Self-Test
A power-on self-test occurs automatically when you turn on the
multimeter. This limited test assures you that the multimeter is
operational. This self-test does not perform the extensive set of analog
tests that are included as part of the complete self-test described below.
A complete self-test runs a series of tests and takes approximately
15 seconds to execute. If all tests pass, you can have a high confidence
that the multimeter is operational.
• The results of the complete self-test are stored in internal reading
memory (see page 84). Memory is cleared as the self-test stores this
information. Other than clearing memory, the complete self-test
does not alter the state of the multimeter.
• 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 multimeter to Agilent for service.
• Front-Panel Operation: You can perform some of the tests (complete
self-test) individually or you can perform all tests together at once.
4: TEST (SYS MENU)
Another way to perform the complete front-panel self-test is as follows:
Hold down
Shift as you press the Power switch to turn on the
multimeter; hold down the key for more than 5 seconds. The self-
test will begin when you release the key.
• Remote Interface Operation:
*TST?
Returns “0” if the self-test is successful, or “1” if it fails.
