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
step 3.
To calibrate the isolated resistive programming of voltage:
1. Disconnect the load and connect the voltmeter to the output.
2. Connect the 4.000 kΩ resistor to the isolated connector. One
terminal to resistive programming of voltage (J3.8), and
voltage programming of voltage (J3.3), and the other to
common (J3.2).
3. Set the resistive APG level to 4 kΩ The SCPI command is:
SYST:COMM:APR:LEV 4
4. Set input source as Resistive Isolated for Voltage
Programming. The SCPI command is:
SYST:REM:SOUR IAR
5. 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.
6. Enter the interactive calibration mode by sending the SCPI
command:
CAL :OUTP:ANAL:RES:ISOL
7. Press on the terminal keys - or + to reduce or increase the
main output voltage value. Adjust the main output voltage to
100%.
8. Press any key than the + or - keys to exit from interactive
calibration mode.
