Alert Description and Suggested Corrective Action
Filter Verification Fail
This alert can occur if the light intensity has dropped below acceptable
levels.
Corrective Action:
Take appropriate safety precautions to power down the analyzer, open
the Electronics Enclosure, and:
•
Check the glass filter to confirm it is clean and free of scratches. If
not, wipe lightly with a soft material and IPA or acetone. If scratched,
contact AMETEK Service for assistance.
•
Confirm Cell Windows and Mirrors are clean. If not clean them as
described in Chapter 5.
•
If the Cell has an absorbing gas or particulates present, confirm the
Zero gas is clean and pure.
•
Note the light intensity during a Zero gas routine. If low, the lamp may
need to be replaced.
•
If the problem is suspected or found to be caused by Bad Wavelength
Mapping, contact AMETEK Service for assistance.
