- 🥇【FOUR WORKING MODE---INTUITIVE&EASY】Four working modes make circuit detection more simple:DC Voltage, AC Voltage, Resistance, Tone On/ Off. DC Voltage mode can read DC voltage with 0.1V resolution; AC Voltage can read Max & Min voltage, frequency and duty cycle quickly; Resistance mode can read resistance between tip and auxiliary ground wire. Unique Tone On/Off Design is really useful when working in bright areas, it can judge the circuit voltage according to the volume of the sound.
- 🥇【COMPONENT ACTIVATION】The component activation feature is specially designed to troubleshoot on/off-board electrical equipment. 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 POLARITY】Autel Automotive Circuit Tester instantly checks component continuity and quick identifies positive, negative and open circuits.

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 TEST】Autel Electrical System Tester can test the state of sensors, quickly and accurately judge the connectivity of circuit via transmitted signal, performing continuity test. Two ways to test continuity: ✅1: In resistance mode, if the resistance is 0.0Ω and the LED lights up, it means continuity. ✅2: Power up the connection using the power switch, if the circuit brea-ker tr-ips, that means the resistance is low and there is continuity.
