Note: For more information on the features listed in this section please contact your
equipment supplier.
The event log can only be viewed via the optional Analyser Data Manager software. It
cannot be viewed on the analyser screen. Applicable events are stored in the event log
automatically. No user intervention is required.
The event log can hold approximately 270 events. If the log becomes full then it begins
to over-write the older events. This can be identified by the index field which starts from
event number 1. The log is cleared when the instrument is reset.
Note: Please refer to section 12.0 Event Log of this operating manual for further
information.
The display can also be changed to show a T1 T2 calculation by pressing the appropriate
soft-key. The current mode of operation can be identified by normal or inverse status of
the soft-key, where inverse indicates that the option is active.
The operator can also choose to display the reading in either Centigrade or Fahrenheit
using the temperature option accessed from the Settings menu.

When a humidity probe is fitted, the display will change automatically to show the
current reading and a humidity probe icon will be displayed. The Scroll keys on the
instrument panel are used to switch between the reading screens.
Humidity lead
Humidity sensor
Plug the humidity sensor onto the mating connector of the transmitter or connection
cable. Make sure that the catches are aligned correctly. Tighten the knurled nut by
hand.
Note: The humidity sensor can take 30 minutes to stabilise and special handling is
required for optimum performance and stability. Please refer to the instruction
leaflet included with the humidity sensor packaging for the Humidity Standards.
Note: Oxygen sensor stability; as the sensor is a partial pressure sensor its output
will be affected by changes in relative humidity. Although the percentage of O2
in the air is relatively constant, the relative humidity in air is variable. A unit
calibrated with dry air could cause the readout to read low by up to 0.5% by
volume.

Gas Measurement Process
(G100 - Best Practice)
The following method is considered best practice and when followed correctly will allow
quick and consistent readings to be recorded.
1) When the instrument is first switched on it should be purged with fresh air and
allowed to stabilise for a few minutes.
2) At this point it is good practice to verify the CO2 channel. Calibrate only if required.
This option is available via the Calibration menu.
The instrument is now ready to take the first reading.
3) Connect the sample tube, if relevant (always use the sample filter) from the sample
point to the inlet port of the instrument, ensuring the filter is seated correctly.
4) Press the Pump key to draw a sample into the instrument.
Notice the main gas readings start to change. It is recommended to run the pump
until the gas readings have stabilised (approx. 30 seconds) then press the soft-key
Store.
5) The pump will stop and the operator will be prompted to enter an ID code to identify
the reading. A reading stored confirmation message will be displayed briefly before
returning to the Main Read Screen.
Note: The ID code prompt can be switched on or off. This option is accessed via
the Settings menu, then press Key 1 - Prompt for ID: Yes or No. If the
ID prompt is set to No the reading is stored using the default logging ID.
6) After each reading the instrument should be purged with fresh air.
Copyright Page 27
OMG100UB1.21 G100 Range
7) Disconnect the sample tube from the instrument. Then, run the pump for a minimum
of 30 seconds. The gas readings should return to nominal values for fresh air.
Regardless of the instrument configuration the following data will be stored for each
reading:-
ID code (8 characters)
Reading Type (0=User, 1=Auto, 2=peak, 3=hold)
Current time/date
Gas readings (CO2, O2)
Sample pressure (for indication only)
Temperature x 2
Humidity
Logged reading
Peak reading
Hold reading
These parameters are used to control the reading frequency in logging mode. Once
logging mode is activated the instrument will automatically record a reading at every
interval until stopped by the operator or the memory becomes full. Logging is also
suspended temporarily whilst the user is accessing the menu options.
Whilst the logging mode is active the Hold, Pump and Store key will be deactivated,
only logged readings can be stored.
The peak value is reset after a reading is stored or by exiting the peak mode using the
appropriate soft-key. The current mode of operation can be identified by the status of
the soft-key, either Normal or Inverse, where inverse indicates peak mode is active.

7.0 Calibration
This section sets out the correct procedures to achieve an accurate user calibration.
Note: If the calibration is completed incorrectly it may decrease the accuracy of the
instrument.
Two important terms that are used within this section are Zero and Span.
Zero: The point at which the instrument is calibrated when there is none of the target
gas present.
Span: The point at which the instrument is calibrated when a known quantity of the
target gas is present.
Warning For each gas used the appropriate material safety data sheet
must be read and understood before proceeding. Calibration
gases and the use of pressure regulators can be dangerous.
Page 30 Copyright
G100 Range OMG100UB1.21
The regulator supplied with the calibration kit is recommended as flow and pressure
rates are factory set.
To achieve the processes set out in this section, press Key 3 Calibration from the Main
menu. The first screen displayed provides the option to select the gas that requires
calibration.

G100 Range OMG100UB1.21
This section outlines various warning and error messages which the operator may receive
during general operation of the instrument. For further assistance please contact your
equipment supplier.
Use the Scroll Up and Scroll Down keys to move through the list if required.
General warnings that may not affect the instruments function and those where the
self-test has detected a function that is outside the usual operating criteria, e.g.
battery charge low, memory nearly full.
Operational parameters that could affect the performance of the instrument, e.g. CO2
out of calibration.
The most likely reason for these errors is either an incorrect user calibration, or may
indicate sensor failure. If an incorrect user calibration has caused the warning it should be
correctable by way of returning the instrument to factory settings, zeroing or carrying out
a user calibration as necessary for the relevant function.
If a reading is over range (i.e. above the maximum allowed reading) it will be displayed
with more than chevrons (>>.>). This can occur if a channel has been incorrectly
calibrated or the sample gas has exceeded its specified range (e.g. CO2 > 20%).
If a reading is under range (i.e. below zero) it will be displayed with less than chevrons
(<<. <). Refer to section 7.0 Calibration of this manual to remedy under-range by
performing a user zero.
A number displayed as asterisks (**.*) indicates an error, usually where the instrument
has been unable to complete a particular calculation. Typically, this will be the first
indication of a fault condition.
Where no data is available dashes (--.-) are displayed. This usually occurs when a
particular reading or parameter has been skipped by the user, or where an optional
accessory is not fitted correctly, i.e. a temperature probe.
Copyright Page 35
OMG100UB1.21 G100 Range
The following warnings may be displayed during the self-test period when the instrument
is switched ON.
Warning Description
Check Memory The instrument only has space to store less than 50 readings
before it is full. The exact number can be checked using the
View Readings option.
Memory Full There is no more space in memory to store readings. Both the
store and log options will be disabled until the memory is
cleared. The readings should be downloaded to PC using the
optional download software before memory is cleared.
Battery Low The instrument does not have enough power to operate for a full
day. The instrument should be recharged or connected to an
external power supply.
Service Due It has been 12 months (or more) since your instrument was
returned to the manufacturer for a service. The performance and
accuracy of the instrument may be impaired.
Ref. Fault This may be caused by dirt or damage to the infrared sensor in
the instrument. The instrument will need to be returned to the
manufacturer for service/repair.
Change O2 The oxygen cell has not been changed for at least 3 years; its
Cell performance and accuracy may be impaired. The instrument will
need to be returned to the manufacturer for service.
Page 36 Copyright
G100 Range OMG100UB1.21
Warning Description
Change Pump The pump has exceeded its recommended run-time and should
be changed. The instrument will need to be returned to the
manufacturer for service.
Change The Lithium Ion battery has exceeded its recommended life-time
Battery or number of charge cycles and should be changed. The
instrument will need to be returned to the manufacturer for
service.
User Cal. Due It has been over a month since the instrument was last user
calibrated. For optimal performance and accuracy it is
recommended that the instrument is user calibrated each time it
is used.
Invalid Time The instrument has an invalid time. This is most likely to occur
after a reset. The correct time should be entered using the set
Time & Date option via the Utilities menu.
Invalid Date The instrument has an invalid date. This is most likely to occur
after a reset. The correct date should be entered using the set
Time & Date option via the Utilities menu.
Baro. Fault The instrument has detected a fault with the barometric sensor
or its calibration. This will have an effect on the accuracy of the
readings as they are pressure compensated. The instrument will
need to be returned to the manufacturer for service.
Note: *Certain configuration problems can be corrected remotely. Using the Analyser
Data Manager software, it is possible to export the current configuration and e-
mail it to the manufacturers Technical Support or Service Department.
Depending on the type of error it may be possible to correct the configuration file
and import it back into the instrument.
Error Remedy
User Zero failed A possible reason for this is because the instrument is trying to
zero to a level which is outside the predetermined range set when
the unit was calibrated at the factory or; the gas is not stable i.e.
is still flushing the measure gas or is using ambient air/gas that is
varying in concentration. To rectify this, first ensure the unit
contains absolutely none of the gas which is being zeroed by
flushing thoroughly with nitrogen. If it will not zero, then refer to
the instructions given in the Factory Settings section. If the
instrument continues to fail to zero then the unit must be returned
to the manufacturer for investigation.
Calibration failed Check the span target is set to the correct value, if not, correct
and retry spanning the channel. Repeat the entire procedure,
including zeroing the channel and then calibrate the span. Ensure
the reading is stable before spanning the channel.

User calibration is a means of optimising the performance of the instrument to the current
operating conditions such as ambient temperature and pressure as well as correcting for
instrument drift caused by lamp and filter settling.
In general, the instrument should not require calibration more than once a month, but we
do recommend verifying the instruments operation each day.
User calibration has two operations and each may be performed individually, however for a
complete user calibration both must be completed.
Note: The Zero calibration is very sensitive and even 100% instruments will detect in
the 0 to 100ppm range even though they do not display to this resolution. Please
refer to the chart Typical Zero Gas Purge Time.

Note: If using G110 very high concentrations of CO2 may take up to 30 minutes to
purge completely.

WEEE COMPLIANT
The wheelie bin symbol now displayed on equipment supplied signifies that the apparatus
must not be disposed of through the normal municipal waste stream but through a registered
recycling scheme.
The Waste Electrical and Electronic Equipment directive (WEEE) makes producers responsible
from July 1st 2007 in meeting their obligations, with the fundamental aim of reducing the
environmental impact of electrical and electronic equipment at the end of its life.
The OEM is now registered with the Environmental Agency as a producer and has joined a
recycling scheme provider who will manage and report on our electrical waste on our behalf.
So when your instrument is at the end of its life, please contact your equipment supplier who
will advise you on the next step in order to help us meet our obligations.
