12) 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 - Components and Function (Theory).
