2025 All-in-One Power Circuit Tester Kit - Accurate and Reliable: Autel's most accurate circuit tester, equipped with a 160x128 TFT display, is designed for 6-30V vehicle electrical systems. It supports ✅ voltage and polarity testing ✅ continuity checking ✅ signal circuit diagnosis ✅ component activation ✅ bad ground detection ✅ short circuit location ✅ circuit breaker protection. Includes a 20-foot (approximately 6-meter) cable, an additional 20-foot extension cord, and a cigarette lighter plug. The intuitive design makes it ideal for both beginners and professionals.
Advanced Four Operating Modes - Intuitive and Easy to Use: Four versatile modes simplify your circuit testing: DC voltage, AC voltage, resistance, and tone on/off. Accurately read DC voltage with 0.1V resolution, analyze AC voltage min/max values, duty cycle, and frequency, and easily measure resistance between probes. The unique tone on/off mode allows for quick voltage identification even in dimly lit environments, simplifying troubleshooting with this barcode reader scanning tool.
🌎[Component Activation and Testing] Designed for technicians and car enthusiasts, this Autel automotive power circuit probe accurately activates and tests on- and off-board electrical components. Diagnose and confirm the functionality of important systems like blower motors, power windows, wipers, defrosters, lights, radiator fans, and fuel injectors. Whether handheld, onboard, or grounded, this scan tool accurately tests a variety of components.
👍[Instant Polarity Identification] Easily identify polarity and check circuit continuity with the Autel automotive circuit tester. A red LED beeps to indicate a positive connection, while a green LED emits a low tone to indicate a negative connection. Open circuits are instantly identified when both LEDs are off. Built-in LED indicators provide clear, real-time feedback, making diagnostics smoother and more efficient.
💯[Continuity Test, Signal Circuit Test] The Autel electrical system probe tester allows you to quickly and accurately test sensor circuits and diagnose connection issues. It offers two simple continuity check methods: ✅ Resistance Mode: If the resistance reading is 0.0Ω and the LED lights up, continuity is confirmed. ✅ Power Mode: After power is applied, if the circuit breaker trips, it indicates low resistance and continuity is confirmed. Ideal for diagnosing circuit integrity.
🔧 [Tracing and Locating Short Circuits and Overload Protection] This Autel electrical system tester features a highly sensitive probe for quick and accurate detection. This power circuit probe tester can troubleshoot automotive wiring problems, accurately locating the faulty circuit and its point of failure, saving significant time. It also features built-in short-circuit protection. If overloaded, its internal circuit breaker will trip, ensuring user safety and extending the life of the tester.
