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 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.
