Abstract
In a conductor cable for seismic exploration, where the cable will have very high resistance transducers connected to it for transmitting signals from one or more transducer stations to a recording station, there is a controllably conductive path connected across the transducers. The path is only conductive at a voltage greater than the maximum of the signals. And, a constant current source is applied at the recording station. Also, a voltmeter is employed to measure the continuity of the cable.
