Self-Test
A brief power-on self-test occurs automatically whenever you turn on
the instrument. This limited test assures that the instrument is capable
of operation and also checks the plug-in cards for basic operation.
To perform a complete self-test hold down the key as you press
the power switch to turn on the instrument; hold down the key
for more than 5 seconds until the instrument beeps (a complete
description of these tests can be found in chapter 6). The instrument
will automatically perform the complete self-test procedure when you
release the key. The self-test will complete in approximately 20 seconds.
• If the 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. If repair is required, see chapter 6,
“Service,” for further details.
• If all tests pass, you have a high confidence (~90%) that the
instrument is operational.
