Autel PowerScan PS100 Circuit Probe Tester Kit for 6-30V Vehicles, 20ft Extendable Cable, Built-in Flashlight, Electrical Diagnostic Tool

??【ADVANCED FOUR WORKING MODES—INTUITIVE & EASY】Streamline your circuit testing with four versatile modes: DC Voltage, AC Voltage, Resistance, and Tone On/Off. Accurately read DC voltage with 0.1V resolution, analyze AC voltage with Min/Max values, duty cycle, and frequency, and measure resistance between probes effortlessly. ??【COMPONENT ACTIVATION & TEST】Designed for technicians and car enthusiasts, this Autel circuit probe tests and activates electrical components on/off-board. Quickly diagnose systems like blower motors, power windows, wipers, lights, fans, and fuel injectors. Works precisely in-hand, in-vehicle, or grounded. ??【INSTANT IDENTIFY POLARITY】Effortlessly identify polarity and check circuit continuity with the Autel Car Circuit Tester. A red LED with a beep indicates a positive connection, while a green LED with a low tone signals a negative connection. Open circuits are instantly recognizable as neither LED lights up. The built-in LED indicator provides clear, real-time feedback, making your diagnostics smooth and efficient. ??【CONTINUITY TEST, SIGNAL CIRCUIT TEST】 It offers two easy ways to check continuity: ✅ Resistance Mode: If the resistance reads 0.0Ω and the LED lights up, continuity is confirmed. ✅ Power Mode: When powered up, if the circuit breaker trips, it indicates low resistance and confirms continuity. Perfect for diagnosing circuit integrity. ??【TRAC.KING & LOCATING SHORT CIRCUITS, OVERLOAD PROTECTION】This power circuit probe tester can troubleshoot the car wiring circuit, accurately find the faulty wires and their fault points, saving a lot of time. It has a built-in short circuit protection. If overloaded, its internal circuit breaker will trip to ensure the safety of users and prolong the service life of the tester.
