Connect the of your load to the opposite large bolt on the shunt. Connect Pin 3 of the meter to this side using the corresponding small screw terminal on the shunt.
Connect the of your power source directly to Pin 1 of the meter, and bridge a wire from Pin 1 to Pin 2 (or connect the load's positive wire directly to the source positive). peacefair pzem-051 manual
