Audio generator kit, electrical cable detector, 200EP high-precision cable tracer circuit tester, line-finding inductance amplifier

[High Quality] This tone and probe kit is made of high-quality, wear-resistant, and corrosion-resistant materials. The normal gain is 30 dB, and the input impedance is nominally 100 MΩ. Please note that the wire tracer requires two 9V batteries (not included). [Powerful Function] When used with any sound source, this professional wire probe and toner kit with adjustable volume can identify and trace wires or cables in a group without damaging the insulation. The clamp mode can be used for direct measurement of non-terminal cables, as well as for telephone and network line measurements. [Easy to Use] The method is simple, and the test results are accurate. The insulation probes and built-in speakers effectively prevent short circuits in conductors. The measurement range includes line tracing, short-circuit testing, clearing/busy/ringing identification, and safer operation.
[Safety and High Accuracy] The circuit tester features a spring-loaded ON/OFF button; adjustable volume sensitivity control; a recessed terminal port for mobile phone connection; and a carbon fiber resistive plastic tip to prevent accidental short circuits when detecting wires. It offers an optional continuous or adjustable generator, simple operation, and accurate test results.
[Scope] The 200EP sound source and probe kit are widely used in cable and wire maintenance. The measurement range includes line tracing, short-circuit testing, and clearing/busy/ringing identification. For non-terminal cables, the alligator clip mode can be used for direct measurement of telephone and network cables. Equipped with built-in speakers.
