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.
