2 Connect the power cord and turn the meter on.
The front panel display will light up while the meter performs its power-on
self-test. The GPIB bus address is displayed. The meter is left in 61/2 digit
resolution, channel 1 input, and digital filter on.
To view the display with all annunciators turned on, hold down as you
turn on the meter.
3 Perform a complete self-test.
The complete self-test performs a more extensive series of tests than those
performed at power-on. Hold down Shift as you press the power switch to turn
on the meter; continue to hold for more than 5 seconds. The self-test will
begin when you release the key.
If the self-test is successful, “PASS” is displayed on the front panel. If the test is
not successful, “FAIL” is displayed and the ERROR annunciator turns on. See
the Service Guide for instructions on returning the meter to Keysight
Technologies for service.
