RUIZHI Circuit Tester, 200EP High-Precision Wire & Sound Probe Kit, Battery Powered

• [High Quality] This clay and probe kit is made of high-quality, wear-resistant and corrosion-resistant materials. The normal gain is 30dB, and the input impedance is nominally 100M ohm. Please note that the cable tracer requires two 9V batteries (not included).
• [Powerful Function] [Powerful Function] When used with any sound source, the professional wire and sound probe kit with adjustable volume can identify and track the wires or cables in a group without damaging the insulation. The pliers mode can be used for direct measurement of non-terminal cables as well as for telephone and power line measurements.
• [Easy to use] The method is simple and the test results are accurate. With insulation probes and built-in speakers, cable short circuits can be effectively avoided. The measurement spectrum includes line tracking, short circuit testing, /busy/bell detection and safer use.
• Safety and high precision: The circuit tester has a spring-loaded on/off button, an adjustable volume control, a recessed connection socket for mobile phones and a durable carbon fibre tip that prevents accidental short circuit when detecting wires. Optional continuous or adjustable generator, simple method and accurate test results.
• [Scope of application] 200EP sound generator and probe set with probe are often used for the maintece of cables and lines. The measuring range includes line tracking, short circuit test and /busy/bell detection. For cables that are not terminals, crocodile clip mode can be used for direct measurements, and it can also be used for measuring telephone lines and network cables. The optional continuous or pitch-changing generator is equipped with a built-in speaker on the probe
