The invention discloses a wire connection/disconnection success rate test method of an electric-energy meter automatic-verification system. The method includes: acquiring collection signals of voltage, current, pulse and assistance terminals of the automatic-verification system through a signal sensing module, converting the collection signals into conditioning signals which a signal conditioningmodule can directly collect, and outputting the conditioning signals to the signal conditioning module; carrying out analog-to-digital conversion on the conditioning signals by the signal conditioningmodule to generate digital signals, discretizing the digital signals, and inputting the discretized digital signals to a processor module; and receiving the digital signals through the processor module, and measuring a wire disconnection success rate of the automatic-verification system according to the digital signals.
