Miscellaneous commands
Miscellaneous commands are those commands that perform such functions as saving
calibration constants, locking out calibration, and programming date parameters.
:CODE
(:CALibration:PROTected:CODE)
Purpose To unlock calibration so that you can perform the calibration procedures.
Format
:cal:prot:code '<code>'
Parameter Up to a 8-character string including letters and numbers.
Description The
:CODE
command sends the code and enables calibration when
performing these procedures via remote. The correct code must be sent to the
unit before sending any other calibration command. The default remote code
is KI002182.
NOTES The
:CODE
command should be sent only once before performing calibration. Do not
send
:CODE
before each calibration step.
To change the code, first send the present code, then send the new code.
The code parameter must be enclosed in single quotes.
If you change the first two characters of the code to something other than "KI", you
will not be able to unlock calibration from the front panel.
Example
:CAL:PROT:CODE 'KI002182'
Send default code of KI002182.
