Process Pressure Checks (only if above 2 PSIG)
Possible Cause Corrective Action
Process Pressure set
incorrectly
To check that you entered the process pressure correctly, select
Process Pressure
from the
Configuration
menu. Also ensure
that the calibration process pressure equals normal operating
process pressure. Calibration should only be performed under
these conditions for highest accuracy.
Cell Checks
Possible Cause Corrective Action
If the Cell fails when you
first begin to use the
analyzer:
It is likely that there is a leak in the analyzer plumbing or an im-
proper calibration gas setup, and there is not a problem with the
Cell itself (see the “Leak Check” section later in this chapter for
help on how to check for leaks; see the “Calibration/Aspirator Air
Setup Checks” section earlier in this chapter for help on checking
your calibration gas setup).
If the analyzer has been
operating for some time
and you feel the oxygen
reading is inaccurate:
First check by running a known calibration gas to verify the ana-
lyzer’s response. If the analyzer responds to the calibration gas
correctly, it indicates either leaking or plugged plumbing.
If your analyzer doesn’t
respond properly to the
calibration gas:
This may indicate a problem with the Cell. Before replacing the
Cell, check for leaks or plugged plumbing.
