Troubleshooting
NOTE: This troubleshooting guide describes SDM-E2 problems only. See the
EAGLE 2 Operator’s Manual for problems you may encounter with the
EAGLE 2.
Table 5: Troubleshooting the SDM-E2
Symptoms Probable Causes Recommended Action
• Fresh air
adjustment fails
• The SDM-E2 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 gas out to
EAGLE 2 line is not
connected to the inlet of
the EAGLE 2.
1. Confirm that the SDM-E2 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 gas out
to EAGLE 2 line is connected to
the inlet of the EAGLE 2.
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 sensor(s) in the
EAGLE 2.
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out of gas or is outdated.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 1 or
GAS 2 fitting.
• The gas out to EAGLE 2
line is not connected to
the inlet of the EAGLE 2.
• The tubing from the
regulator to the GAS 1 or
GAS 2 fitting 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 appropriate
GAS 1 or GAS 2 fitting.
4. Check to make sure the gas out
to EAGLE 2 line is connected to
the inlet of the EAGLE 2.
5. Check all calibration tubing for
leaks or for any bad connections.
6. If the fail condition continues,
replace the sensor(s) in the
EAGLE 2.
7. If the difficulties continue, contact
RKI Instruments, Inc. for further
