•
If the self tests fail but do not lockup the analyzer, note the failure messages
and go to Step 2.
•
If the analyzer locks up on the Quick Confidence self test but not on the
input self tests, note the failure messages and go to Step 2 but don’t run the
Quick Confidence self test.
•
If the analyzer locks up on the input self tests, go to Step 2 to determine if
exchanging the Input assemblies will allow the self tests to run.
This is most likely to occur when channel 1 and 3 are failing.
•
If the self tests pass, go to Step 2 but substitute the failure symptom for the
self tests.
If the exact failure symptom is not known, use the performance test procedures to
isolate the failure symptom.
