ABSTRACT:
A self-compensating fault locator (10) broadly comprises a testing unit (16) to take measurements across two test points (18), a processing unit (20) to locate faults by analyzing the measurements, and a switching unit (22) that can connect termination points (14) of an electrical circuit (12) to the test points (18) in a sequence controlled by the processing unit (20). The fault locator (10) may also include a harness (24) to connect the electrical circuit (12) to the switching unit (22). The processing unit (20) is preferably programed with the electrical circuit's (12) interconnection information. The processing unit (20) also preferably stores internal characteristics of the fault locator (10). Using the interconnection information and the internal characteristics, the processing unit (20) may accurately locate faults within the electrical circuit (12). Additionally, the processing unit (20) may locate faults within the fault locator (10) and/or the harness (24).
