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

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.

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.)
