In Case of Trouble

Error Messages

Ac 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 and 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 ac source requires service.

Runtime Error Messages

Under unusual operating conditions, the front panel display may show OVLD. This indicates that the output voltage or current is beyond the range of the meter readback circuit. If the front panel display indicates ------------ , a GPIB measurement is in progress. Appendix C lists other error messages that may appear at runtime.

Line Fuse

If the ac source appears "dead" with a blank display and the fan not running, first check your power source to be certain line voltage is being supplied to the ac source. If the power source is normal, the ac source line fuse may be defective. If the ac source has a defective fuse, replace it only once. If it fails again, investigate the reason for the failure. Proceed as follows:

1.Turn off the front panel power switch and remove the input power (unplug the power cord or open the safety disconnect).

2.Remove the fuse cover from the rear panel.

3.Unscrew the fuse caps and remove the fuses.

4.If any fuses are defective, replace all three with fuses of the same type (see Chapter 1).

5.Turn on the ac source and check the operation. If it is normal. replace the fuse cover.

Maintenance Note: It is recommended that new fuses be installed every four years.
