ABSTRACT:
Apparatus is disclosed for testing a cable by connecting Zener diodes or similar acting structures between terminating contacts at one end of the cable and then selectively connecting a series connected DC voltage source and resistor between terminating contacts at the other end of the cable. The diodes introduce unique voltage drops which determine the current flowing from the voltage source. The magnitude of the current is indicative of the condition of the cable with respect to continuity, correct connections, and interconductor short circuits.
