Front Panel Calibration Procedure

These procedures assume you understand how to operate front panel keys (see chapter 5). Make sure the
sense switch is set to Remote and the sense terminals are directly jumpered to the output terminals.
Calibration procedures can only be performed with the dc source set to the SCPI programming language.

Check the Language Setting

Action

Normal Result

1.

Turn on the dc source, access the Address menu and scroll to the LANG:
command.

LANG: SCPI or

LANG:COMP

2.

If the language is set to COMPatibility, change it to SCPI and press Enter. If the
language is already set to SCPI, just continue with the calibration procedure.

LANG: SCPI

3.

Reset the unit by selecting

4.

Press

5.

To begin calibration press

Shift Cal

, scroll to CAL ON and press

Enter

.

CAL ON 0.0

6.

Enter the calibration password from Entry keypad and press

Enter

. lf the

password is correct the Cal annunciator will come on.
If CAL DENIED appears, then an internal switch has been set to prevent the
calibration from being changed. (See the Service Manual.)
lf the password is incorrect, an error occurs. If the active password is lost, the
calibration function can be recovered by setting an internal switch that defeats
password protection. (See the Service Manual.)
