1 Used to detect and alert you immediately where a circuit is open. You can quickly and easily locate short circuits,open connections,broken wires,current leaks and even trace wires. 2 7in flexible probe can be bent as needed to facilitate reaching wires in ongested or difficult places. According to the characteristics of the circuit and the sensitivity setting, the probe will pick up the signal from the wire within a certain range. 3 In order to obtain the best range, the probe tip (black cap) of the receiver should be perpendicular (at 90 )to the wire being traced and either above or below it. 4 Suitable for use in the new generation of vehicles with mixed or single 42 Volt systems, and can operate at a DC voltage of 6 to 42 volts. 5 With internal protection, protect it from power surges and overloads. Transmitter and receiver LEDs display open circuit or short circuit status. 6 Adjustable sensitivity, suitable for all tracking situations. No wire piercing required, non-contact technology, easy to use.
