Calibration and Troubleshooting

Non-isolated Analog Programming Calibration
Prior to this, the main output must be calibrated first.
Important: In calibration commands, when + or - keys are expected, any other
key will exit from the calibration mode.
Non-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 non-isolated voltage monitoring:
1. Disconnect the load and connect the voltmeter to the output.
2. Connect the voltmeter to the non-isolated voltage monitoring
output lines (J1.13 - J1.7).
3. Set the Voltage APG level to 4 V. Send the SCPI command:
SYST:COMM:APR:LEV 4
4. Set the input source as Local. Send the SCPI command:
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 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 interactive calibration mode by sending the SCPI
command:
CAL:MON
8. Press on the terminal keys - or + to reduce or increase
monitoring value. Adjust the monitoring value displayed on
the voltmeter that was set up 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.
