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:OUTP: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.
