7-4-6 Probe Select Board Diagnostic Tests (cont’d)
NOTE: The ACW Pre-Mixer Gain Test has one test report. By default, this is displayed in the Reports

7) When done, trackball to the Exit button and press Set to close the View Report window.
8) After reviewing the test results, proceed as follows:
• Re-boot the system (this is obligatory).
• Perform calibration, as described in 7-4-2-1 "DC Offset Calibration" on page 7-27.
• If no problems were identified but the problem persists, contact your local GE HEALTHCARE
field engineer for assistance.
• If “Fail” appears in one of the Result columns, the test has failed, even if “Pass” appears in other
columns. Repeat the ACW Pre-mixer Gain Test.
• If errors were identified and the results were not marginal, 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. Contact your local
GE HEALTHCARE field engineer for assistance.
9.) Trackball to the Exit button and press Set to close the View Test Log dialog box.
