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 step 3.
To calibrate the 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 Isolated connector
(J3.4 -J3.6).
3. Set the Current 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 Isolated for Current. The SCPI
command is:
SYST:REM:SOUR:CURR IAV
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:CURR:ISOL
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 the
interactive calibration mode.
