System-Related Operations

This section gives information on topics such as self-test, error conditions, and front-panel display control. This information is not directly related to setting up the power supply but is an important part of operating the power supply.

Self-Test

A power-on self-test occurs automatically when you turn on the power supply. This test assures you that the power supply is operational. This test does not perform the extensive set of tests that are included as part of the complete self- test described below. If the power-on self-test fails, the ERROR annunciator turns on.

•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.

•If the complete self-test is successful, “PASS” is displayed on the front panel. If the 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.

•Front-panel operation:

The complete self-test is enabled by pressing the Recall the(actually any front panel keys except the Error key) and the power-line switch simultaneously and then continuing to press the Recall key for 5 seconds. The complete self- test will be finished in 2 seconds.

•Remote interface operation:

*TST?

Returns “0” if the complete self-test passes or “1” if it fails.
