Troubleshooting
NOTE: This troubleshooting guide describes SDM-2009 problems only. See
the GX-2009 Operator’s Manual for problems you may encounter with
the GX-2009.
Table 3: Troubleshooting the SDM-2009
Symptoms Probable Causes Recommended Action
• Fresh air
adjustment fails
• The SDM-2009 is not in a
fresh air environment or
the cylinder being used is
not a zero air cylinder.
• If a zero air cylinder is
used, the calibration
cylinder is out of gas.
• If a zero air cylinder is
used, the tubing from the
regulator to the AIR fitting
is not connected.
1. Confirm that the SDM-2009 is in
a fresh air environment or that a
zero air cylinder is attached to
the AIR fitting.
2. If a zero air cylinder is used,
verify that it contains an
adequate supply of test sample.
3. If a zero air cylinder is used,
check all calibration tubing for
leaks or for any bad connections.
4. If the fail condition continues,
replace the sensor(s) in the
instrument.
5. If the difficulties continue, contact
RKI Instruments, Inc. for further
instruction.
• Calibration fails • The auto calibration
values do not match the
cylinder gas
concentrations.
• The calibration cylinder is
out of gas or is outdated.
• The calibration cylinder is
not connected to the GAS
fitting.
• The GX-2009 is not
properly inserted in the
instrument cradle.
• The tubing from the
regulator to the GAS fitting
or manifold is not
connected.
1. Confirm that the auto calibration
values match the concentrations
listed on the gas cylinder.
2. Verify that the calibration cylinder
contains an adequate supply of
fresh test sample.
3. Verify that the calibration cylinder
is connected to the GAS fitting.
4. Check to make sure the GX-2009
is properly inserted in the
instrument cradle.
5. Check all calibration tubing for
leaks or for any bad connections.
6. If the fail condition continues,
replace the sensor(s) in the
instrument.
7. If the difficulties continue, contact
