Step 4. Run the remaining self tests.
•
Connect the rear panel SOURCE output to the rear panel TACH input
using a BNC cable.
•
Remove all cables from the front panel input connectors.
Caution The ICP self test outputs approximately 30 Vdc on the input connectors. Before
starting the self tests, disconnect all devices connected to the input connectors.
Devices left connected during the ICP self test may be damaged.

A failure may cause the self tests to run very slow. If the analyzer does not
complete a self test within a few minutes (analyzer locks up during the test),
consider it equivalent to displaying FAILS in the test log.
•
If any of these self tests fail, locate the test that failed in the ‘’Self-Test
Troubleshooting Guide’’ on page 4-33.
•
If the failure still is not isolated, go to page 4-45, ‘’To troubleshoot source
and calibrator failures.’’
