Non-isolated Voltage Programming of Voltage Calibration 
Important: For maximum accuracy at a specific APG level, follow the 
calibration procedure again but use the intended operating voltage level in steps 
3 and 4. 
To calibrate the non-isolated voltage programming of voltage: 
1.  Disconnect the load and connect the voltmeter to the output. 
2.  Connect the input voltage source to the non-isolated 
connector, voltage programming (J1.9 - J1.7). 
3.  Set the Voltage APG level to 4 V. Send the SCPI command: 
SYST:COMM:APR:LEV     4 
4.  Set input source voltage to 4.000 V. 
5.  Set the input source as Voltage Non-Isolated for Voltage 
Programming. The SCPI command is: 
SYST:REM:SOUR     AVOL 
6.  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. 
7.  Enter the interactive calibration mode by sending the SCPI 
command: 
CAL:OUTP:ANAL 
8.  Press the terminal keys - or + to reduce or increase the main 
output voltage value. Adjust the main output voltage to 100%, 
measured on the external voltmeter on the output. 
9.  Press any key other than the + or - keys to exit from 
interactive calibration mode.
