Series 2040 Maintenance Manual V2.00 Selftest & Calibration

check the Selftest assembly’s cable for damage.

UUT POWER SUPPLIES OFF - Make sure the UUT Power Supplies

are on.

TESTHEAD POWER SUPPLY FAULT - Check the Testhead Power

Supply Controller’s indicator LEDs. If any of the LEDs are not lit,

reset the system and recheck.

MISALIGNED PINS ON PATCHBOARD RECEIVER - Remove the

Selftest Assembly and carefully inspect the alignment of the

Patchboard receiver pins. Adjust any pins that are misaligned,

remount the Selftest Assembly, and re-test.

After the common problems have been eliminated, a failure in

Functional Selftest can indicate a hardware problem. Since a failure

in Functional Selftest could also be caused by calibration,

recalibrate the unit and run Functional Selftest again. If calibration

or Functional Selftest fails now, a hardware problem most likely

exists. Refer to the Selftest Failure Analysis on the next two pages.
