Calibration 2-5
NOTE With calibration unlocked, the sense function and range track the source function and
range. That is, when :SOUR:FUNC is set to VOLT, the :SENS:FUNC setting will be
'VOLT:DC'. When :SOUR:FUNC is set to CURR, the :SENS:FUNC setting will be
'CURR:DC'. A similar command coupling exists for :SOUR:VOLT:RANG/
:SENS:VOLT:RANG and SOUR:CURR:RANG:SENS:CURR:RANG.

To unlock calibration via remote, send the following command:

For example, the following command uses the default password:
