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 pressure 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.
Choose the number of measurements in the average from one to 100.
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 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
to 122 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

Diagnostics
The Dener 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 Dener is operating accurately.
• Invert your Dener and allow the piston to travel to
the top.
• Cap the port under test using the Mesa 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.

3.0 Data Port
3.1 Dener 5V Feature (optional)
Your Dener 220 can be purchased with a 5-volt output that provides a voltage signal proprtional to the ow rate measured. Zero volts represents no
ow and 5 volts corresponds to the Upper Range Flow (URV); a user settable
value that can be set from the maximum ow rate of a particular Dener
model to 10 percent of the maxiumum ow rate for that Dener.
The Upper Range Flow correspondent to 5 V can be set by accessing
SETUP>PREFERENCES>URV.
Cable/adapter part # 100-125 connects to the serial port of the Dener for
easy access to a voltage measurement point and for simultaneous serial
cable connection. Contact Mesa for details.

10.0 Troubleshooting
Mesa is ready to help you with any operational issue you may encounter with your Dener. 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 Dener turn on?
If the Dener will not turn on, verify that the battery has been charged. When connected to the AC
power adapter/charger and power is present a small green indicator light should be visible through the
front viewing window
My Dener won’t respond to push-button commands.
If the Dener fails to respond to push-button commands, you can perform a hard reset of the Dener.
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 Dener connected properly.
Verify that the ow source is connected to the pressure port of your Dener 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.
24
What’s the best way to connect to the lter medium?
When calibrating sampling pumps best results are obtained with the lter medium connected to the
pump and the Dener connected to the inlet side of the lter medium with a short piece of tubing.
Why am I experiencing a temperature increase in my Dener 220?
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
24
taking measurements. If this is not possible, we recommend disconnecting your Dener
from its AC power adapter/charger while taking ow measurements – or to run gas through
your Dener 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 Dener)
• 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 Dener 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 Dener
to no more then .5 meters/20 inches in length.
What is Sensor Factor?
Sensor Factor is a number that multiplies the measured ow to scale the reading for certain types of calibrations. It allows customers to scale a mass ow controller or meter when
calibrated with alternate gases. Care should be exercised to always verify that the scaling
factor is set correctly and we recommend always returning the scaling factor to 1.000 after
completeing a calibration.
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
25
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 stan-
dard temperature and pressure) / Time
