System-Related Operations

This section gives information on topics such as self-test, error conditions, and front-

Self-Test

A power-on self-test occurs automatically when you turn on the power supply. This

• A complete self-test performs a series of tests and takes approximately 2 seconds to
execute. If all tests pass, you can have a high confidence that the power supply is
operational.

self-test fails, "FAIL" is displayed and the ERROR annunciator turns on. See the
Service Guide for instructions on returning the power supply to Agilent Technologies
for service.
