The following procedure calibrates offset for the V-Local, I-Local and V-Remote.
1. Ensure that no load is connected to the output.
2. Issue clear and reset commands:
*CLS
*RST<n>
3. Set the voltage range of the power supply to low
SOUR<n>:VOLT:RANGE 0
4. Perform the voltage ADC offset calibration
CAL<n>:MEAS:OFFSET:CALC
5. Send the system error query command to make sure calibration was successful.
SYST:ERR?
6. If there is no error returned at the system error query command then save the
calibration result with the following commands
CAL<n>:UNLOCK “6867”
CAL<n>:STORE
CAL<n>:LOCK
7. Optional Commands:
To query the offset of signal V-Local: CAL<n>:MEAS:VLOCAL:OFFSET ?
To query the offset of signal I-Local: CAL<n>:MEAS:ILOCAL:OFFSET ?
To query the offset of signal V-Remote : CAL<n>:MEAS:VREMOTE:OFFSET ?
