Calibration and Troubleshooting

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

6

 

calibration mode.
