1. Powerful Circuit Testing with Non Invasive Wire TracingThe V210 Circuit Tester, powered by two 9V batteries, is a efficient tool for locating circuit breakers, open connections, disconnections, wire damage, and current leakage. With tone changes and LED indicators, it allows you to trace wires and cables without damaging insulation—making it ideal for DIYers, electricians, and technicians. 2. Quick Detection of Short Circuits Open CircuitsThis short and open finder immediately alerts you when a live wire is detected. It easily identifies short circuits, breaks, open connections, micro wires, and current leakage. The transmitter and receiver LEDs clearly indicate the status of the circuit, helping you diagnose issues quickly and accurately. 3. Ideal for Automotive Electrical TroubleshootingDesigned specifically for car , this short circuit and open finder helps identify and trace wiring problems without damaging insulation. It's for checking short circuits, locating open circuits, and testing connectors or fuses in automotive electrical systems. 4. Effortless Wire Tracking with Flexible ProbeSimply connect the transmitter to the circuit—whether it's a blown fuse, open wire, bulb socket, or connector—and use the flexible tracer probe to scan and locate faults. This makes pinpointing trouble spots fast and precise, even in tight or complex wiring areas.
