ABSTRACT:
An aircraft multi-function wire and low voltage insulation tester, having a time domain reflectometer, a digital multi-meter, and a matrix switch integrated in a computer, and a connector having a plurality of output pins allowing a plurality of wires to be hooked up simultaneously. The matrix switch connects the output pins to either the digital multi-meter or the time domain reflectometer perform the respective tests. Corresponding to the output pins, the matrix switch has a plurality of input/output channels, such that wire paths can be established between the output pins. The time domain reflectometry and characteristic tests can thus be performed on each line of a cable to be tested, and each wire path established between the output pins or the lines.
