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.
