There are three failure modes that the analyzer might encounter: General Failure, Zero Failure, and
Failure to Calibrate.
For a General Failure and Zero Failure, perform the following procedure:
1.
Verify that all the back panel ports are unobstructed, including:
-
Cal gas
-
Zero
-
Sample hose
-
Drain hose
2.
Check the sample conditioner filters and pneumatics.
3.
If a failure is still indicated, service is required by an authorized Infrared Industries service center.
For a Failure to Calibrate, perform the following procedure:
1.
Repeat calibration.
2.
If the analyzer still fails to be calibrated, the analyzer can still be used but it will be at reduced accuracy. It
should be sent in for service when convenient.
When the default cal values are in use, the analyzer can still be used but the displayed values will be
less accurate. It is recommended that the gas calibration procedure be performed to ensure accuracy.
SYMPTOM
PROBABLE CAUSE
SOLUTION
Low sample flow
1. Restrictions in sample hose or
probe
2. Restrictions in sample filter
1. Check for kinked, plugged or pinched hose or
probe. Clean probe tip with a small pointed
tool. Disconnect hose from sample inlet and
clean out if necessary
2. Change filter elements
Low sample flow
during zeroing.
Restriction in Zero port
Low zero gas pressure
Check for obstructions in zero port on the back of
the analyzer. (Zero port is under the CAL port)
No output to PC
1.
No compatible program
running on the PC. Please
