Readings
Choose the flow reading type to either volumetric ‘Vol’ or standardized ‘Std’. Volumetric
flow is the actual flow at the ambient temperature and pressure whereas the standard-
ized flow indicates a flow rate at a specific temperature and pressure. Standardizing pres-
sure is set to a default value of 760 mmHg whearas standardizing temperature is a user
settable value set in ‘Std To’ in the ‘Units’ sub-menu.
If you wish to incorporate a time delay between consecutive measurements, set Time
Between from one to 60 minutes.
Set the Sensor Factor to any value from 0.200 to 3.000. Sensor factor scales the reading
for calibrating MFCs and MFMs with surrogate gases. Sensor factor effects the flow rate
measurement only when the reading ‘Type’ is set to standardized ‘Std’.
9
Units
Measure gas Flow in cubic centimeters, milliliters, liters or cubic feet (all units are per
minute).
Measure Pressure in mmHg, kPa or PSI and Temperature in Celsius or Fahrenheit.
Set the standardizing temperature by setting ‘Std To’ to a value from 0 to 50 deg C or 32
to 122 deg F. ‘Std To’ effects the flow rate measurement only when the reading ‘Type’ in
the ‘Reading’ sub-menu is set to standardized ‘Std’.
Time
Set the current time and the format.
The format can be selected as PM, AM, or 24H.
Date
Set the date and the format.
The format can be selected as DD (day)-MM (month)-YYYY (year) or MM (month)-
DD (day)-YYYY (year).
Preferences 10
Read Default
Allows you to select a preferred mode of measurement when the Definer is initially turned
on.
Default Settings
Select <No> to allow the ‘Read Default’ change. Selecting <Yes> will reset your Definer
to the factory default settings. (Factory default settings are provided elsewhere in this
manual.)

ments in larger font, or select <Detail> to simultaneously view flow measurements, tem-
perature, and pressure in a smaller font.
Power
Power Save
By selecting <On>, your Definer will save power by turning off after five minutes of inac-
tivity. However, it will not turn off when connected to the AC power adapter/charger.
Select <Off>, and your Definer will remain on until you manually turn it off.
Backlight
Select <On> to illuminate the LCD display or <Off > to conserve battery power.

Diagnostics
The Definer Leak Test is designed only to verify the
internal integrity of the instrument and alert you to an
internal leak. We recommend performing the Leak Test
only as an intermediate quality control check or when-
ever the integrity of the instrument is questioned due
to misuse or accidental damage.

warning appears. Immediately lower or disconnect the flow. When the flow is within the
proper range, select RESET to clear your Definer’s last measurement.
2.7 Measurements
Taking gas flow readings
To maintain the best possible accuracy and minimize thermal effects, Mesa Labs recom-
mends fully charging your battery before taking measurements. If this is not possible, we
recommend disconnecting your Definer from its AC power adapter/charger while taking
flow measurements — or to run gas through your Definer for 10 minutes before starting
the flow measurement.

10.0 Troubleshooting
Mesa is ready to help you with any operational issue you may encounter with your Definer. But we may
be able to save you some time by providing a short checklist of the questions most commonly asked of
our customer service and technical specialists.
• A discharged battery not providing enough power to operate the internal valve properly
(Try charging the Definer)
• Bright light shining into the unit resulting in an overload of the internal optical sensors
(Try to operate the unit in a shaded location)
• Moisture or dirt inside the cell (Return the Definer to Mesa for service)
We recommend keeping the tubing length between the gas flow generator and your Definer
to no more then .5 meters/20 inches in length.
Standardized (mass) flow rate is expressed as the rate at which the volume of a gas travels
past a given location if the gas is at a specified temperature and pressure. From the ideal
gas law if the temperature and pressure are held constant, the volume of the gas is propor-
tional to the number of molecules. Standardized Flow = Volume of Gas (at the stan-
dard temperature and pressure) / Time
