ABSTRACT:
A cable testing apparatus and method are disclosed, the apparatus and method being particularly useful as a seismic cable tester to enable rapid cable check-out, and, as a battery operated portable unit, being particularly useful for final check-outs in field operations. The wires of a multi-wire cable are sequentially tested by pairs with sequential testing being interrupted and an indication of the pair of wires then found to be open being displayed each time an open is sensed. The apparatus includes electrical control circuitry for controlling multiplexing of the wire pairs of the cable to be tested and for determining the display to be presented so that the display is indicative of each pair of wires of the cable found to be open.
