Describe Powered by a 2pcs 9V battery, V210 driving and short finder circuit tester can easily locate circuit breaker points, open connections, disconnections, wire damage, current leakage with tone changes, even trace wires/cables, without even damaging the insulation. This is a convenient, efficient circuit tool for DIYER, electricians and technicians that can easily and quickly judge the continuity of cables/wires and diagnose the continuity of circuit breakers. Open the road Turning on the wire will immediately detect and remind you to turn on the circuit. Easily find short circuits, breaks, open connections, current leakage and micro wires. The transmitter and receiver LEDs indicate open or short circuit conditions. This car's short and open finder, car repair tool is designed to identify and track wires or cables without damaging the insulation. You can also use it in checking short circuits and positioning open circuits, etc. Wire tracking Simply connect the transmitter to the circuit or wire being tested (instead of blown fuses, connectors, wires with open wires, a bulb socket, etc.) and use a tracer flexible probe to scan the circuit/wire to find the trouble point. Check the short circuit The Car Short Circuit Finder allows you to identify intermittent circuit problems by bending wires or connectors and listening to changes in the receiver tone. This car circuit finder with 6.7-inch flexible probe can help get to crowded places. How to use The short circuit finder is equipped with an adjustable 7-inch soft , providing flexibility to reach difficult areas. This feature makes this product a must-have for professionals and DIY enthusiasts. The probes of the receiver are made of curly steel and can be bent as needed to access wires in crowded or challenging spaces. Depending on the characteristics and sensitivity settings of the circuit, the probe will detect signals from the wires at various locations. For best results, locate the probe tip (black cover) of the receiver vertically (at 90 degrees) or below the tracked wire. Automotive circuit tracer is various circuits between 6 and 42 volts, including cars, trucks, tractors, boats, boats, RVS, etc. It is a multifunctional function for various applications, and its operating voltage range is large.
