Non-isolated Voltage Programming of Current 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 current: 
1.  Short the main output with a shunt. Connect a multimeter to 
measure the voltage across the shunt. 
2.  Connect the input voltage source to the non-isolated 
connector, current programming (J1.10 - J1.7). 
3.  Set the Voltage APG level to 4 V. The SCPI command is: 
SYST:COMM:APR:LEV:CURR     4 
4.  Set the input source voltage to 4.000 V. 
5.  Set the input source as Voltage Non-Isolated for Current. The 
SCPI command is: 
SYST:REM:SOUR:CURR     AVOL 
6.  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. 
7.  Enter the interactive calibration mode by sending the SCPI 
command: 
CAL:OUT P:ANAL:CURR 
8.  Press the terminal keys - or + to reduce or increase the main 
output current value. Adjust the main output current to 100%. 
9.  Press any key other than the + or - keys to exit from 
interactive calibration mode.
