Readings
Choose the ow reading type to either volumetric ‘Vol’ or standardized ‘Std’. Volumetric
ow is the actual ow at the ambient temperature and pressure whereas the standardized ow indicates a ow rate at a specic temperature and pressure. Standardizing pres-
sure is set to a default value of 760 mmHg whereas standardizing temperature is an user
settable value set at ‘Std To’ in the ‘Units’ sub-menu.
Choose the number of measurements in the average from 1 to 100.
If you wish to incorporate a time delay between consecutive measurements, set Time
Between from 1 to 60 minutes.
Set the Sensor Factor to any value between 0.200 to 3.000. Sensor factor scales the read-
ing for calibrating MFCs and MFMs with surrogate gases. Sensor factor affects the ow
rate measurement only when the reading ‘Type’ is set to standardized ‘Std’.
9
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
to122 deg F. ‘Std To’ effects the ow 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)-

Diagnostics
The Defender 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 whenever the integrity of the instrument is questioned due
to misuse or accidental damage.
Please note that a leak test is not a substitute for a
comprehensive examination of the unit’s overall performance and it does not ensure that your Defender is
operating accurately.
• Invert your Defender and allow the piston to travel to
the top.
• Cap the port under test using the supplied leak test
cap. Leave the other port uncapped.
• Press Enter on the control panel while the unit is still
inverted.
• Return the unit upright. The leak test will progress.

10.0 Troubleshooting
Answers to common operational questions
Mesa is ready to help you with any operational issue you may encounter with your Defender. 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.
Why won’t my Defender turn on?
If the Defender will not turn on, verify that the battery has been charged. When connect-
ed to the AC power adapter/charger and power is present a small green indicator light
should be visible through the front viewing window
My Defender won’t respond to push-button commands.
If the Defender fails to respond to push-button commands, you can perform a hard reset
of the Defender. This can be done by inserting a paper clip into the reset opening in the
back of the unit.
I’m not sure I have my Defender connected properly.
Verify that the ow source is connected to the pressure port of your Defender for pressure sources or to the suction port for verifying suction pumps. The unused port should
be at atmospheric pressure with any cap or plug removed. If you are calibrating a gas
that requires an exhaust line to vent the measurement gas, ensure that the tubing is of
sufcient diameter not to create a pressure drop greater then 5 inches of water.
How do I protect against leaks?
Ensure that hose and tube ttings are tight and leak free. The tubing connecting your
ow source (pump, mass ow controller, needle valve, sonic nozzle or restrictor) to the
meter should be kept as short as possible.
What do I do when my leak test fails?
First check to make sure that the leak test cap is on correctly and it is not leaking
through the leak test cap itself. If the leak test cap is correct perform leak test both at
the pressure and suction side. If it fails, contact Mesa Technical Support.
What’s the best way to connect to the lter medium?
25
When calibrating sampling pumps best results are obtained with the lter medium connected to the pump and the Defender connected to the inlet side of the lter medium
with a short piece of tubing.
25
Why am I experiencing a temperature increase in my Defender 530?
A temperature rise during initial battery charging, or while charging a fully
discharged battery is normal. To maintain the best possible accuracy Mesa
recommends fully charging your battery before taking measurements. If this is
not possible, we recommend disconnecting your Defender from its AC power
adapter/charger while taking ow measurements – or to run gas through your
Defender for 10 minutes before starting the ow measurement.
Why doesn’t my piston return to the bottom of the cell?
If the piston fails to return to the bottom of the cell after a measurement this
could be caused by:
• A discharged battery not providing enough power to operate the internal
valve properly (Try charging the Defender)
• 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 Defender to Mesa for service)
What is dead volume?
Dead volume is the gas volume between a ow generator and the instrument
taking the measurement. Since gas is compressible, this gas can act as a
spring between the ow source and the measurement instrument. For best accuracy, this volume should be kept to a minimum. We recommend keeping the
tubing length between the gas ow generator and your Defender to no more
than 0.5 meters/20 inches in length.
What is the difference between volumetric ow and
standardized ow?
As we know from the ideal gas law, the volume of a gas changes with a
change in temperature or pressure even when the number of molecules which
constitute the mass remains the same.
Volumetric ow rate is the rate at which a volume of a gas travels past a given
26
10.0
location. Volumetric Flow= As Measured Volume of Gas / Time
Standardized (mass) ow rate is expressed as the rate at which the volume
of a gas travels past a given location if the gas is at a specied temperature
and pressure. From the ideal gas law if the temperature and pressure are held
constant, the volume of the gas is proportional to the number of molecules.
Standardized Flow= Volume of Gas (at the standard
temperature and pressure) / Time
