Non-isolated Resistive Programming of Current Calibration
Important: For maximum accuracy at a specific APG level, follow the
calibration procedure again but use the intended operating resistance level in
steps 2 and 3.
To calibrate the non-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 non-isolated connector
(APG -J1), one terminal to resistive programming of current
(J1 .12) and voltage programming of current (J1.10), and the
other terminal to the common (J1.7).
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 Non-Isolated for Current
Programming. The SCPI command is:
SYST:REM:SOUR:CURR ARES
5. 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.
6. Enter the interactive calibration mode by sending the SCPI
command:
CAL:OUTP:ANAL :CURR:RES
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
interactive calibration mode.
