Introduction
This section provides performance test, troubleshooting information, and
adjustment and calibration procedures. The following operation verification tests
comprise a short procedure to verify that the power supply is performing properly,
without testing all specified parameters.
If a fault is detected in the power supply while making the performance check or
during normal operation, proceed to the troubleshooting procedures. After
troubleshooting, perform any necessary adjustments and calibrations. Before
returning the power supply to normal operation, repeat the performance check to
ensure that the fault has been properly corrected and that no other faults exist.
Test equipment required
The following Table 5-1 lists the equipment required to perform the various
procedures described in this section.
