Non-isolated Analog Programming Calibration
Prior to this, the main output must be calibrated first.
Non-isolated Voltage Monitoring Calibration
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 knob/Enter button.
6. Turn the main output On by pressing the OUTPUT ON/OFF button
on the front panel or send the command:
:OUTP ON
The OUPTUT ON/OFF 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.
Important: In calibration commands, when + or – keys are expected, any
other key will exit from the calibration mode.
