Abstract

A method of conducting a self-test on a non-contact voltage detector with self-test function is disclosed. The method includes receiving at a circuit a signal to power-on the non-contact voltage detector; testing the integrity of a probe by injecting a signal into the probe and checking for receipt of the signal at an input of a circuit; testing the integrity and functioning of the operating LED; testing the integrity and functioning of a voltage indicator LED; and lighting an operating LED only when the probe passes its integrity test and the voltage indicator LED passes its integrity test, otherwise powering down the non-contact voltage detector.
