After performing offset calibration, it is recommended that you repeat
gain calibration.
Important: For best results, both calibrations may be repeated several times.
The SCPI Command (s) for these instructions are:
[:]CALibration[<channel>]:OUTPut{:VOLTage]{<voltmeter
reading in volts>}
Calibrating the Output Current
Gain Calibration
To perform gain calibration:
1. Disconnect the power supply from the load.
2. Connect the output terminals to a load representing a short
circuit using a precision ammeter.
3. Turn both the power supply and the load On.
4. Set the voltage set point to maximum. Set the supply output to
90% of the nominal current level.
5. Turn on the output power.
6. The power supply starts up in Constant Current mode.
7. Read the current value on the ammeter display.
8. Type SCPI command with current value as parameter “data”.
For example, type : CAL: OUTP 5.07 if you had an XG 150-5.6
calibrating with the current set point set to 5.04 A and the ammeter
was reading 5.07 amps.
