Calibration Checks
To access the Gas Analyzer Calibration window select Gas Analyzer Calibration in the
Setup Gas Analyzer menu.
A Passed/Failed indication is displayed for the Zero and the Span calibrations. Refer
to the table below for possible causes of
Failed indications, and their recommended
corrective actions.
Calibration Checks Troubleshooting Table
Symptom Possible Cause Corrective Action
Zero calibration
shows
Failed/
Agent-ID Zero
Calibration failed.
(Agent-ID Zero
failed is only seen as
INOP in monitoring
mode)
Solenoid or air reference
filter problem.
Check the solenoid while running a Zero
calibration, by feeling whether air is being
pulled in at the room air filter. If not, first
replace the room air filter. If the problem still
persists, replace the solenoid. If Agent-ID zero
calibration failed, check solenoid #2.
Occluded pneumatics
Check for an occlusion, such as bent or
collapsed tubing. Listen for a louder or higher
frequency pump noise. This can indicate that
the pump is working to compensate for an
internal occlusion. Replace watertrap/tubing/
filter, if necessary.
Flowrate problem.
Perform leakage check. If problem still persists,
perform flowrate check.
Flow transducer
incorrectly connected to
flow restrictor
Check that the transducer ports A and B on the
Main PC board are connected to the correct
side of the flow restrictor.
Pump problem
Block the gas inlet port and verify that the
pump is driven harder to compensate for the
reduction in flow. Perform pump test provided
in the Preventative Maintenance kit. Caution:
The instructions on cleaning apply only to the
“old-type” square shaped pump; do not clean
the “new type” round pump. If the pump fails
the test, replace it.
IR measurement head
problem
Check out IR measurement head . Replace if
necessary.
Agent-ID problem
Check out Agent-ID. Replace if necessary.
O
2
Zero calibration
shows
Failed.
Flowrate problem.
Perform leakage check. If problem still persists,
perform flowrate check.
O
2
Span problem Perform a Zero calibration followed by a Span
calibration. Check that the Span calibration is
within the accepted tolerance. If not, repeat the
Zero and Span calibration one more time.
O
2
sensor problem. If calibration still fails, perform the O
2
check for
a defective sensor as described above. If the O
2
check fails, replace the O
2
sensor.
