Hardware Related Troubleshooting Strategy
Overall troubleshooting strategy for hardware related problems/hardware and measurement related
AGM INOPs:
1 Always perform a leak and flowrate check (see Chapter ) before continuing any other
troubleshooting. If any check fails, first fix leak and/or flowrate problem and repeat a zero
calibration. Then check whether problems still exist.
There are only two device conditions that make it impossible to perform a leak/flowrate check:
– Pump is not running:
Check for proper electrical connection and check that AGM is not in Standby Mode. If OK,
replace pump.
– INOP "GAS AN. EQUIP MALF": see “INOPs” on page 210.
2 After the first zero calibration, always check which AGM INOP’s are displayed in Monitoring
Mode. Refer to “INOPs” on page 210 where you can find a listing of possible root causes and their
corrective actions to the most common hardware and measurement related AGM INOP’s. Check
out the possible problems in the order given in the table!
3 After the first zero calibration, always check which problems are flagged in the Gas Analyzer
Diagnostic window. Troubleshoot flagged problems in the Gas Analyzer Diagnostic window
following the hierarchy given in “Problem Solving Hierarchy” on page 215 and the related
troubleshooting tables and/or troubleshoot zero calibration failures.
