Abstract

In order to identify wires whose matching is incorrect and undetectable by a continuity test, the method consists in using two oscillators (O1, O2), one permitting the transmission of high- frequency signals to one wire of the pair, the other transmitting low- frequency signals to a counter permitting the step-by-step exploration of one wire of each pair. Application to wire pairs made up into cables. <IMAGE>
