2025 ALLINONE POWER CIRCUIT TESTER KITACCURATELYAutel Circuit Tester is most accurate power circuit probe tester yet, with 160x128 TFT display test all 630 volt vehicle electrical systems. It supports VoltagePolarity TestContinuity TestSignal Circuit TestComponents ActivateCheck Bad GroundingLocate Short CircuitsShortcircuit ProtectedCircuit Breaker Protection, etc. Besides, Autel Power Circuit Tester has extra long Cables itself with 20ft, and extra with 20ft cable, also comes with a cigarett.e lighter plug. Intuitive interface with ergonomic design makes it be best gif.t for all novice drivers or pro circuit repairers. ADVANCED FOUR WORKING MODEINTUITIVEEASYFour working modes make circuit detection more simple. DC Voltage, AC Voltage, Resistance, Tone On Off. 1 DC Voltage mode can read DC voltage with 0.1V resolution. 2 AC Voltage can get Min Max voltage, duty cycle and frequency quickly. 3 Resistance mode to read resistance between tip and auxiliary ground wire. 4 Unique Tone On Off Design is really useful when working in dim areas, it can judge the circuit voltage according to the volume of the sound. COMPONENT ACTIVATION TESTThis Autel automotive power circuit probe tester can activate components onoffboard electrical system equipment, is designed for car technician or car enthusiasts. By activating the signal generated by the component, you can accurately judged whether the component is intact, such as blower motor, power window motor, windshield wiper, rear window defroster, lights, radiator fans, fuel injectors, etc. Autel circuit tester automotive tool can activate component in your hand in the vehicle with ground etc. INSTANT IDENTIFY POLARITYAutel Car Circuit Tester instantly checks component continuity and quick identifies positive, negative and open circuits. When the positive terminal is connected, red LED lights up with beep sounds. When the negative terminal is connected, green LED light up with a low tone. If an open circuit, neither of LED light will not light. The indicator light is a considerate working guide to facilitate the smooth operation of detection. CONTINUITY TEST, SIGNAL CIRCUIT TESTAutel Electrical System Probe Tester can test the state of sensors, quickly and accurately judge the connectivity of circuit via transmit signal, performing continuity test. Two ways to test continuity 1 In resistance mode, if the resistance is 0.0 and the LED lights up, it means continuity. 2 Power up the connection using the power switch, if the circuit breaker trips, that means the resistance is low and there is continuity. TRAC.KING LOCATING SHORT CIRCUITS, OVERLOAD PROTECTIONThis Autel Electrical System Tester utilizes highly sensitive probes to provide fast and accurate detection. 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 builtin 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. 20FT EXTENSION CABLE, BUILTIN FLASHLIGHTAutel automotive electrical tester comes with extra 20ft extension cable in addition to its own 20ft cable, allowing you to access any position of the vehicle and test it. Ideal for trailer wiring, it can be tested along the vehicle without having to find a suitable ground point. The builtin flashlight is convenient for detection, even in the dark or dim environment, it can provide the best view for who need to work in night.
