Calibration and Troubleshooting

Calibration Procedure for Isolated Modes

The main output and the non-isolated mode must be calibrated first.

Isolated Voltage Monitoring Calibration

Important: For maximum accuracy at a specific APG level. Follow the calibration procedure again but use the intended operating voltage level in steps 3 and 8.

To calibrate the isolated voltage monitoring:

1.Disconnect the load and connect the voltmeter to the output.

2.Connect the voltmeter to the isolated voltage monitoring output lines (J3.5 - J3.6).

3.Set the Voltage APG level to 4 V. The SCPI command is:

SYST:COMM:APR:LEV 4

4.Set the input source to local for voltage analog programming. The SCPI command is:

SYST:REM:SOUR LOC

5.Set the main output voltage to 100% by sending the command:

SOUR:VOLT <ModelVolt>

or use the rotary adjust/Enter control.

6.Turn the main output to On by pressing the OUTPUT ENABLE Main button on the front panel or send the command:

:OUTP ON

The OUTPUT ENABLE Main button will illuminate.

7. Enter the interactive calibration mode by sending the SCPI command:

CAL:MON:ISOL

8.Press the terminal keys – or + to reduce or increase the monitoring value. Adjust the monitoring value displayed on the voltmeter that was setup in Step 1 to read as close as possible to 4.000 V.

9.Press any key other than the + or – keys to exit from interactive calibration mode.
