Two wiring methods:
(1) Two-wire wiring method: this method is relatively simple and convenient.Note: It must be connected to the 2 terminals [A+] and [A-].
(2) The four-wire wiring method: the voltage measurement is not affected by the voltage drop of the wire, so that the voltage measurement.The quantity is more accurate, and it is recommended that buyers with a certain circuit basis use this method!
