200EP tone generator wire tracer with probe are widely used in the maintenance of cables and wires. The measurement area includes line tracking, short circuit test, clear/busy/ringing identification. Insulation probe and built-in loudspeaker can effectively avoid short circuits of conductor and make toner and probe kit to use, essential tool for electricians The tone generator and probe kit is made of high-quality materials, wear-, , small in overall weight, and easy to carry. The gain is normal 30dB, input impedance is nominal 100M Ohm, 200EP inductive amplifier. Note:The wire tracker needs two 9V batteries(NOT INCLUDED) When used with any tone generator, the professional wire toner probe kit has adjustable volume for identifying and tracking wires or cables within a group without insulation! For non-terminated cables, the clamping can be used for direct measurements as well as for telephone and network line measurements Electric circuit tracer has spring-loaded ON/OFF button, easy and convenient to operate; Same group cable tracking is recognized in only 1 second; With optional continuous or adjustable generator, the is simple and the test results are accurate., Weight: 0.661386786 Pounds, Manufacturer: Junterone
