External current shunts can be used as an alternative to the instruments internal
shunt as a fixed value Impedance circuit. Note do not use both shunts together
Test equipment for demonstration:
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*
Set up PPA to read the external current shunt:
Press “RANGE” button
Connect Yellow
4mm lead from
source
Connect Black
4mm lead from
Load
Shunt Resistance = 470mΩ
Continuous Current = 3A rms
