7.Repeat steps 3 through 6 for any other modules in the mainframe.

8.Turn off electronic load, disconnect power supply and continue with rear panel connections.

In Case of Trouble

Error Messages

Electronic load 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. On the front panel, selftest error messages appear as; ERROR <n> where "n" is a number listed in the following table. Some values consist of a number followed by the affected channel. If this occurs, turn the power off and then back on to see if the error persists. If the error message persists, the electronic load requires service. Refer to the list of Agilent Sales and Support Offices at the back of this manual.
