3-6
To read calibration lock status.
:cal:prot:swit?
0 Calibration locked
1 Calibration unlocked.
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.
:CAL:PROT:SWIT?
To save calibration constants in EEPROM after the calibration procedure.
:cal:prot:save
None
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).
Calibration will be only temporary unless the :SAVE command is sent to permanently store cal-
ibration constants.
:CAL:PROT:SAVE
Request CAL switch status.
Save calibration constants
