Abstract
An automatic cable assembly testing apparatus and procedure. The connectors at each end of a cable assembly are isolated from the cable and from a test source. Each connector is then injected with a plurality of test frequencies and the leakage currents sensed for each of these tests. The leakage current for a particular test is compared against a corresponding reference level and pass/fail lamps are used to provide a visual indication of the test results. The sequence of tests for each end of a cable assembly over a range of frequencies can either be accomplished either automatically or manually. The preferred embodiment illustrates a microprocessor based controller for operating the system.
