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.
5. Set the input source as Voltage Non-Isolated for Voltage
Programming. The SCPI command is:
SYST:REM:SOUR AVOL
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:OUTP:ANAL
8. Press the terminal keys – or + to reduce or increase the main output
voltage value. Adjust the main output voltage to 100%, measured on
the external voltmeter on the output.
9. Press any key other than the + or – keys to exit from interactive
calibration mode.
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 4.
