Measure the output energy of a defibrillator when it is discharged

into Phase 3. Along with energy in joules, also measures peak
voltage, current and duration of the discharge pulse.
Charge Time Measure the time required for a defibrillator to charge up to its
maximum energy setting. After charging, measures the energy
delivered when the defibrillator is discharged into Phase 3.
Cardioversion Verify the ability of a defibrillator to correctly synchronize its

discharge to the QRS complex of the electrocardiogram.
Monitor Performance Check the ECG monitor and chart recorder of a defibrillator with
performance waves, normal sinus rhythms, and a wide variety of
arrhythmias provided by the full-featured ECG simulator of
Phase 3.
AED Performance Verify the ability of an Automated External Defibrillator (AED) to

correctly recognize life-threatening arrhythmias and advise delivery
of a shock at the appropriate energy.
Pulse Characteristics Measure amplitude, rate and width of pulses generated by the
transcutaneous pacemaker of a defibrillator.
Overview/Chapter 2 # Page 11
Noise Immunity Verify the ability of a transcutaneous pacemaker to reject line

frequency interference in the electrocardiogram.
Sensitivity Determine the smallest QRS complex that a transcutaneous
pacemaker will recognize as valid.
Refractory Period Determine the paced refractory period (PRP) and sensed refractory
period (SRP) of a transcutaneous pacemaker.
Phase 3 incorporates one fixed 50 ohm load for defibrillator testing, and a variable load for pacer
testing that may be set from 50 to 1600 ohms in 50 ohm steps. To accommodate requirements of
the IEC60601-2-4 standard for defibrillators, the Variable Load Module (VLM) may be added to
Phase 3 as an optional accessory, allowing the user to perform energy tests with an alternative
defibrillator load ranging from 25 to 175 ohms in 25 ohm steps.
Phase 3 may be powered from its internal NiCad battery or from AC power using the accessory
adapter provided with the unit. The rechargeable battery can provide up to 24 hours of continuous
operation.
Phase 3 is small and light-weight, allowing you to easily carry the analyzer to institutional areas
where defibrillators are located. As you perform each test, results can be saved to the non-volatile
Data Log of Phase 3, for later review on the LCD, output to an attached printer, or download to a
personal computer.
2.1.2 Data Log
Phase 3 incorporates a non-volatile memory or "data log" which is used to save test results or Test
Records. For each defibrillator tested, Phase 3 can create a Test Record containing energy, charge
time and cardioversion test results, which may be combined with results from ECG and
transcutaneous pacemaker tests. The non-volatile memory of Phase 3 provides storage for up to 80
such Test Records, each Record being identified by the control number of the defibrillator tested.
The non-volatile memory can also be used to store up to 10 defibrillator discharge waveforms as
Wave Records. Test Records and Wave Records can be downloaded to a personal computer by
means of Phase3pc software, included on CDROM with the analyzer.
2.1.3 Automated Testing
For fully automated testing, Phase 3 provides 32 AutoSequences which may be user-programmed
by means of Phase3pc software. An AutoSequence test may include steps for measuring
defibrillator energy, charge time, and synchronization delay; ECG performance; and pacemaker
pulse characteristics, noise immunity, sensitivity, and refractory periods. Phase 3 comes equipped
with pre-programmed AutoSequences loaded into its non-volatile memory, which can be modified
or supplemented as desired via Phase3pc software.
For each test or measurement performed in an AutoSequence, the expected value of the result or
target is specified, so that Phase 3 will automatically pass or fail the result depending on an
acceptance range derived from the target and a selected tolerance. In manual tests, target and
tolerance parameters may be optionally entered "on the fly", while measurements are being taken.
2.1.4 Connectivity
Phase 3 has two communication ports: Serial I/O and USB. The Serial I/O interface is an RS-232
Port that may be connected to a personal computer, accessory barcode reader, serial printer, or
automated testing system such as the ES601Plus Automated Safety Analyzer. The USB Port is
intended solely for rapid data transfer to a personal computer using the accessory Phase3pc
software. To permit rapid data entry of equipment control numbers, Phase 3 also provides a PS/2
Port which may be connected to a standard PS/2 keyboard, or to a PS/2 barcode reader.
2.1.5 Viewing and Saving Defibrillator Waveforms
In addition to providing an analog output suitable for connection to a conventional oscilloscope,

Phase 3 provides a number of unique features related to defibrillator waveform capture and
examination, including:
Show Waveform After discharging a defibrillator into Phase 3, view the captured
waveform on the Phase 3 graphical LCD. Three selections for both
vertical and horizontal axes are provided, allowing you examine the
waveform in greater detail.
Playback Play back the captured defibrillator waveform into the ECG monitor
or chart recorder of the defibrillator, with 200:1 timebase expansion.
Phase 3 may be configured to automatically playback the waveform
following detection of a valid defibrillator discharge.
Wave Records Save the captured waveform as a Wave Record, for later download
and graphical plotting by the accessory Phase3pc software
(included). To allow a greater number of Wave Records to be stored,
the signal data is compressed by Phase 3 before saving.
Real-Time Capture Capture high-resolution signal data immediately after a defibrillator

discharge, by rapid data transfer via USB to a personal computer
running Phase3pc software. Real-time wave capture may also be
performed via RS-232 when Phase 3 is operating in remote control
mode.
Wave Records are meant to provide a qualitative "snap shot" of the defibrillator signal, but for some
types of discharges, data resolution of the compressed waveform may be insufficient for detailed
numerical analysis such as might be required in a laboratory investigation or research. As an
alternative to Wave Records, Phase 3 in conjunction with Phase3pc software can provide real-time
waveform capture of a discharge. With real-time capture, Phase3pc can produce a graphic chart of
the waveform data on the PC screen immediately after a discharge, accompanied by the analysis
results such as energy, voltage, current and pulse duration. High-resolution waveform data can then
be saved as a file on the PC for later recall, or for export to other data analysis programs such as a
spreadsheet.
2.1.6 Principle of Operation
In principle, Phase 3 is a waveform analyzer that determines the characteristics of an electrical

discharge signal produced by a defibrillator and/or transcutaneous pacemaker. These
characterizations include: signal energy, peak current, peak voltage, pulse width, pulse rate, and
refractory intervals.
Measurements are accomplished by sampling the defibrillator signal from the defib pads or from the
pacer terminals at a high speed. Sampling is triggered by either the rising or falling edge of the input
signal, ensuring the waveform will be captured even if the operator connects the defib or pacer to
Phase 3 with reversed polarity.
Once Phase 3 is triggered, the signal is digitized with 13 bits of precision and approximately 58
milliseconds of signal data having a sample interval of 11.4 microseconds are then stored. After
acquiring the signal data, Phase 3 calculates test results based on the samples. As each measurement
result is derived (energy; voltage; current; and so on), the result is temporarily stored in the Clip
Record which is located in volatile memory (RAM). Once all tests have been completed, the user
can save the test results by entering an equipment control number for identification and then
transferring the contents of the Clip Record to a Test Record in the non-volatile Data Log.
2.2 Controls and Interface Connections
Figure 1 illustrates the user controls and electrical interfaces of Phase 3. The electrical interfaces are
described in Chapter 3 of this manual. Operation of Phase 3 via the keypad and LCD is described in

Setup/Chapter 3 # Page 17
b. If you wish to test a defibrillator having external paddles, connect the Adult Paddle
Adapter included with Phase 3 to the Defibrillator Input using the Paddle Adapter
Cable (Figure 2). At each end of the cable, depress the catch on the plug, fit the plug all
the way into the mating receptacle, then release the catch to lock the cable securely in
place.
Figure 2 - Connection to defibrillator under test.
Alternatively, for hands-free testing, you may connect the output of the defibrillator
directly to the Defibrillator Input of Phase 3 by means of a suitable adapter cable. An
unterminated defibrillator adapter cable is available as an optional accessory (Datrend
P/N 7200-445).
NOTE:
When using unterminated cable 7200-445, you should observe

polarity of the connection as indicated on the Defibrillator Input
label [STERNUM(-); APEX(+)]. Reverse polarity connection
cannot damage Phase 3 or produce incorrect measurement
results, however, the defibrillator waveform may appear inverted
if viewed on the Phase 3 LCD.
An adapter set for testing internal paddles is also available as an optional accessory
(Datrend P/N 7400-443). Refer to the information sheet supplied with the Internal
Paddle Adapter Set for instructions on how to fit these adapters to the pads on the
Adult Paddle Adapter.
c. Connect ECG leads from the defibrillator under test (DUT) to the ECG simulator
outputs located on left and right side panels of Phase 3 (Figure 1). Connections for
standard 3- or 5-wire ECG patient cables (RA; RL; LA; LL; V) are provided on the
right side panel of Phase 3; optional chest connections (V2-V6) for diagnostic ECG are
located on the left side panel. Phase 3 accepts standard or safety-style banana plugs for
the ECG connections. An Adapter Set which can interface Phase 3 to snap-style ECG
patient leads is available as an optional accessory (Datrend P/N 7500-425).
d. If testing of a transcutaneous pacemaker is required, connect the pacemaker output to

the PACER INPUT terminals located on the left side panel of Phase 3 (Figure 3). The
PACER INPUT connections will accept standard or safety-style banana leads. An
unterminated pacemaker adapter cable is available as an optional accessory (Datrend
P/N 7200-446).
Figure 3 - Connection for pacemaker testing.
IMPORTANT:
DO NOT DISCHARGE A DEFIBRILLATOR

INTO THE PACER INPUT OF Phase 3.
DOING SO WILL DAMAGE Phase 3 AND WILL

VOID THE WARRANTY.
3.2 Optional Connections
Refer to Figure 1 to locate the optional interface connections described in this section.
3.2.1 High-Level ECG Output
A high-level analog output signal from the Phase 3 ECG simulator is available at the 1V ECG jack
located on the right side panel. This is a 1/8" monaural phono jack having the signal on the tip
connection and ground on the sleeve. This output is capable of driving a load of 10k ohms or
higher.
The signal amplitude observed at the 1V ECG jack depends on the SCALE setting of the ECG
simulator. At this jack, the QRS complex of the ECG will have 1 volt peak amplitude when the
simulator is set to "x1 scale"; 2 volt amplitude on "x2 scale"; and 0.5 volt amplitude on "x0.5 scale".
3.2.2 Waveform Output
The WAVEFORM output is located on the right side panel of Phase 3 and is intended for
connection of an oscilloscope or similar instrument. The WAVEFORM output is a 1/8" monaural
phono jack having the signal on the tip connection and ground on the sleeve.
When performing defibrillator tests, the WAVEFORM output will provide a scaled analog signal
representative of the defibrillator discharge. When LOW RANGE energy measurement is selected,
the WAVEFORM output provides 1 volt output per 200 volts at the Phase 3 Defibrillator Input
(200:1 attenuation). When HIGH RANGE energy measurement is selected, the WAVEFORM
output provides 1 volt output per 1000 volts at the Defibrillator Input (1000:1 attenuation).
When performing pacemaker tests, the WAVEFORM output provides a scaled analog signal
representative of the pacemaker pulse train. In this case, the WAVEFORM output provides 1 volt
output per 50mA at the Phase 3 PACER INPUT. The WAVEFORM scale remains constant
regardless of the pacemaker load selected for the test.
3.2.3 Serial (RS-232) Input/Output
The Serial I/O Port of Phase 3 can be used to interface to any one of the following RS-232
peripheral devices.
Personal • Controls Phase 3 remotely through a COM port

Computer using the remote command instruction set.

IMPORTANT:
Never connect a RS-232 Barcode Reader to Phase 3 if the power

is on. The Barcode Reader is powered from Phase 3 and may be
damaged if “hot-plugged”. Always turn Phase 3 off BEFORE
connecting a RS-232 Barcode Reader to the Serial I/O Port.
3.2.4 Keyboard Port
The Keyboard Port of Phase 3 is intended for optional connection of a PS/2 personal computer
keyboard, or alternatively, a PS/2-compatible Barcode Scanner (Datrend P/N 7600-052; optional
accessory).
Connection of a PS/2 keyboard or barcode scanner to Phase 3 is optional but simplifies entry of an
ID, such as an equipment control number, for the defibrillator under test (DUT). Alternatively, the
keypad of Phase 3 may be used to enter a DUT ID if an external keyboard or barcode scanner is
not available.
IMPORTANT:
Never connect a PS/2 device (Keyboard or Barcode Scanner) to

Phase 3 if the power is on. The PS/2 device is powered from
Phase 3 and may be damaged if "hot-plugged". Always turn
Phase 3 off before connecting a PS/2 device.
3.2.5 USB Port
The USB Port of Phase 3 is intended to work specifically with Phase3pc software, supplied with
Phase 3 on CD ROM as a standard accessory (Datrend P/N 6950-004). A USB cable is also
provided with Phase 3 as a standard accessory (Datrend P/N 3140-440).
Phase 3 may be "hot-plugged" to the PC using the supplied USB cable at any time while the
instrument is running. Once Phase3pc successfully detects Phase 3, data may be transferred to or
from the PC via the high-speed USB connection.
With Phase3pc sofware, you can:
• Create, modify, save, and print automated sequences of defibrillator and pacemaker tests
("AutoSequences"). AutoSequences created with Phase3pc can be uploaded into the non-
volatile memory of Phase 3. AutoSequences stored in Phase 3 can be downloaded to
Phase3pc for editing and re-uploading to Phase 3.
• Download Test Records stored in the non-volatile Data Log of Phase 3. Phase3pc generates
Test Report documents from the Test Records, which you can then print, save to disk, or
export to equipment management software.
• Download Wave Records stored in the non-volatile memory of Phase 3. Phase3pc generates
graphical plots of the waveform data which you can then print or save to disk.
• Acquire high-resolution samples of defibrillator discharge waveforms, using the real-time

waveform capture mode.
Refer to Chapter 6 of this manual for more information on installing and using Phase3pc software.

are shown on the display immediately above each key. In this manual, these keys are referred to as
"softkeys". Four additional keys labelled with arrows take specific functions depending on the state
of the display.
Figure 7 - Phase 3 keypad functions.
Operation/Chapter 4 # Page 29
These keys are used to respectively increment or decrement displayed data.

Alternatively, these keys may be used to scroll through a list of displayed items.
These buttons will have a repeating action if pressed and held down. When these
keys are active, >? symbols will appear on the LCD display at the far right.
These keys will remain inactive until the > ? symbols are displayed.
Press this button to access additional softkey functions "on the right". This
button becomes active whenever a < symbol appears on the display at the
bottom righthand corner, for example, as shown in Figure 7.
Press this button to access additional softkey functions "on the left". This button
becomes active whenever a = symbol appears on the display at the bottom
lefthand corner.
4.1.2 Clip Record
As defibrillator and pacemaker tests are performed with Phase 3, the individual test results are
collected in a temporary area of memory which is designated the Clip Record. When testing is
complete and results are to be saved, the contents of the Clip Record are then copied to a Test
Record, which resides in non-volatile memory. When a Test Record is recalled from non-volatile
memory for viewing or printing, the Record data is placed in the Clip Record.
The Clip Record is in volatile memory and any data stored in it will be lost if Phase 3 power is
interrupted before the Clip Record data is saved as a Test Record. Test Records saved in non-
volatile memory are retained when the power to Phase 3 is switched off.
As Phase 3 is used to perform individual measurements and tests, the Clip Record will progressively
accumulate the following data:

• Date and Time of test
• Defibrillator test data (energies, charge time, cardioversion sync delays)
• ECG test data (waveform and test result)
• Pacemaker test data (test load, pulse characteristics, and results of immunity, sensitivity
and refractory period tests)
Data accumulated in the Clip Record may be reviewed at any point during the manual testing
process by pressing the VIEW button on the MANUAL TEST menu (see Section 4.4).
4.1.3 CANCEL Key Operation
CANCEL is a special softkey that is used throughout the operator interface of Phase 3. CANCEL
allows the user to cancel a measurement in progress, or a series of previously-acquired
measurements, and return the operator interface to a higher level menu from which various types of
measurements are selected.
Pressing CANCEL can lead to erasure of selected test data in the Clip Record. The amount and
type of data erased will depend on which user interface menu is being displayed when CANCEL is
pressed. CANCEL has increasing impact on the Clip Record data as the level of the menu in the
user interface increases.
At the lowest level, if CANCEL is pressed immediately after a measurement is taken, then the
result of that single measurement is discarded without confirmation, and will not be copied to the
Clip Record. For example, if you measure a defibrillator energy, you may press CANCEL
immediately after the measurement is displayed to discard that single result. You may then repeat the
energy measurement. If a softkey other than CANCEL is pressed following an energy
measurement, then the energy result is copied to a designated location in the Clip Record.
If CANCEL is pressed before a measurement is taken, but after a number of measurements of the
same type have been performed, then all measurements of that type will be deleted from the Clip
Record, but only if you confirm the cancellation when prompted by Phase 3 (see Figure 8).
CANCEL TESTING
Cancel testing? (the current

test will be deleted from the Clip
Record).
YES NO
Figure 8 - Confirmation prompt for CANCEL keypress.
For example, if you measure a series of defibrillator energies and then press CANCEL before
completing the next energy measurement, then all energy measurement data accumulated in the Clip
Record will be deleted if YES is pressed in response to the prompt of Figure 8.
Various types of defibrillator tests, including energy, charge time and cardioversion, are selected via
the DEFIBRILLATOR TEST menu which is described in Section 4.5 of this manual. If CANCEL
is pressed on the DEFIBRILLATOR TEST menu, then all energy, charge time and cardioversion
results being held in the Clip Record will be deleted, but only if you confirm the cancellation by
pressing YES when prompted by Phase 3 (Figure 8). However, only the defibrillator test data will
be affected; ECG and pacemaker results that may also be present in the Clip Record are not
disturbed if CANCEL on the DEFIBRILLATOR TEST menu is pressed and confirmed. The
CANCEL softkey has similar deletion scope on the ECG and PACER TEST menus, as described
later in this manual.
If CANCEL is pressed and confirmed at the highest level of menu in the user interface, for example
the MANUAL TEST menu (Section 4.4), then all test data currently stored in the Clip Record will
be deleted.
If CANCEL is pressed on a menu which is used for entering data or setting a test parameter, the
effect of CANCEL is to discard any changes that may have been made to the parameter being
edited. Examples include menus for the ECG simulator, data entry of target and tolerance, and ID
(control number) entry. In these cases, pressing CANCEL has no effect on the contents of the Clip
Record.
The deletion scope of the CANCEL softkey is explicitly specified in each Section of this manual
which discusses a user interface screen having a cancel function. When in doubt, refer to the
pertinent Section to determine exactly what potential effect CANCEL may have on the Clip
Record.
4.1.4 User Preference Settings
Certain parameters or settings in the Phase 3 are meant to be set to the operator's test preference.
These parameters, once set, will remain at that setting until specifically changed by the operator.
These parameters will retain their setting after the power is turned off, and will be in effect the next
time power is applied. The parameters that exhibit this behaviour are:
• ECG Simulator MODE (refer to section 4.5.1.2)

• Playback length (refer to section 4.5.1.2)
• Pacer amplitude measurement METHOD (refer to section 4.7.2)
• Pacer Load (refer to section 4.7.1)
• Refractory Test ECG WAVE (refer to section 4.7.3)
• Refractory Test ECG scale (refer to section 4.7.3)
• Pacer Noise Immunity Frequency (refer to section 4.7.4.1)

Press YES to proceed with the selected manual test, or NO to retain the current contents of the
Clip Record and return to the MANUAL TEST menu.
Once you have started testing a defibrillator or pacemaker and have collected measurement data in
the Clip Record for these types of DUT, you cannot then change to testing an Automated External
Defibrillator (AED). This is because AED measurement data is incompatible with the measurement
data obtained from testing a conventional defibrillator/pacemaker. If AED is selected from the
MANUAL TEST menu, and the Clip Record already contains measurement data from defibrillator
and/or pacemaker tests, then the error message of Figure 22 is displayed.
CANNOT PERFORM THIS TEST

4.5.1.2 Setting the ECG Simulator
Pressing the ECG softkey on the ENERGY TEST menu causes Phase 3 to display a menu for
setting up the ECG simulator (Figure 27, page 50). The ECG simulator provides a total of 55
Waveforms which are organised in seven Wave Banks. Depending on the test being performed,
certain banks may be disabled as the waveforms contained within those banks are not applicable to
the test.
The display of Figure 27 shows the WAVE BANK and the full title of the WAVEFORM currently in
effect, as well as an abbreviated waveform title which is shown on the display immediately below the
full title. The abbreviated waveform title (e.g. VFIB1) may be used in place of the full title on some

4.5.1.3 Setting a Target and Tolerance
Phase 3 allows you to optionally specify a target or expected value for a measurement to be made,
and a tolerance or acceptance range which spans either side of the target. If a target and tolerance
have been entered, Phase 3 will automatically compare the measurement result to the target when
the measurement is performed. If the difference between the measurement result and the target lies
within the tolerance range, Phase 3 will automatically assign a "PASS" to the result. If the difference
lies outside the tolerance, Phase 3 will automatically assign a "FAIL" to the result.
Entering tolerances and targets for manual measurements is always optional. If you do not wish to
enter a target and tolerance, you can simply "PASS" or "FAIL" any test result yourself, via
corresponding softkeys provided on the Phase 3 keypad, and thereby manually store the result with
your pass/fail assessment in the Clip Record.
Press the TARGET softkey on the ENERGY TEST menu to display a menu for inputting an
energy target and tolerance (Figure 30).

4.5.1.4 Performing the Energy Test
The purpose of the energy test is to verify that a defibrillator accurately delivers the amount of
energy which has been selected by the operator. In addition to delivered energy, the test reports
other parameters of the defibrillator discharge, such as voltage, current and pulse width, so that
conformance to manufacturer's specifications can be confirmed. Normally, a number of different
energy settings will be tested, for example: 10, 20, 50, 100, 200, 300 and 360 joules.
To perform a defibrillator energy test:
a. Connect the defibrillator under test (DUT) to Phase 3 according to Section 3.1.
b. Optionally, if you would like to capture high-resolution waveform data in real-time,

connect the USB Port of Phase 3 to a personal computer using the supplied USB cable,
then run Phase3pc software on the PC (see Chapter 6 for more information on
installing and using Phase3pc software).
c. On the DEFIBRILLATOR TEST menu, press ENERGY. The display of Figure 32

will appear.

f. Optionally, if you would like to change the waveform of the ECG simulator, press ECG
to view the ECG setup menu. Refer to Section 4.5.1.2.
g. Optionally, if you would like to have Phase 3 automatically pass or fail the measurement
you are about to take, press TARGET, enter a target energy, and select a tolerance.
Refer to Section 4.5.1.3.
h. If using external or internal paddles, apply the paddles firmly to the Phase 3 Paddle
Adapter.
i. Charge the DUT.
j. Discharge the DUT into Phase 3. Peak current and voltage readings will appear on the
display immediately after the discharge. Phase 3 will calculate the energy and display
the result in Joules. The energy calculation will require approximately four seconds to
complete. Depending on the ECG MODE settings (see section 4.5.1.2), Phase 3 may
automatically play back the defibrillator pulse waveform to the ECG terminals and
paddle plates, then change the ECG output to normal sinus rhythm ("NSR60").
k. If the measurement is being performed on LOW range, and Phase 3 detects distortion
(clipping) in the acquired waveform data, Phase 3 will produce an alarm message on the
display (Figure 33). The measurement results are invalid if this alarm is displayed.

softkeys, then the Clip Record location reserved for energy test #10 will be overwritten
with each new result.
q. When all tests have been completed, press DONE (see Figure 32). Energy results
accumulated in the Clip Record are retained and may be supplemented with data from
other defibrillator, ECG and pacemaker tests.
4.5.1.5 Viewing and Saving Defibrillator Waveforms
Phase 3 provides unique features for viewing and saving the waveform of a defibrillator discharge.
These features are enabled after completion of each energy measurement, via the PLAYBACK,
SHOW WAV and SAVE WAV softkeys described in the preceding Section.
PLAYBACK After an energy measurement, press this softkey to play back the captured
defibrillator waveform into the ECG monitor or chart recorder of the DUT, via the
ECG simulator of Phase 3. The display will appear as shown in Figure 37 as the
playback progresses. To stop a playback in progress, press the CANCEL softkey at
any time.

WIDTH @10%: 14.34 msec @50%: 8.11 msec
ECG Wave: PLAYBACK....................
CANCEL
Figure 37 - Playback of captured waveform via ECG simulator.
If the energy measurement was performed on HIGH range, an ECG monitor set to
Lead II will show 1mV for each 1000V of defibrillator signal, or 1mV for each
2000V if the signal is being observed at the contact pads of the Phase 3 Paddle
Adapter. If the measurement was performed on LOW range, an ECG monitor on
Lead II will show 1mV per 200V of defib signal, or 1mV per 400V at the Paddle
Adapter. Each second of signal shown on the ECG monitor or chart recorder will
correspond to 5 milliseconds of the defibrillator waveform (200:1 timebase
expansion).
The length of the play back will be determined by the PLAYBACK MODE setting
(refer to section 4.1.5.2). Play back of the entire waveform requires approximately
12 seconds. The alternative PLAYBACK MODE will play back the first 1/3 of the
waveform data, which will require approximately 4 seconds. In most cases, this will
display the complete signal of interest.
Waveform playback may also be initiated automatically after a defibrillator discharge,

by selecting the appropriate option for the SIMULATOR MODE of the ECG
SETTINGS function (refer to section 4.1.5.2). In this mode, playback will occur
immediately after the waveform parameters have been calculated and displayed on
the LCD.
SHOW WAV After an energy measurement, press this softkey to view the captured defibrillator
waveform on the Phase 3 display (Figure 38).
Figure 38 - Example of captured waveform display.
When viewing a defibrillator waveform with the SHOW WAV function, the
Phase 3 keypad operates as follows:
?> Contract/expand the vertical scale. The available choices depend on the
energy measurement range, as follows:
HIGH range LOW range

• 0 to ±25 Amps • 0 to ±5 Amps
• 0 to ±50 Amps • 0 to ±10 Amps
• 0 to ±100 Amps (default) • 0 to ±20 Amps (default)

msec of data.
DELETE Delete the last Wave Record that was saved to the non-volatile
memory. A prompt requiring you to confirm the deletion will
be displayed if this softkey is pressed. This function allows you
to replace a previously-saved waveform with the current
waveform.
STORE Save the waveform data to the non-volatile memory as a Wave
Record. The record counter shown at the top right corner of
the display will be incremented by one. The maximum number
of waveforms that can be saved is 10. This softkey will not
appear on the display once there are ten Wave Records in
memory. If the memory is full, use the DELETE softkey to
remove unwanted Records to make space for new Records.
CANCEL Return to the previous menu without saving the Wave Record.
NOTE:
The defibrillator waveform data is always compressed when

Phase 3 creates a Wave Record, in order to conserve memory
space. The compressed signal data adequately represents a
defibrillator waveform for qualitative purposes, such as graphing
a picture of the waveform. For detailed numerical analysis of the
waveform data, such as might be done in a laboratory-based
investigation or research, the real-time waveform capture mode
should be used. Refer to Section 4.5.1.6.
Once Wave Records have been saved to the non-volatile memory, the Records may later be
downloaded into Phase3pc software for graphical plotting and printing. Refer to Chapter 6 for
details.
4.5.1.6 Capturing the Defibrillator Waveform in Real-Time
Phase 3 with Phase3pc software provides a feature for capturing high-resolution waveform data on
a personal computer. The data can be acquired after each defibrillator energy measurement is
completed, while the display is in the state shown in Figure 34 or Figure 36.
Clicking the Waveform Capture icon in Phase3pc causes the detailed waveform data to be
rapidly transferred to the PC via the USB connection. After a waveform graph is plotted, Phase3pc
allows the user to print the graph or save the detailed data to a file for further numerical analysis.
Refer to Section 6.5.3 for additional details.
Defibrillator waveform capture may also be performed via RS-232 when Phase 3 is operating in
remote control mode. Refer to Chapter 5 for details.
4.5.2 Defibrillator Charge Time Test

The intent of this test is to determine if the battery of the defibrillator is in reasonable condition and
will be able to charge the defibrillator, even when under some stress from clinical use. The
defibrillator should first be unplugged from the AC power. Prior to beginning the actual charge
time test, the defibrillator may now be discharged into Phase 3 several times. The number of pre-
test discharges will be tracked and reported in the upper right corner of the screen. These pre-test
discharges are counted, but they are not analyzed. When the requisite number of pre-test discharges
have been made, the actual charge time measurement can be initiated by pressing the START
softkey. The number of pre-test discharges will be reported in the final test report.

4.7.2.2 Performing the Pulse Test
The purpose of a pacemaker pulse test is to verify that the pacemaker output signal is in
conformance with manufacturer's specifications for a given load resistance. Phase 3 provides space
in the Clip Record for up to 10 pulse tests, allowing you to record the results for different settings of
pacemaker output current and pulse rate.
To perform a pacemaker pulse test:
a. Connect the output from the transcutaneous pacemaker of the defibrillator under test
(DUT) to Phase 3 according to Section 3.1.
b. Select the pacemaker load (Section 4.7.1) according to testing requirements specified by
the DUT manufacturer. Typically, the load corresponds to the largest resistance into
which the pacemaker can deliver its maximum rated output current. Refer to the
manufacturer's service manual for the DUT to determine the required load.
c. On the PACER TEST menu, press PULSE. The display of Figure 56 will appear.
d. Set the DUT to asynchronous or non-demand operating mode.
e. Set the output current and pulse rate on the DUT to the desired values.
f. Optionally, if you would like Phase 3 to automatically pass or fail the measured pulse
amplitude, press AMPL and enter a target value and tolerance.
g. Optionally, if you would like Phase 3 to automatically pass or fail the measured rate,
press RATE and enter a target value and tolerance.
h. Optionally, if you would like Phase 3 to automatically pass or fail the measured pulse
width, press WIDTH and enter a target value and tolerance.
i. Select the amplitude measurement METHOD. The required method may be specified
by the manufacturer in the DUT service manual. If the manufacturer does not specify a
method, or if the DUT service manual is not available, choose "Average".
j. Press START to measure the pacemaker pulse. The START softkey will be changed
to a STOP softkey (Figure 58). The first measurement will be completed and the
results displayed after two successive pacemaker pulses are detected. Phase 3 will
continue to acquire and analyze pacer pulses until the STOP softkey is pressed. Each
time the results are displayed on the screen, Phase 3 will emit an audible 'click'.
NOTE: the audible 'click' is not an indication of the pacer rate, only an indication that new
data is on the display. Generally, the 'click' will occur every 2 to 3 pacer pulses, depending
on the rate. For a given rate, the 'click' will be periodic and a missing 'click' may indicate
Phase 3 encountered a pulse that was difficult to analyze. Frequent missing 'clicks' may be
an indication that the pacer pulses are of an abnormal shape or inconsistent rate.

4.7.2.3 Capturing the Pacemaker Waveform
Phase 3 with Phase3pc software provides a feature for capturing high-resolution waveform data on
a personal computer. The data can be acquired after the STOP softkey has been pressed, while the
display is in the state shown in Figure 58 or Figure 59.
Clicking the Waveform Capture icon in Phase3pc causes the detailed waveform data to be
rapidly transferred to the PC via the USB connection. After a waveform graph is plotted, Phase3pc
allows the user to print the graph or save the detailed data to a file for further numerical analysis.
Refer to Section 6.5.3 for additional details.
Pacemaker waveform capture may also be performed via RS-232 when Phase 3 is operating in
remote control mode. Refer to Chapter 5 for details.

instructions on how to input a target. The MAX limit range is 50 - 750 msec.
CANCEL Cancel the refractory period test and return to the PACER TEST menu. Refractory
period data in the Clip Record will be deleted if you press YES in response to the
cancellation confirmation which will be displayed. All other data in the Clip Record
will be retained. For additional information on CANCEL, see Section 4.1.3.
Note: The "ECG WAVE" and "Scale" for the refractory test, set by means of the ECG menu, are
User Preference Settings that will remain in effect until changed by the operator. When
operating the Phase 3 in manual test mode, the changes made here will apply to the
refractory test currently in progress as well as to future tests, even if the Phase 3 power is
switched off and then back on.
4.7.3.2 Performing the Refractory Period Test
The purpose of a pacemaker refractory period test is to verify that paced and sensed refractory
periods are per manufacturer's specifications for the DUT. These intervals are defined as follows:
• Refractory Period: When a pacemaker is operating in synchronous or demand

mode, the "refractory period" is the time interval during
which the pacemaker is insensitive to an ECG input signal,
and in particular, the QRS complex of the ECG.
• Paced Refractory Period (PRP): Immediately after generation of a pacing pulse, PRP is the
time interval over which the pacemaker remains insensitive
to the ECG. If a QRS occurs within the PRP following
output of a pacing pulse, the pacemaker ignores this QRS.
• Sensed Refractory Period (SRP): SRP is the time interval after a detected QRS during which
the pacemaker remains insensitive to the ECG. If a QRS
occurs within the SRP following a detected QRS, the
pacemaker then ignores this second QRS.
Phase 3 provides space in the Clip Record for up to 2 refractory period tests, allowing you to record
results for different rate settings on the pacemaker, or for different trigger waveforms on the
Phase 3 ECG simulator.
To perform a refractory period test:
b. If no pacemaker tests have yet been performed, select the pacemaker load (Section
4.7.1) according to testing requirements specified by the DUT manufacturer. Do not
change the load if the Clip Record contains data from previous pacemaker tests.
c. On the PACER TEST menu, press REFRACT. The display of Figure 61 will appear.
d. Set the DUT to synchronous or demand operating mode.
e. Set the output current and pulse rate on the DUT. The output current should be set to
approximately mid-range. A pacer rate ranging from 60 to 120 PPM is recommended.
Rates in excess of 120 PPM should be avoided.
f. On Phase 3, optionally press ECG to modify the settings of the ECG simulator as
g. Optionally, if you would like Phase 3 to automatically pass or fail the measured refractory
intervals, press MIN and enter a minimum allowed refractory period, then press MAX
and enter the maximum allowed period.
h. Press START to start the test. The test proceeds as a number of successive pacemaker
pulses are acquired. First, Phase 3 determines the pacemaker's pulse rate, which is
displayed on the LCD as PACER RATE. Then, Phase 3 will determine the PRP by
outputting ECG trigger pulses after each pacing pulse is detected. Following
determination and display of PRP, Phase 3 then proceeds to determine the SRP.
During the test, Phase 3 will display a progress indicator just above the softkey row. At
a pacer rate of 90 PPM, the entire test will require about 30 seconds to complete.
i. If neither a minimum limit nor a maximum limit has been entered, Phase 3 will display
the results according to Figure 63. Refer to Section 4.5.1.4 for an explanation of the

Note: The NOISE frequency is a User Preference Setting that will remain in effect until changed
by the operator. When operating the Phase 3 in manual test mode, the changes made here
will apply to the immunity test currently in progress as well as to future tests, even if the
Phase 3 power is switched off and then back on.
4.7.4.2 Performing the Noise Immunity Test
The purpose of the noise immunity test is to verify that a pacemaker operating in demand mode
does not respond to line frequency noise at its ECG input.
In this test, Phase 3 outputs a line frequency sine wave via the ECG simulator and observes the
effect on the pacemaker. The test automatically passes if the pacemaker continues to pace at its set
rate when the output of the ECG simulator is set to maximum (6 millivolts peak-to-peak). The test
automatically fails if the pacemaker ceases pacing for a sine wave amplitude less than 6 millivolts.
To perform the noise immunity test:
b. If no pacemaker tests have yet been performed, select the pacemaker load (Section
4.7.1) according to testing requirements specified by the DUT manufacturer. Do not
change the load if the Clip Record contains data from previous pacemaker tests.
c. On the PACER TEST menu, press IMMUNITY. The display of Figure 65 will appear.
f. On Phase 3, set the noise frequency to either 50 or 60 Hz as required.
g. Press START to start the test. The test proceeds as a number of successive pacemaker
pulses are acquired. First, Phase 3 determines the pacemaker's pulse rate. After
measuring the rate, Phase 3 will then begin to output a sine wave to the pacemaker via
the ECG simulator.
h. As each pacer pulse is detected, Phase 3 introduces an audible 'click' and increases the
noise signal amplitude by 0.0845 mV. The test will pass if the pacemaker does not react
to a 6 millivolt sine wave (Figure 66). If there is no activity from the pacer for 4
seconds for any noise level less than 6 mV, the test will fail. At 90PPM, the test will
require about 50 seconds to complete if the pacemaker passes, or less if it fails.
i. Press OK to save the immunity result in the Clip Record, or CANCEL to discard the
result.

4.7.5.2 Performing the Sensitivity Test
The purpose of the sensitivity test is to determine the smallest ECG signal that will reliably trigger a
pacemaker, and to verify this signal level is in accordance with manufacturer's specifications.
Phase 3 provides space in the Clip Record for up to 2 sensitivity tests, allowing you to record results
for different trigger waveforms on the Phase 3 ECG simulator.
To perform the sensitivity test:
b. If no pacemaker tests have yet been performed, select the pacemaker load
(Section 4.7.1) according to testing requirements specified by the DUT manufacturer.
Do not change the load if the Clip Record contains data from previous pacemaker tests.
c. On the PACER TEST menu, press SENS. The display of Figure 67 will appear.
f. On Phase 3, optionally press ECG to modify the settings of the ECG simulator as
g. Optionally, if you would like Phase 3 to automatically pass or fail the measured
sensitivity, press LIMIT and enter a maximum permitted value for the test result.
h. Press START to start the test. The test proceeds as a number of successive pacemaker
pulses are acquired. First, Phase 3 determines the pacemaker's pulse rate, which is
displayed on the LCD as PACER RATE. Then, Phase 3 will determine the sensitivity by
outputting ECG trigger pulses of variable amplitude after each pacing pulse is detected.
During the test, Phase 3 will display a progress indicator (a rotating line) just above the
softkey row.
i. As each pacer pulse is detected, Phase 3 will emit an audible 'click'. For each detected
pacer pulse, Phase 3 will increase the ECG signal level in steps of 0.045mV until the
pacer is inhibited. After the pacer is inhibited, the ECG level is reduced and then
increased in steps of 0.015mV until the pacer is again inhibited. The test will stop when
the pacer is inhibited by the ECG signal, or a maximum ECG level of 3 mV is reached.
For a pacer having a sensitivity of nominally 1 mV, and at a rate of 90PPM, the
sensitivity test will require about 20 seconds.

4.8.2 Performing the AED Test
The primary purpose of the AED test is to determine whether an AED can analyze and correctly
classify an input ECG signal as shockable or not shockable. A second purpose of the test is to
record the energy of the discharge when the AED advises the user to administer a shock, and a
shock is then triggered. Phase 3 provides space in the Clip Record for up to 32 AED test
measurements, allowing you to record results for different ECG waveforms, AED shock series, and
AED energy levels.
In an AED test, the Phase 3 ECG simulator is limited to the waveforms listed in Table 4-1 of
Section 4.5.1.2. These ECG waveforms are classified according to AAMI guidelines1 as follows:
Phase 3 ECG Waveform Waveform Classification
AFIB1 Coarse Atrial Fibrillation Not shockable
AFIB2 Fine Atrial Fibrillation Not shockable
ASYS1 Asystole (baseline > 0.1 mV) Not shockable
ASYS2 Asystole - Flat Not shockable

1. Circulation 1997; V.95:1677-1682 AAMI
According the preceding table, an AED which operates according to AAMI guidelines1 for
sensitivity and specificity should advise a shock only if the ECG clearly indicates ventricular
fibrillation (> 100 ìV), or a wide complex ventricular tachycardia in excess of 150 BPM.
To perform the AED test:
a. Connect the AED to Phase 3 according to Section 3.1.
b. On the MANUAL TEST menu, press AED. The display of Figure 71 will appear.
c. Optionally, if you would like to change the ECG waveform, press ECG to modify the
settings of the ECG simulator. Refer to Section 4.5.1.2.
d. If necessary, press the "ANALYZE" or equivalent button on the AED, or set the AED
to automatically analyze and report on the ECG waveform.
e. If the AED analyzes the waveform and advises you not to shock, press the NO
SHOCK softkey on Phase 3. If this is the correct AED response given the type of
ECG waveform being simulated, Phase 3 will automatically assign a "PASS" to the test
result (Figure 73). The result of the test will be displayed for 3 seconds, a zero energy
result will be saved in the Clip Rec ord, and then the Phase 3 will go back to the screen
of Figure 71 . If the AED' s response is not correct for the selected ECG waveform,
Phase 3 will automatically assign a "FAIL" to the result.

f. If the AED advises you 'to shock', discharge the AED into Phase 3. If this is the
correct response for the type of ECG waveform being simulated, Phase 3 will assign a
"PASS" to the test result (Figure 74). If AUTO-NSR is enabled, the ECG simulator
will output a normal sinus rhythm at 60BPM. The results of the test will be displayed
for 5 seconds, the energy result will be saved in the Clip Record, and then the system
will go back to the screen of Figure 71. If the AED' s response is not correct for the

4.10 Automated Testing
4.10.1 AutoSequence Overview
For fully automated testing, Phase 3 provides 32 AutoSequences which may be user-programmed
by means of the accessory Phase3pc software (included on the CD ROM supplied with your
Phase 3). An AutoSequence test may include steps for measuring defibrillator energy, charge time,
and synchronization delay; ECG performance; and pacemaker pulse characteristics, noise immunity,
sensitivity, and refractory periods. Phase 3 comes equipped with pre-programmed AutoSequences
loaded into its non-volatile memory, which are provided as examples, and should be modified or
supplemented to meet the users needs via Phase3pc software.
For each test or measurement performed in an AutoSequence, the expected value of the result or
target is specified, so that Phase 3 will automatically pass or fail the result depending on an
acceptance range derived from the target and a selected tolerance.
There are two basic types of AutoSequence provided by Phase 3: Defib/Pacer and AED. In a
Defib/Pacer AutoSequence, the order of test execution is:
• Defib Energy
• Defib Charge Time
• Defib Cardioversion (Sync)
• ECG Tests
• Pacer Pulse
• Pacer Noise Immunity
• Pacer Sensitivity
• Pacer Refractory
In an AED AutoSequence, the only type of test that can be performed is the "shock/no shock"
energy test (see Section 4.8). Charge time, cardioversion, and pacemaker tests cannot be performed
if the "DUT Type" of the AutoSequence has been set, via Phase3pc software, to "AED".
When an AutoSequence is selected from the AutoSequence menu of Phase 3, the Clip Record is
erased. As each step of the AutoSequence is completed, the measurement data is accumulated in the
Clip Record. At the end of the AutoSequence, you will be prompted to enter an ID for the
defibrillator under test (DUT), after which a Test Record containing the results will then be saved to
the non-volatile Data Log.

4.10.2 Selecting an AutoSequence
Press the AUTO softkey on the Phase 3 MAIN MENU (Section 4.3) to enter a menu for selecting
an AutoSequence (Figure 83). Press the ? > keys to scroll down/up through the list of
AutoSequences one sequence at a time.

4.10.3 Running a Defib/Pacer AutoSequence
4.10.3.1 Automated Defibrillator Tests
When running an AutoSequence for a defib/pacer, Phase 3 will display test setup instructions for
each step of the sequence, similar to the example of Figure 85 for a defibrillator energy test. The
type of test being performed at any step in the sequence is indicated at the top left of the display
(DEFIB ENERGY in the example of Figure 85). The test count (01) and number of tests to be
performed in the sequence (in this example, 07) are shown at top right.
Any Phase 3 Autosequence can be programmed by the user to have an automatic timeout/advance
feature. At each test step, the Auto-Test Timer of Phase 3 will move the sequence forward from
the user prompt to the measurement automatically, provided there is no operator input before a
user-set delay time expires. After each measurement is completed, the Auto-Test Timer causes the
user prompt for the next step of the sequence to be displayed. The Auto-Test Timer of a
Autosequence may be set to "OFF", or it may be programmed for a 3, 5 or 9-second delay by means
of the Phase3pc software. For example, Figure 85 shows the first energy test of an Autosequence
for which the Auto-Test Timer has been enabled with a delay of 5 seconds. The operator may press
TEST to run the indicated test, or the user can wait for the Auto-Test Timer to count down to zero
at which point the energy measurement screen, Figure 86, will be displayed automatically.

ABORT Press to abort the sequence in progress. A prompt will be displayed asking you to
confirm the abort. Pressing YES in response to this prompt will abort the sequence
and return Phase 3 to the MAIN MENU.
If TEST of Figure 85 is pressed, Phase 3 will then display a screen corresponding to the type of
measurement which is to be performed. For the case of a defib energy test, the display will appear
similar to the example of Figure 86. On this display, the BACK softkey may be pressed to restore
the instruction screen shown in Figure 85.

4.10.3.3 Automated Pacemaker Tests
If the AutoSequence includes pacemaker pulse tests, then this part of the sequence will be preceded
by an instruction display which will be similar to the example shown in Figure 90. As indicated in
the figure, the pacer test load which has been specified in the AutoSequence setup is indicated on
the top line of the display. Softkeys appearing on the display of Figure 90 provide the same
functions as described previously for defibrillator energy tests (see Section 4.10.3.1). The Auto-Test
Timer, if enabled, will not appear on the display of Figure 90 , but the timer will cause the sequence
to automatically advance to the next measurement after a 4-second delay once the pacer pulse test
has been stopped.

4.10.4 Running an AED AutoSequence
When running an AutoSequence for an AED, Phase 3 will operate similarly as described in
Section 4.8 for a manual AED test. The primary difference between a manual AED test and an
AutoSequence AED test is that the ECG waveforms are defined in the setup of an AED
AutoSequence. The Auto-Test Timer cannot be enabled in AED Autosequences.
As in the manual mode, the ECG waveform may be set to revert to NSR60 after a discharge has
been detected. This setting may be toggled using the AUTO-NSR key. After the test result has
been accepted with the OK key, the ECG waveform will change to the setting dictated by the next
step in the AutoSequence.
Upon selecting an AED AutoSequence, the display of Phase 3 will appear as shown in Figure 95.
The softkeys will then assume the following functions:

Trigger Shock or press NO SHOCK to
conclude each test.
ENERGY: ---.-J
ECG TYPE: SHOCKABLE
NO SHOCK AUTO-NSR BACK ABORT

Figure 95 - AutoSequence AED test.

NO SHOCK Press this softkey if the AED audibly and/or visually advises the user that the
AED cannot or should not be discharged. For further details, see Section 4.8.
AUTO-NSR Press this softkey to toggle between changing to NSR60 after a discharge is
detected, and, retaining the current ECG WAVE after a discharge is detected.
The ECG WAVE will change to the next waveform in the sequence when the
results are accepted with the OK key.
BACK Press this softkey to decrement the sequencer to the immediately previous AED
test step.
ABORT Press to abort the sequence in progress. A prompt will be displayed asking you
to confirm the abort. Pressing YES in response to this prompt will abort the
sequence and return Phase 3 to the MAIN MENU.
If NO SHOCK is pressed, or if a discharge is detected, Phase 3 will automatically assess the result
as shown in the example display of Figure 96. When the result is displayed, press OK to save the
result to the Clip Record and advance to the next step of the sequence.

Figure 96 - AED test result during an AutoSequence.
If the AED has delivered a shock, and if the AED has been configured to automatically execute a
"shock series", you should press the OK key before the AED announces that the ECG is being
analyzed. For a shockable ECG waveform, enabling the AUTO-NSR feature of Phase 3 before
activating the "ANALYZE" function on the AED should inhibit the AED's "shock series" after the
first discharge, in which case you will then have more time to respond to the test result with the OK
key. Alternatively, when a shock is delivered be prepared to press OK as soon as the energy result is
displayed; this will depend on the particular shock protocol developed by the manufacturer of the
AED.

5.1 General Description
The Serial I/O Port provides a RS-232 interface for controlling Phase 3 remotely using an external
device such as a personal computer or automated test system. Phase 3 will recognize a predefined
set of commands issued to its Serial I/O Port allowing the external device to start a test, stop a test,
or retrieve test results automatically.
Remote commands allow the creation of simple programs on a personal computer that will
automatically perform and document a defibrillator and/or pacemaker test according to a desired
protocol. The command set is also compatible with automated test instrumentation, such as the
ES601Plus Automated Safety Analyzer. Refer to the Operating Manual for your automated test
instrument, especially with regard to port settings, cable wiring, data transmission format and data
packet length. Note the serial protocol of Phase 3 is 9600 Baud, 8 Data Bits, No Parity, 1 Stop Bit
(9600, N, 8, 1).
The following sections present the remote control command set of Phase 3. When using these
commands, it is assumed the user has connected the DUT to Phase 3 prior to enabling the
controlling device, and the controlling device is connected to Phase 3 using the appropriate interface
cable as described in Section 3.2.3. If using a program on a personal computer to command Phase 3,
allow a delay of at least 100 milliseconds between consecutive remote commands to provide enough
time for Phase 3 to process and respond to each received command.
Remote Control/Chapter 5 # Page 117

5.2 Remote Interface Mode
In order for Phase 3 to respond to remote control commands, it must first be placed in Remote Mode.
Phase 3 will ignore all commands sent unless the instrument is running the Remote Mode interface.
To enter Remote Mode, press the REMOTE softkey on the MAIN MENU of Phase 3. The display
will then appear as shown in Figure 99. Commands received via the Serial I/O Port are displayed
on the LCD, as are the data which are returned in response to the commands. Phase 3 also displays
a counter which increments each time a valid command is received and processed. Between
commands, CANCEL may be pressed to exit Remote Mode to the MAIN MENU of Phase 3.
REMOTE MODE MENU
STATUS: Waiting PORT: RS232

COMMAND: COUNT: 1
CANCEL
Figure 99 - Remote Mode menu.
5.3 Command Set
There are 16 commands in the remote control command set of Phase 3. Each command consists of
a string of upper-case ASCII characters and numerals, terminated by a carriage return character
(<CR> or \r).
If Phase 3 receives a valid RS-232 command, it will execute the command, and return either an
asterisk character followed by a carriage return (*<CR>) or a packet of data back to the controlling
device depending on the type of command issued. With many of the measurement-related
commands, a substantial amount of time may elapse before any data, for example energy test results,
are returned to the controlling device.
If a command is syntactically incorrect, or is not recognized by Phase 3, a question mark character

followed by a carriage return (?<CR>) is transmitted back to the controlling device.

5.3.1 ECG Configuration Command

5.3.14 Acquire Waveform Data Command
Description: The WAV command causes Phase 3 to return the waveform data currently held in
the data acquisition buffer via the RS-232 port.
This command works ONLY after completion of a successful “DE” (defib energy
test) or “PP” (pacer pulse test) command. The data returned in response to “WAV”
will represent a defibrillator discharge waveform after a “DE” command, or a single
pacer pulse after a “PP” command.
Syntax: WAV<length><sample_rate><format><CR>
where: <length> is:

‘1’ to ‘6’ - corresponding to 10 to 60 msec of waveform data
<sample_rate> is:
L - low - corresponding to 45.6usec sample interval
M - medium - corresponding to 22.8 usec sample interval
H - high - corresponding to 11.4 usec sample interval
<format> is:
A - for ASCII format
B - for binary format
Example: "WAV3HA\r"
Return 30 msec of waveform data at a sampling interval of 11.4 usec, in ASCII

format.
Returns: The returned signal sample data are signed values. For a defib waveform, the data
correspond to current in units of amperes x 100 (e.g. a value of -1579 corresponds to
a signal sample equal to -15.79 amperes). For a pacer waveform, the data correspond
to current in units of milliamps x 10 (e.g. a value of +453 corresponds to +45.3
milliamps).
(1) For ASCII return format, each signal sample is represented as a string of
ASCII digits, preceded by a ‘+’ or ‘-’ character to convey the sign as
appropriate, and terminated with a carriage return character (‘\r’). After all
requested signal data have been returned, a form feed character (‘\f’) is then
sent and can be used to detect conclusion of the waveform download in
ASCII mode.

(2) For binary return format, each data value is sent as a signed short (16-bit)
integer, sent in low byte/high byte order. The requesting host can detect
end-of-download via a timeout mechanism, or by waiting for the expected
number of data values to be received. The number of data points conveyed
in the download depends on the command parameters and is listed in the
following table.
<sample_rate>
<length> ‘L’ ‘M’ ‘H’
‘1’ 220 440 880
‘2’ 440 880 1760
‘3’ 660 1320 2640
‘4’ 880 1760 3520
‘5’ 1100 2200 4400
‘6’ 1320 2640 5280

5.3.16 Send Test Report Command
Description: The STR command causes Phase 3 to return the Test Record requested, in the
format of a printed Test Report (see section 4.9.2.2).
Syntax: STR <record_number><CR>
Example: "STR16\r"
Get Test Report 16 from memory and send to PC in print format.
Returns: (1) "ASCII printed report" There is no 'end-of-file ' marker. User must
monitor for a specific text string (such as
Date:), or time out to end the transmission.
(2) "e\r" Record does not exist.

6 Phase3pc SOFTWARE
Datrend Phase3pc software provides a communication utility for Phase 3 which allows the user to
configure AutoSequences, download Test Records and Wave Records, and capture waveform data
in real-time. Phase3pc is a self-contained Windows® application which is supplied as a standard
accessory on CD ROM.
6.1 Installation
6.1.1 Installing Phase3pc
To install Phase3pc to your computer, place the Phase3pc CDROM into your computer's
CDROM drive and close the drive. The installation application will begin automatically
(Figure 100), unless your computer is set to ignore autorun applications.
Figure 100 - Installation of Phase3pc.

In the event the installation program does not start automatically, use the file explorer utility on your
computer to locate the CDROM drive. Browse this drive to locate the file called
Phase3pcNNSetup.exe . Double-click or otherwise execute this file and the installer will guide you
through the installation process. We recommend that all default installation locations be left intact
so future upgrades and enhancements will run smoothly.
At the end of the short installation process, you will be presented with a notification that the
software has been installed, at which time you may either select or deselect the checkbox which asks
if you would like to run Phase3pc upon closing the dialogue box. The computer does not have to
be restarted before running Phase3pc
6.1.2 Installing USB Drivers
When installation of Phase3pc is complete, connect Phase 3 to your PC using the USB cable
provided with your instrument. When Phase 3 is connected to the PC for the first time, Windows
should detect the connection and then automatically launch the New Hardware Wizard which will
prompt you for the USB driver (Figure 101).
Figure 101 - New Hardware Wizard
The USB drivers for Phase 3 are provided with Phase3pc software. When the Hardware Wizard
asks for the files, direct the Hardware Wizard to your CD drive, or to the location where the files
were downloaded. The Wizard should then find and install the required driver files.

NOTE:
During installation of the USB drivers, Windows XP

users may receive a warning message that the driver
has not been "Logo Tested" (Figure 102). Please
ignore this warning and clear the message by clicking
the "Continue Anyway" button.

Figure 104 - Remote Mode menu of Phase 3.

6.3 AutoSequence Editor
When Phase3pc is run for the first time, the program starts up by displaying a library of
AutoSequences which are stored locally on the computer (Figure 105). Each row in the grid
represents one AutoSequence, as identified by a title and the type of device to be tested
(defibrillator/pacer, or AED).
Figure 105 - Phase3pc AutoSequence listing.
An AutoSequence is a sequence of steps which automates the testing of a defibrillator or pacemaker

(see Section 4.10 for further details). Phase3pc can easily create, edit, and organize up to 32
AutoSequences. AutoSequences can then be uploaded from the software to Phase 3 for storage in
the non-volatile memory. Alternatively, AutoSequences stored in Phase 3 can be downloaded into
the software for editing, and then re-uploaded to the instrument. The AutoSequence toolbar of
Phase3pc is shown in Figure 106.

Figure 106 - AutoSequence Editor toolbar.
6.3.1 Creating an AutoSequence
Create a new AutoSequence by clicking New Autosequence on the AutoSequence toolbar, or by

pressing b +N on the keyboard. A new AutoSequence will appear at the bottom of the
AutoSequence grid. This new AutoSequence will be blank, that is, none of the tests provided by the
AutoSequence will be enabled.
6.3.2 Editing an AutoSequence
Edit an AutoSequence by double-clicking an entry in the AutoSequence grid. The AutoSequence

Editor will appear. See Section 6.3.6 for more information.
6.3.3 Copying and Deleting AutoSequences
To copy AutoSequences, select any number of AutoSequences in the grid by dragging the mouse
over them. Then, click Copy AutoSequences, or press b +C on the keyboard. If the
resulting number of AutoSequences is 32 or less, the copied AutoSequences will appear at the
bottom of the grid.
To delete AutoSequences, select any number of AutoSequences in the grid by dragging the mouse
over them. Then, click Delete Autosequences, or press c on the keyboard. A warning will
appear requiring you to confirm the action. Click Yes to delete the AutoSequences.

6.3.4 Uploading and Downloading AutoSequences
AutoSequences can be transferred to Phase 3 via a USB connection. Before attempting to upload or
download, make sure Phase 3 is connected to the PC and that Phase 3 is running in Remote Mode
(see Section 6.2).
To upload AutoSequences into Phase 3, click the Upload Autosequences button, or press
b +U on the keyboard. To download AutoSequences stored in Phase 3 to the PC, click the
Download Autosequences button, or press b +D on the keyboard. In both instances, a
communications progress window will appear. When the transfer has completed, click “OK”.
6.3.5 Printing AutoSequences
Phase3pc allows you to print all the AutoSequences, or a selected number of AutoSequences. To
print one AutoSequence, highlight it in the grid. To print a range of AutoSequences, select the
desired sequences by dragging the mouse over them.
Click Print Autosequences, or press b +P on the keyboard. The Print window will appear.
Choose to print either the selected AutoSequence(s) or all of the AutoSequences, via the radio
buttons which are provided on the Print dialog.
6.3.6 AutoSequence Editor
AutoSequences are comprised of different types of test, including:
• defibrillator energy, charge time, and synchronization delay;

• ECG monitor/chart recorder performance;
• pacemaker pulse, refractory, immunity and sensitivity; and
• AED performance.
Some test types, such as defibrillator energy, can be repeated a number of times with different
configurations for each test. The AutoSequence Editor provides each test type with its own tab. If
the test is a repeatable type, a list box will appear on the left-hand side of the Editor window, with
Add and Delete buttons located below the list (Figure 107). The test options will appear
on the right-hand side of the Editor window.

Figure 107 - Editing defib energy test#5.
To add a new test to the list, press the Add test button below the list box. Select a test in the
list box by clicking on it. The parameters of the selected test will then appear in the text boxes on
the right. Delete a test from the list by selecting the test in the list box and clicking the Delete test
button, or pressing c on the keyboard.
6.3.6.1 Editing the AutoSequence Title
Edit the title of the AutoSequence in the Autosequence Title text field on the top of the
Autosequence Editor. Normally, you would choose a title that represents the make and model of the
defibrillator. The title can be a maximum of 16 characters.

6.3.6.2 Selecting the Device Under Test
To test either a defibrillator and/or transcutaneous pacemaker, select Defibrillator in the Device
Under Test combo box. To test an automated external defibrillator (AED), select AED in the
Device Under Test combo box.
6.3.6.3 Editing Defibrillator Energy Tests
A defibrillator energy test measures the energy delivered by a defibrillator when it is discharged. The
test is normally repeated several times, with the defibrillator set to different energy levels for each
test. In an AutoSequence, each measured energy is compared a target value corresponding to the
energy setting on the defibrillator. The tolerance of the test defines a range of acceptance for the
measured energy. If the measured energy falls within the acceptance range defined by the
AutoSequence settings for target and tolerance, Phase 3 automatically passes the measured energy.
To begin editing defibrillator tests, select the Defib Energy tab (Figure 107). The maximum
number of energy tests than can be performed in an AutoSequence is 10. Add tests if required, via
the button as previously described. Select a test from the list on the left. Enter the Target
Energy for this test (i.e., the energy setting on the defibrillator), and choose a Tolerance. Set up
the Phase 3 ECG simulator for this test by first choosing the simulator Wave Bank, and then
selecting the Wave (waveform). The amplitude scale of the Wave can also be changed by selecting a
value in the Scale combo box.
6.3.6.4 Editing the Charge Time Test
A charge time test measures the time required for a defibrillator to charge up to a specified energy
level, which is typically the maximum energy provided by the device.
To begin editing the charge time test, select the Charge Time tab on the AutoSequence Editor.
An AutoSequence provides only one charge time test. To enable this test, click the Enable
Charge Time Test checkbox. Enter the Target Energy for this test (i.e., the maximum energy
setting on the defibrillator), and choose a Tolerance. Enter an upper limit for the measured charge
time in the Measured Charge Time box. Set up the Phase 3 ECG simulator for this test by first
choosing the simulator Wave Bank, and then selecting the Wave (waveform). The amplitude
scale of the Wave can also be changed by selecting a value in the Scale combo box.

6.3.6.5 Editing Cardioversion Tests
A cardioversion test verifies the ability of a defibrillator to synchronize its discharge to the QRS
complex of the ECG.
To begin editing cardioversion tests, click the Cardioversion tab of the AutoSequence Editor.
When the first cardioversion test is enabled, the ECG simulator will be configured so that it reverts
to normal sinus rhythm when a discharge is detected. If desired, disable this option under the
Advanced tab of the AutoSequence Editor.
The maximum number of cardioversion tests than can be performed in an AutoSequence is 4. Add
tests if required, via the button as previously described. Select a test from the list on the left.
Click the Enable Delay Target checkbox if you want Phase 3 to pass or fail the measured sync
delay. Enter the Target Energy for this test (i.e., the energy setting on the defibrillator), and
choose a Tolerance. Set up the Phase 3 ECG simulator for this test by first choosing the simulator
Wave Bank, and then selecting the Wave (waveform). The amplitude scale of the Wave can also
be changed by selecting a value in the Scale combo box. In the Sync To combo box, select the
timing reference that will be used to measure the synchronization delay (Q or R wave).
6.3.6.6 Editing ECG Performance Tests
An ECG test verifies operation and performance of the monitor and/or chart recorder of a
defibrillator. To begin editing ECG performance tests, click the ECG Performance tab of the
AutoSequence Editor (Figure 108).
Figure 108 - Editing an ECG test.

The maximum number of ECG tests that can be performed in an AutoSequence is 12. Select the
ECG signal amplitude via the Scale combo box; the same amplitude will be used for all waveforms
in the ECG sequence. Set the ECG simulator for each step of the sequence by first choosing the
simulator Wave Bank, and then selecting the Wave (waveform).
6.3.6.7 Editing Pacer Tests
To begin editing pacer tests, click the Pacer tab of the AutoSequence Editor. The pacer sub menu
will appear below the main tab menu (Figure 109). Click on the buttons of the pacer sub menu to
navigate the various pacer tests described in the following sections.
6.3.6.8 Editing the Pacer Load
The pacer load is the load value which will be used by Phase 3 in all pacer tests of an AutoSequence.
Click the up or down arrow to respectively increase or decrease the resistance in 50 ohm increments.
6.3.6.9 Editing Pacer Pulse Tests
A pacer pulse test measures amplitude, rate and width of the pulses generated by a pacemaker
(Figure 109). The maximum number of pulse tests that can be performed in an AutoSequence is 10.
To edit pacer pulse tests, click the "Pacer" tab and then click the "Pulse" button on the pacer sub
menu. Select a test in the list on the left by clicking on it. For the selected test, enter a "Target
Current" and Pulse Rate in the text fields provided on the right. A target for pulse width is
optional, and can be enabled by clicking the checkbox next to the Target Pulse Width text field.

more information on amplitude measuring methods, see Section 4.7.2.

Figure 109 - Editing pacer tests (pulse test).
6.3.6.10 Editing the Noise Immunity Test
A noise immunity test verifies that a pacer will not respond to line frequency noise injected into its
ECG input. An AutoSequence can include only one noise immunity test.
To edit the noise immunity test, click the Pacer tab and then click the Noise Immunity button
on the pacer sub menu. To enable the test, click the Enable Noise Immunity checkbox. Select
the frequency of the noise signal via the Test Type combo box.
6.3.6.11 Editing Demand Sensitivity Tests
A demand sensitivity test determines the smallest ECG signal that will reliably trigger a pacer when
the pacer is operating in demand mode. The maximum number of sensitivity tests that can be
performed in an AutoSequence is two.
To edit the sensitivity test, click the Pacer tab and then click the Demand Sensitivity button on
the pacer sub menu. Select a test in the list on the left by clicking on it. For the selected test, enter a
Sensitivity Limit in the text field provided on the right. This limit is the largest ECG signal that
can be accepted to result in a passing test. Set up the Phase 3 ECG simulator for this test by first
choosing the simulator Wave Bank, and then selecting the Wave (waveform).

6.3.6.12 Editing Refractory Period Tests
A refractory period test determines the two refractory periods of the pacemaker under test. The
paced refractory period (PRP) is the time interval following a pacer pulse during which ECG QRS
complexes are ignored. The sensed refractory period (SRP) is the time interval following a detected
QRS where a subsequent QRS is ignored. The maximum number of refractory tests that can be
performed in an AutoSequence is two.
To edit the refractory test, click the Pacer tab and then click the Refractory Period button on
the pacer sub menu. Select a test in the list on the left by clicking on it. For the selected test, enter
maximum and minimum limits for both PRP and SRP in the text fields provided. Set up the Phase 3
ECG simulator for this test by first choosing the simulator Wave Bank, and then selecting the
Wave (waveform).
6.3.6.13 Editing Advanced Options
The ECG Trigger Mode listbox allows selection of one of four possible responses of the ECG
simulator to a defibrillator discharge. Phase 3 may automatically change its waveform to normal
sinus rhythm when a discharge is detected from the defibrillator under test. Alternatively or in
addition, Phase 3 can play back the discharge waveform into the paddles or ECG leads of the
defibrillator. See section 4.5.1.2 for more details on the MODE settings.
The Auto-Test Timer listbox allows selection of the length of time Phase 3 will wait before
proceeding to the next step in an AutoSequence, where appropriate. The Auto-Test Timer allows
the operator time to read or respond to data or messages on the display screen, and may be turned
OFF if full manual control of the Autosequence is desired. See section (ref 4.10.3.1) for more details
on the Auto-Test Timer.

6.3.6.14 Editing AED Energy Tests
If the device under test is an AED, select "AED" in the Device Under Test combo box at the
top of the AutoSequence Editor. The AED Energy test options will appear, while defibrillator and
pacer test options will be hidden (Figure 110).
The maximum number of energy measurements that can be performed in an AED AutoSequence
is 32. Select a test in the list on the left by clicking on it. Set up the Phase 3 ECG simulator for this
test by first choosing the simulator Wave Bank, and then selecting the Wave (waveform). The
amplitude scale of the Wave can also be changed by selecting a value in the Scale combo box. The
Shockable field displays the expected outcome of the test according to AAMI guidelines (see
Section 4.8).

6.4.3 Saving Test Reports
6.4.3.1 Saving as a Text File
In the Test Report Viewer, Test Reports can be saved in both TXT (Text) and CSV (Comma
Separated Values) formats. To save the viewed Test Report(s) in text format, click the "Save To
Text" button of the Test Report Viewer. A directory browser will appear. Select the directory where
the Test Reports should be saved. A file for each individual Test Report in the Viewer will now be
created, where each file will be automatically assigned a filename according to:
DeviceID.YYYY_MM_DD.hh_mm_ss.txt
Above, DeviceID is the defibrillator ID (equipment control number or other ID), YYYY is the
year, MM is the month, DD is the day, hh is the hour, mm is the minute, and ss is the second in
which the Test Report file was created on the PC.
6.4.3.2 Saving as a CSV File
Saving Test Reports in CSV format produces the same result as saving to text format, except a CSV
file is also created listing each device and a path to the Test Report text file for that device. Each line
of the CSV file thus consists of:
"Device ID", "Test Date and Time", "Test Type", "Device Under Test","Overall Pass",
"Filename and Path of Test Report"
Before creating the CSV file, a save file dialog will appear. Select the desired directory and specify a
name for the CSV file. The CSV file and all corresponding Test Report text files will be saved in the
chosen directory.

6.4.3.3 Saving as a MUP File
To save the viewed Test Reports in Sentinel32 MUP format, select the Save To MUP option
under the File menu of the Test Report Viewer. Select a location and either accept the default
filename which is generated automatically, or enter an alternative filename on the Save dialog. By
default, Phase3pc automatically generates a "medTester-style" filename which is intended to
facilitate direct import into Sentinel32 through the medTester Communication dialog of that
program. The format of the default MUP filename is:
MMDDhhmm.mup
where MM is the month, DD is the day, hh is the hour and mm is the minute in which the MUP file
was created on the PC.
6.4.4 Searching for Test Reports
In the main Test Report window of Phase3pc, there is a search text box in the upper right hand
corner (Figure 114). Use this to filter the downloaded Test Reports by Device ID, Device Under
