The PXI-4022 amplifies a current and converts it into a voltage that varies linearly from 0 to ±10V based on a selectable current range. The voltage is read using a DMM and then converted back into Amps using LabVIEW. The conversion is dependent on the current range that is selected when configuring the PXI-4022.
