In Case of Trouble

Error Messages

Dc source failure may occur during power-on selftest or during operation. In either case, the display may show an error message that indicates the reason for the failure.

Selftest Errors

Pressing the Shift, Error keys will show the error number. Selftest error messages appear as: ERROR <n> where "n" is a number listed in the following table. If this occurs, turn the power off and then back on to see if the error persists. If the error message persists, the dc source requires service.

Runtime Error Messages

Appendix C lists other error messages that may appear at runtime. If the front panel display shows OVLD , this indicates that the output voltage or current is beyond the range of the meter readback

circuit. If the front panel display indicates -- -- -- -- -- --

, an HP-IB measurement is in progress.

Line Fuse

 

If the dc source appears "dead" with a blank display and the fan not running, check your power source to be certain line voltage is being supplied to the dc source. If the power source is normal, the dc source fuse may be defective.

1.Turn off the front panel power switch and unplug the power cord.

2.Remove the fuse from the rear panel.

3.If the fuse is defective, replace it with a fuse of the same type (see "Input Connections" in chapter 3).

4.Turn on the dc source and check the operation.

NOTE: If the dc source has a defective fuse, replace it only once. If it fails again, the dc source requires service.
