:LOCK
(:CALibration:PROTected:LOCK)
Purpose To lock out calibration.
Format :cal:prot:lock
Query :cal:prot:lock?
Response 0 Calibration unlocked
1 Calibration locked
Description
Note
The :LOCK command lets you lock out comprehensive calibration after
completing those procedures. Thus, :LOCK performs the opposite of
sending the password with the :CODE command. The :LOCK? query
returns calibration lock status.
To unlock calibration, send the :CODE command with the appropriate
password.
Example :CAL:PROT:LOCK Lock out calibration
:SAVE
(:CALibration:PROTected:SAVE)
Purpose
Format
Description
Note
To save calibration constants in EEROM after the calibration procedure.
:cal:prot:save
The :SAVE command stores internally calculated calibration constants
derived during
comprehensive in EEROM. EEROM 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 only be temporary unless the :SAVE command is sent to
permanently store calibration constants. Calibration data will not be saved if:
(1) calibration was not unlocked by sending the :CODE command, (2)
invalid data exists (for example, cal step failed or was aborted), or (3) an
incomplete number of cal steps were performed (for example, omitting a
n
eg
ative full-scale step).
Example :CAL:PROT:SAVE Save calibration constants
