Keithley 6517 - SAVE (:Calibration:protected:save); Switch? (:Calibration:protected:switch?)

Calibration Command Reference
3-6
3.3.3 :SWITch?
(:CALibration:PROTected:SWITch?)
Purpose
To read calibration lock status.
Format
:cal:prot:swit?
Response
0 Calibration locked
1 Calibration unlocked.
Description
The :SWITch? query requests status from the Model 6517A on calibration locked/unlocked
state. Calibration must be unlocked by pressing in on the CAL switch while power is turned on
before calibration can be performed.
Example :CAL:PROT:SWIT? Request CAL switch status.
3.3.4 :SAVE (:CALibration:PROTected:SAVE)
Purpose
To save calibration constants in EEPROM after the calibration procedure.
Format
:cal:prot:save
Parameter
None
Description
The :SAVE command stores internally calculated calibration constants derived during compre-
hensive calibration in EEPROM. EEPROM is non-volatile memory, and calibration constants
will be retained indefinitely once saved. Generally, :SAVE is sent after all other calibration steps
(except for :LOCK).
Programming Note
Calibration will be only temporary unless the :SAVE command is sent to permanently store cal-
ibration constants.
Example
:CAL:PROT:SAVE Save calibration constants
