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 two 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
(E3632- 90010)
for instructions on returning the power
supply to Keysight for service.
Front panel operation
The complete self- test is enabled by pressing
(actually any front panel keys except
) and the
power- line switch simultaneously and then continuing to
press
for five seconds. The complete self- test will be
finished in two seconds.
