Intuitive interface with ergonomic design makes it be best gif.t for all novice drivers or pro circuit repairers.
- ADVANCED FOUR WORKING MODE---INTUITIVE&EASYFour 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. Note: Any issues please reach out to us via: autelsupply@ outlook. com.
- COMPONENT ACTIVATION & TESTThis Autel automotive power circuit probe tester can activate components on/off-board 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. If device is not working properly, please cont.act:autelsupply@ outlook. com get support.
- 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 brea-ker tr-ips, 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 built-in short circuit protection.

Best bang for buck when it comes to electrical probing. Back in the day I was using Power Probe's equipment and yes it gets the job done but with this Autel one it changes the game. With all the functions and features that this probe brings it's needless to say that electrical diagnosis will get easier; of course if you know what you're doing. In the department of design it feels familiar as the one from Power Probe since the design of the body is quite similar. When it comes to build quality I can certainly say that it's sturdy and feels high quality in the hands. When used it greets you with different options to measure voltage, ohms, continuity and other electrical diagnosis. Something that threw me off from this was the cycle duty which I genuinely did not expect it to have so I don't really have to use a multi-meter. Needless to say, whether you're a mechanic, electrician or something along those trades this tool is definitely an amazing buy!

I compared this to a power probe and this product does the same and more. The extra cable makes it easier to work with cars as well as trucks or trailers. Easy to use, connectivity and portability are good. I have own this Autel power scan for a few months and i can say is durable and it performs excellent.

For those who are new to power probes. Do not just start applying power to circuits without disconnecting connectors and isolating the circuit or device First. If you just apply power to the harness with out isolating what you are testing you could quickly back feed the wires and damage other components like modules or ECM's. Always isolate circuit before testing. If you don't you are providing techs like myself with job security when frie electronics. This is my second power probe from Autel same brand same model! It is super good quality lead and lots of length which is super nice working on dump trucks with long trailers!! The display and multi function is great and saves many trips back to the tools box to get a meter!! I wish the circuit breaker was service friendly as My previous probe that's what decided to fail and I have not been able to find a replacement breaker yet... I may just solder in some wire leads and a fuse block and keep it around as a spare.

I’ve been using this for the past few years on a daily basis. If you get a back probe set with it, you’ll barely bust out the multimeter. Just make sure if you’re shooting power anywhere that you’re not going to fry the circuit by back feeding it. Also, I’ve found that using AC mode on automotive sensors that pulse (crank sensor etc.) you can get a solid reading almost like a cheap oscilloscope.
