Tone Generator Kit,wire Tracer Circuit Tester,200ep High Accuracy Cable Toner Detector Finder Teste [High Quality]This tone generator and probe kit is made of high-quality materials, wear-resistant, corrosion-resistant. The gain is normal 30dB, the input impedance is nominal 100M Ohm. Note: the wire tracker needs two 9V batteries(NOT INCLUDED).[Accurate & Easy]With optional continuous or adjustable generator, the is simple and the test results are accurate.One button operation. and trace, 1 second to identify cables. Convenient to carry and storage the tester with carrying bag, and protect it from demage, makes it durable.[Powerful & ] When used in conjunction with any tone generator, wire toner probe kit with adjustable volume is designed to identify and trace wires or cables within a group without damaging the insulation. For non-terminal cables, clamp mode can be used for direct measurement, as well as for telephone and network line measurement.[Safety in Use]Circuit tester has spring-loaded ON/OFF button; adjustable volume sensitivity control; recessed terminal ports for handset connection; resistive plastic carbon-fiber tip prevents accidental shorts when probing wires. Insulation probe and built-in loudspeaker can effectively avoid short circuits of conductor and make it safer to use.[Widely Application]This wire tracker are widely used in the maintenance of cables and wires. The measurement area includes line tracking, short circuit test, clear/busy/ringing identification.
