1) For a single phase meter, what type of shunt resistor should i use (regular two lead resistor, 4 lead or kelvin configuration) in order to sense current? Can you provide the part used with the evaluation kit?

2) Is it necessary to create a voltage divider between neutral and phase wires to satisfy the 500mV input voltage in V1P? or if i follow the test circuit stated in the datasheet with those three resistor in series is enough?

3) Are the diodes(TS4148) needed for normal operation of the circuit, or those are for testing only?

 

Thank you for your time.

 

 

Best Regards,

Nuno
