Isolated Resistive Programming of Current Calibration
To calibrate the isolated resistive programming of current:
1. Short the main output with a shunt. Connect a multimeter to measure the voltage
across the shunt.
2.
Connect the 4.000 kΩ resistor to the isolated connector. One terminal to resistive
programming of current (J3.7), and voltage programming of current (J3.3), and the
other to common (J3.2).
3.
Set the Resistive APG level to 4 kΩ The SCPI command is:
SYST:COMM:APR:LEV:CURR 4
4. Set the input source as Resistive Isolated for Current Programming. The SCPI
command is:
SYST:REM:SOUR:CURR IAR
5. Turn the main output On or send the command:
:OUTP ON
6. Enter the interactive calibration mode by sending the SCPI command:
CAL:OUTP:ANAL:CURR:RES:ISOL
7. Press the terminal keys - or + to reduce or increase the main output current value.
Adjust the main output current to 100%.
8. Press any key other than the + or - keys to exit from the interactive calibration
mode.
