The following procedure calibrates offset of the current ADC for the voltage range
high.

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 high

SOUR<n>:VOLT:RANGE 1

4. Perform the voltage ADC offset calibration

CAL<n>:MEAS:IADC: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 command

CAL<n>:UNLOCK “6867”
CAL<n>:STORE
CAL<n>:LOCK

7. Optional Commands

To query the voltage ADC offset:

CAL<n>: MEAS:IADC:OFFSET ?

8. Reset the unit

*RST<n>
