2. Send the command to prepare for step 7:
:CALibration:PROTected:STEP7
3. Send the measured result from the digital multimeter (DMM) and shunt value by sending the
command:
:CALibration:PROTected:STEP7:DATA <voltage>, <resistance>
4. Send the following command to query the operation status:
*OPC?
After all of the operations are completed, the instrument returns 1.
