NOTE:
This troubleshooting guide describes SDM-6000 problems only. See
the GX-6000 Operator’s Manual for problems you may encounter with
the GX-6000.
Table 14: Troubleshooting the SDM-6000
Symptoms
Probable Causes
Recommended Action
Fresh air adjust
-
ment fails
• The SDM-6000 is not in a
fresh air environment or
the cylinder connected to
the AIR fitting 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 red gas in/gas
out cover is not pushed
down and engaged with
the GX-6000.
1. Confirm that the SDM-6000 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. Check to make sure the red gas
in/gas out cover is pushed down
and engaged with the GX-6000.
4. If a zero air cylinder is used,
check all calibration tubing for
leaks or for any bad connections.
5. If the fail condition continues,
replace the failed sensor(s) in the
GX-6000.
6. 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out of gas or is outdated.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
appropriate gas inlet
fitting.
• The red gas in/gas out
cover is not pushed down
and engaged with the
GX-6000.
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 appropriate
gas inlet fitting.
4. Check to make sure the red gas
in/gas out cover is pushed down
and engaged with the GX-6000.
5. Check all calibration tubing for
leaks or for any bad connections.
6. If the fail condition continues,
replace the failed sensor(s) in the
GX-6000.
7. If the difficulties continue, contact
RKI Instruments, Inc. for further
instruction.
