: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 The

:LOCK command allows you to lock out calibration after completing

those procedures. Thus,

:LOCK performs the opposite of sending the code

with the

:CODE command. The :LOCK? query returns calibration lock sta-

tus.

NOTE To unlock calibration, send the

:CODE command with the appropriate password.

Purpose To unlock calibration so that you can perform the calibration procedures.

Example

:CAL:PROT:LOCK Lock out calibration

:SAVE

(:CALibration:PROTected:SAVE)

Purpose To save calibration constants in EEROM after the calibration procedure.

Format

:cal:prot:save

Description The :SAVE command stores internally calculated calibration constants

derived during calibration 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).

NOTE Calibration will be only temporary unless the

:SAVE command is sent to permanently

store calibration constants. Calibration data will not be saved if any errors occurred.

Example

:CAL:PROT:SAVE Save calibration constants
