Non-isolated Resistive Programming of Voltage Calibration
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.
To calibrate the non-isolated resistive programming of voltage:
1. Disconnect the load and connect the voltmeter to the output.
2.
Connect the 4.000kΩ 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 4kΩ 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.
