Appendix D Analog Input Calibration

The following steps will guide you through the USB-4718 analog input channel software calibration. Please perform BOTH voltage and current input calibrating procedures to complete the calibration of USB-4718’s analog input channels.

D.1 Voltage Input Calibration

You need to calibrate only one channel (AI0). The other channels of USB-4718 will be calibrated automatically.

NOTE: Please make sure that the JP1 on USB-4718 is set to voltage input mode before you start voltage input calibrating.

Step 1: Click the “Setup” button in the Advantech Device Manager win- dow to launch the USB-4718 Device Setting window. Then click “Cali- bration” to start the calibration process. The Calibration Wizard window will pop up.
