Chapter 3 Calibration Procedures

General Calibration/Adjustment Procedure

General Calibration/Adjustment Procedure

The calibration procedures from the front panel are described in this section. For output voltage calibration, disconnect all loads from the power supply and connect a DVM across the output terminals to be calibrated. For output current calibration, disconnect all loads from the power supply, connect an appropriate current monitoring resistor across the output terminals to be calibrated, and connect a DVM across the terminals of the monitoring resistor.

The following table shows calibration parameters and points which should be used to calibrate the output voltage and current for each of the three outputs.
