The following procedure calibrates offset of the current ADC for the voltage range
low.
1. Ensure that no load is connected to the output.
2. Issue clear and reset commands:
*CLS
*RST
3. Set the voltage range of the power supply to low
SOUR:VOLT:RANGE 0
4. Perform the voltage ADC offset calibration
CAL: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 commands
CAL:UNLOCK “6867”
CAL:STORE
CAL:LOCK
7. Optional Commands:
To query the current ADC offset: CAL: MEAS:IADC:OFFSET ?
8. Reset the unit
*RST
