16 Keysight E36200 Series Service Guide
Troubleshooting
Before troubleshooting or repairing the instrument, make sure the failure is in the
instrument rather than any external connections. Also make sure that the
instrument was accurately calibrated within the last year (see “Calibration
Adjustment Procedures” on page 82 and “Calibration interval” on page 82 for
details).
Perform the following verifications if the unit is inoperative:
– Verify that the ac power cord is connected to the power supply.
– Verify that the front-panel power switch is depressed.
Self-Test Procedures
A power-on self-test occurs automatically when you turn on the power supply.
This limited test assures you that the power supply is operational.
Refer to the E36200 Series User’s Guide for more information on how to run a
complete self-test of the power supply (Chapter 2, “General Operating
Information” > Utilities Menu - Test/Setup > Self-Test).
Replacing the Fuse
The fuse is located within the power supply's fuse-holder assembly on the rear
panel. Refer to the E36200 Series User’s Guide for more information on how to
replace a faulty or blown fuse (Chapter 1, “Product Information” > Fuse
Information).
