3.1 Measurement With Shunt

This connection method allows the user to install a shunt resistor on the EVM and connect the common-mode voltage and load to incorporate the test device directly into a sample application, as Figure 3-1 shows. To configure a measurement evaluation with a shunt, follow these procedures.

  1. Install a shunt resistor into the Rx03 (x=1, 2 or 3) location.
  2. Connect the common-mode voltage to the VinP terminal using either the surface mount or through hole test point. Solder test leads on to the test points when necessary for reliable connection.
  3. Connect load to the VinNterminal.
