Abstract
A method for testing a multicore cable including not less than three insulated wires to identify a correspondence relationship between one end portion and an other end portion of the insulated wires exposed from both ends of the multicore cable. The method includes inputting a test signal, by capacitive coupling, to an end portion of the tested insulated wire among end portions of the insulated wires exposed at one end of the multicore cable, inputting a phase-inverted test signal in an opposite phase to that of the test signal, by capacitive coupling, to an end portion of the insulated wire, other than the end portion of the tested insulated wire, and measuring voltages of output signals output respectively from end portions of the insulated wires exposed at the other end of the multicore cable to identify an other end portion of the tested insulated wire based on the measured voltages.
