Non-isolated Current Monitoring Calibration
To calibrate the non-isolated current monitoring:
1. Short the main output with a shunt. Connect a multimeter to measure
the voltage across the shunt.
2. Connect the voltmeter to the non-isolated current monitoring output
lines (J1.12 - J1.7).
3. Set the Current APG level to 4 V. Send the SCPI command:
SYST:COMM:APR:LEV:CURR 4
4. Set the input source as Local.
5. The SCPI command is:
SYST:REM:SOUR:CURR LOC
6. Set the main output voltage to 100% by sending the command
SOUR:VOLT <ModelVolt> or use the Rotary knob/Enter button.
7. Turn the main output On by pressing the OUTPUT ON/OFF button
on the front panel or send the command:
:OUTP ON
The OUTPUT ON/OFF button will illuminate.
8. Enter interactive calibration mode by sending SCPI command:
"CAL:MON:CURR"
9. Press on the terminal keys – or + to reduce or increase the 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.
10. Press any key other than the + or – keys to exit from interactive
calibration mode.
Non-isolated Voltage Programming of Voltage Calibration
To calibrate the non-isolated voltage programming of voltage:
1. Disconnect the load and connect the voltmeter to the output.
2. Connect the input voltage source to the non-isolated connector,
voltage programming (J1.9 - J1.7).
3. Set the Voltage APG level to 4 V. Send the SCPI command:
SYST:COMM:APR:LEV 4
4. Set input source voltage to 4.000 V.
