Calibration and Troubleshooting

Introduction

The calibration of the power supply is software dependent, and there are no potentiometers to adjust.

Calibration is performed via SCPI commands. The following items need to be calibrated:

•Programmed voltage

•Voltage readback

•Programmed current

•Current readback

•Non-isolated voltage monitoring

•Isolated voltage monitoring

•Non-isolated current monitoring

•Isolated current monitoring

•Isolated source for analog programming

•Non-isolated source for analog programming

•Over voltage protection system

CAUTION: Equipment damage

Calibration procedures should only be performed by qualified user.
