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 k
Ω
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 k
Ω
. 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.
