These testers use needle point test prods to indicate continuity

Voltage Range 50-1000 Volts AC. The AC Sensor is a hand held device for determining the presence or absence of 50-1000 volts AC in insulated wires, wall receptacles, fuses, junction boxes, switches, and other voltage carrying electrical systems. The AC...

By applying a tone signal to a wire pair or single conductor, and using an inductive amplifier, permits technicians to identify the conductor within a bundle, at a cross-connect point or remote end.

Features easy method of isolating problems by checking if signals are being generated by computer or terminal equipment. Monitors the most commonly used RS-232 lines.

Identifies faults in 3-wire, 125 VAC circuits.
