Troubleshooting the Analyzer

To troubleshoot performance test failures

To troubleshoot performance test failures
With the exception of the Quick Confidence test, all functional self tests must pass
before the following table is valid.
Step 1. If the analyzer failed a performance test, compare the failing performance test
to the following table.
If more than one performance test is failing, use the entry that is closest to the
beginning of the table. The table lists the probable faulty assembly or assemblies and
any recommended adjustment or troubleshooting procedure to do before replacing the
assembly. If both an adjustment and a test are recommended, do the adjustment first.
