Abstract
Abstract Proposed is a continuity tester for a plurality of electric conductors. For this purpose, a signal transmitter for admitting different individual identification signals to such conductors is connected to one of the ends of the conductors, whereby an identification is allocated to each signal transmitter connection. A signal receiver (10) for decoding the different identification signals by means of a decoding device (15) for indicating the allocated identification on a display (16) is connected to the other ends of the conductors. The signal receiver (10) has a sequence switchgear (30) supplying the connected conductors individually and successively with a reference potential in a repeated cycle, whereby the decoding device (15) for decoding the identification signals is formed at least on the one other conductor in each case. The signal transmitter has a signal generator generating for each of the signal transmitter connections the allocated identification signals multiple times, in a way such that no signal overlappings occur overall. A separate reference line can be completely omitted in this way, and the connected conductors to be tested can be simultaneously checked by means of the signal receiver (10), i.e., the respective identifications of said conductors are simultaneously indicated on the display (16).
