Calibration and Troubleshooting

Over Voltage Protection Calibration

Important: The Voltage Calibration must be done before performing this procedure. If this is not done the OVP calibration will be inaccurate.

To calibrate the over voltage protection:

1.Turn on the power supply.

2.Select the VAP mode to be Off.

3.Set the voltage set point to be 90% of the model voltage and the current to be 10% of the model current.

4.Turn on the main power output.

5.Execute the OVP calibration SCPI command:

:CAL:PROT <output value set in step 3>

6.The power supply will enter into self-calibration mode. The output voltage display blinks OVP CAL. After several seconds, the calibration will complete and the display will return to normal operation with output off.

Calibration of the power supply is complete.

Important: The output (main) voltage must be precalibrated.

The SCPI command (s) for these instructions are:

[:]CALibration[:VOLTage]:PROTection[:OVER] {<expected output value>}
