High Priority Alarms
Symptom/Alarm
1. High NO Alarm
High NO
Possible Cause
Recommended Action
A.Note: A newly installed NO sensor will give high readings until fully conditioned (about 5 hours) and calibrated.
a. After installation of the NO sensor perform a low and high calibration.
B.The High NO alarm level may be
inappropriately set.
a. Make sure the High NO alarm is set greater
than the Set NO value.
C.The NO calibration may have drifted.
a. Perform a low and high range calibration of the NO sensor.
b. Wait 5 hours and repeat both the low and
high calibration.
b. Check calibration sample tee for leaks.
D.Circuit setup incorrect.
a. Check circuit setup for correct use of adapters and/or check valves.
