Non-isolated Resistive Programming of Voltage Calibration
To calibrate the non-isolated resistive programming of voltage:
1. Disconnect the load and connect the voltmeter to the output.
2. Connect the 4.000k
Ω resistor to the non-isolated connector, resistive
programming of voltage, and voltage programming (J1.9-J1-11, and
J1.7).
3. Set the resistive APG level to 4k
Ω. The SCPI command is:
SYST:COMM:APR:LEV 4
4. Set the input source as Resistive Non-Isolated for Voltage
Programming. The SCPI command is:
SYST:REM:SOUR ARES
5. 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.
6. Enter the interactive calibration mode by sending the SCPI command:
CAL:OUTP:ANAL:RES
7. Press the terminal keys – or + to reduce or increase main output
voltage value. Adjust the main output voltage to 100%.
8. 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 resistance level in
steps 2 and 3.
