D.2 Current 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 current input
mode before you start voltage input calibrating.

Step 1: Please follow the procedures of voltage input calibration but
select the current input range setting in Calibration Wizard.

current source) and the full range calibration (connect to a 20mA cur-
rent source) as well.
