B-6 Calibration Reference Model 2750 Multimeter/Switch System Service Manual
:LOCK?
(:CALibration:PROTected:LOCK?)
Purpose To read comprehensive calibration lock status.
Format :cal:prot:lock?
Response 0 Comprehensive calibration locked.
1 Comprehensive calibration unlocked.
Description The :LOCK? query requests status from the Model 2750 on calibration
locked/unlocked state. Calibration must be enabled sending the :CODE
command before calibration can be performed.
Example :CAL:PROT:LOCK? Request cal lock state.
:SAVE
(:CALibration:PROTected:SAVE)
Purpose To save calibration constants in EEROM after the calibration procedure.
Format :cal:prot:save
Parameters None
Description The :SAVE command stores internally calculated calibration constants
derived during both comprehensive and manufacturing calibration in
EEROM. (EEROM is non-volatile memory.) Calibration constants will
be retained indefinitely once saved. Generally, :SAVE is sent after all
other calibration steps (except for :LOCK).
NOTE Calibration will be only temporary unless the
:SAVE
command is sent to per-
manently store calibration constants.
Example :CAL:PROT:SAVE Save calibration constants.
