Offset Calibration
Offset calibration of the power supply provides the best accuracy
in low-range input current.
To perform offset calibration:
1. Set the voltage source attached to the non-isolated current
APG input to 10% of the nominal current level, in this case
0.400 V.
2. Turn the output power on.
3. Read the input voltage value from the voltmeter connected in
step 2 of the gain calibration.
4. Type SCPI input current calibration command with voltage
noted in step 3 as the parameter “data”.
For example, you would type :CAL:INP:ANAL:CURR 0.43.
After performing offset calibration, it is highly recommended that
you repeat gain calibration.
