CONTINUITY TESTING APPARATUS UTILIZING A PLURALITY OF PAIRED RESISTORS

摘要

An apparatus tests for wiring errors in connections between a plurality of pairs of terminals. The apparatus includes a plurality of pairs of matched resistors with one pair of terminals connected between each respective pair of resistors across a voltage source. The voltage across one of each pair of resistors is sensed to determine a voltage above or below a predetermined range of voltages to indicate a defectively wired circuit. Each pair of resistors has matched resistors with values differing sufficiently from every other pair of resistors to operate the voltage sensing facilities in the event there are crossed or erroneous connections.
