3. Set the current APG level to 4 V. The SCPI command is:
SYST:COMM:APR:LEV:CURR 4
4. Set the input source to local for voltage analog programming. the
SCPI command is:
SYST:REM:SOUR:CURR:ISOL 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 to 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.
7. Enter the interactive calibration mode by sending the SCPI command:
CAL:MON:CURR:ISOL
8. Press 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.
9. Press any key other than the + or – keys to exit from interactive
calibration mode.
Isolated Voltage Programming of Voltage Calibration
To calibrate the isolated voltage programming of voltage:
1. Disconnect the load and connect the voltmeter to the output.
2. Connect the input voltage source to the Isolated connector (J3.3 and
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 voltage to 4.000 V.
5. Set the input source as Voltage Isolated for Voltage. The SCPI
command is:
SYST:REM:SOUR:ISOL AVOL
6. Turn the main output to On by pressing the OUTPUT ON/OFF button
on the front panel or send the command:
:OUTP ON
