Changing the password through a remote interface
To change the calibration password through a remote interface, first send the present password,
and then send the new password. For example, the following command sequence changes the
password from the ‘KI006482’ remote default to ‘KI_CAL’:
:CAL:PROT:CODE 'KI006482'
:CAL:PROT:CODE 'KI_CAL'
You can use any combination of letters and numbers up to a maximum of eight characters.
NOTE 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.
Resetting the calibration password
If you lose the calibration password, you can unlock calibration by shorting together the CAL pads,
which are located on the display board. Doing so will also reset the password to the factory default
(006482, front-panel; KI006482, remote).
