Output Current

Calibration can also be done via remote control, using SCPI commands. See “Remote Interface Calibration Procedure” on page 187.

Calibration of voltage programming and readback are combined in a single procedure.

1.Set the load to open circuit. Attach a DVM across the output terminals.

2.Enter output voltage calibration menu

Select Output V Cal from the calibration menu. Press ENTER.

You will be prompted to set up for output voltage calibration. Press ENTER when ready.

3.Minimum calibration level

The power supply will automatically set the output voltage to 10%.

4.Enter voltage data

Enter the voltage output, read from the external DVM. Press ENTER

5.Maximum calibration level

The power supply will set the output voltage to 90%.

6.Enter voltage data

Enter the voltage output, read from the external DVM. Press ENTER.

7.Power supply calculates and stores calibration constants.

8.The menu will go to the Output Current Calibration menu.

1.Set the power supply and load operate at full output. You must ensure the power supply is operating in current mode during current calibration. Place a shunt on the load line so that you can measure the current. Attach a DVM across the shunt

2.Enter output current calibration menu

Select Output I Cal from the calibration menu. Press ENTER.

You will be prompted to set up for output current calibration. Press ENTER when ready.

3.Minimum calibration level

The power supply will automatically set the output current to 10%
