Calibration and Troubleshooting

6-2 975-0200-01-01

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

Main Voltage and Current Calibration Principle

Understanding the Problem

Figure 6-1 illustrates two sources of analog programming error: gain error

and offset error. Gain error is the departure from the ideal slope of the

measured versus programmed line. Offset error is the magnitude of the

measured value when the programmed value is zero.

For best results, the next recommended action is gain calibration for 90%

of maximum value and offset calibration for 10% of maximum value.

Perform gain calibration again.

CAUTION

Calibration procedures should only be performed by qualified user.
