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.
