11) After reviewing the test results, proceed as follows:
• If no problems were identified, it is recommended to re-boot the system (this is obligatory when
prompted).
• If the test passed but the original problem persists, contact your local On-Line Center for
assistance.
• If errors were identified but the results were very close to the upper or lower limits, perform
calibration, as described in "DC Offset Calibration" on page 7-25 , and then repeat the test.
• If errors were identified (results exceeding acceptable upper or lower limits), verify that all
system cables and boards are connected (not misplaced) and functioning properly, as
described in
Chapter 5 - Components and Function (Theory) .
If the problem persists, this indicates that either the specific board you tested is faulty or that
another board that supports the operation of that board is faulty. Continue trouble-shooting
down to the appropriate board. (If necessary, perform a specific test).
If the problem still persists, contact the GE On-Line Center for assistance.
