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 complet e 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 key (actually
any front panel keys except the key) and the power-line switch
simultaneously and then continuing to press the key for 5
seconds. The complete self-test will be finished in 2 more seconds.
• Remote interface operation:
*TST?
Returns “0” if the complete self-test passes or “1” if it fails.
