Salisbury’s self-testing voltage detector kit allow testing to be continuous and automatic. An intermittent flash and beep confiRMS the detector is functioning properly. Self-testing voltage detectors are used to verify live or de-energized conductors. These detectors may be used with insulating rubber gloves or hotsticks using the splined universal end fitting. Testers indicate voltage with an extra bright LED light and a distinctive audible signal. It is recommended that the tester be moved closer to the conductor until a warning is indicated, or it touches the conductor, apparatus or test point.
