This tone generator with amplifier probe identifies and traces wires or cables within a group without damaging the insulation. This tool is designed for installing networks and checking items. The tone generator emits a single signal or multiple frequency signals and features two individual test cartridges and a 4-pin test joint. When wires are bound and hidden within walls or embedded in a barrier layer, the tone signal sent from the main unit can be easily tested with the probe. The continuity of a cable, a cable fault, the polarity of the circuit, a network, or the operating voltage of the module cable can be checked with this group tester. The circuit path and the exact position can be assessed using the indicator light and the tone from the speaker.
