1. Powerful Circuit Testing with Non-Invasive Wire Tracing The V210 Circuit Tester, powered by two 9V batteries, helps locate circuit breakers, open connections, disconnections, wire damage, and current leakage. With tone signaling and LED indicators, it traces wires and cables without damaging insulation, making it suited for DIYers, electricians, and technicians. 2. Quick Detection of Short Circuits & Open Circuits This short and open finder provides immediate alerts when a live wire is detected and can identify short circuits, breaks, open connections, micro wires, and current leakage. The transmitter and receiver LEDs clearly indicate the circuit status for quick and accurate diagnostics. 3. Ideal for Automotive Electrical Troubleshooting Designed for car repair, this short circuit and open finder helps identify and trace wiring problems without insulation damage. It is ideal for checking short circuits, locating open circuits, and testing connectors or fuses in automotive electrical systems. 4. Effortless Wire Tracking with Flexible Probe 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 enables fast, precise pinpointing even in tight or complex wiring areas.
