Operating Checklist
Before returning your multimeter to Agilent for service or repair, check
the following items:
Is the multimeter inoperative?
Verify that the ac power cord is connected to the multimeter.
Verify that the front-panel Power switch is depressed.
Verify that the power-line fuse is good.
Verify the power-line voltage setting.
See “To Prepare the Multimeter for Use” on page 29.
Does the multimeter fail self-test?
Verify that the correct power-line voltage is selected.
See “To Prepare the Multimeter for Use” on page 29.
Remove all measurement connections to the multimeter.
Ensure that all measurement terminal connections (both front
and rear terminals) are removed while the self-test is performed.
Errors may be induced by ac signals present on the multimeter
input terminals during self-test. Long test leads can act as an
antenna causing pick-up of ac signals.
Is the multimeter’s current input inoperative?
Verify that the rear panel 3 A, 250 V current fuse is functional.
Verify that the internal 7 A, 250 V high-interrupt fuse is functional.
See “To Replace the Current Input Fuses” on page 115.
