Calibration Reference

Miscellaneous commands
Miscellaneous commands are those commands that perform such functions as unlocking
calibration, 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 '<password>'
Parameter
Up to an 8-character string including letters and numbers.
Description
The :CODE command sends the password/code and enables calibration
when performing these procedures via remote. The correct password
must be sent to the unit before sending any other calibration command.
The default remote password is KI002500.
Note
• The :CODE command should be sent only once before performing cali-
bration. Do not send :CODE before each calibration step.
• To change the code, first send the present code, then send the new code.
• The password parameter must be enclosed in single quotes.
• If you change the first two characters of the password to something other
than “KI”, you will not be able to unlock calibration from the front panel.
Example
:CAL:PROT:CODE 'KI002500'
Send default code of KI002500.
