1 x Inverter/Motor test unit (single phase)

1 x HF 003 Current Shunt (shunt resistance = 470mΩ)

Wiring Configuration:

Connect BNC safety lead between the “A EXT” BNC on the

rear of the PPA55xx and the BNC connector on the HF shunt

*Remember disconnect all leads to appropriate channels internal current shunt*
