Isolated Resistive Programming of Voltage Calibration
To calibrate the isolated resistive programming of voltage:
1. Disconnect the load and connect the voltmeter to the output.
2. Connect the 4.000 k
Ω
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 k
Ω
. 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.
Important:
For maximum accuracy at a specific APG level. Follow the
calibration procedure again but use the intended operating resistance level in step 3.
