The single biggest reason to buy is its combination of live AC\/DC\/resistance readings and an integrated, resettable circuit breaker that lets a user trace shorts and actively power components without fumbling jumper wires. It cuts diagnostic time by showing polarity, voltage drop and min\/max signal behavior on a clear backlit LCD while the long cables make in-vehicle testing far more convenient.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual power and long reach:\u003c\/strong\u003e The kit includes a 20 ft main cable plus a 20 ft extension and a cigarette lighter power option so you can test around longer vehicles and trailers without opening the hood.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFour advanced modes:\u003c\/strong\u003e Active DC voltage, AC signal with max\/min and duty cycle, resistance continuity, and a tone on\/off mode give immediate, task-specific results for most electrical troubleshooting.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComponent activation:\u003c\/strong\u003e The PS100 can apply power or ground to components to check lights, motors, relays and fans without separate jumper leads, speeding diagnosis and reducing errors.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShort tracing with protection:\u003c\/strong\u003e A built-in 10 A resettable circuit breaker trips and sounds a buzzer on overload, helping find shorts while protecting the vehicle and tool.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePolarity and voltage drop detection:\u003c\/strong\u003e Red\/green LED polarity indicators plus an LCD with 0.1 V resolution make it easy to spot bad grounds and voltage drops.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacklit LCD and work lights:\u003c\/strong\u003e A clear digital display and dual head lights support testing in low-light conditions while showing readable numerical values.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThe Autel PowerScan PS100 is ideal for professional auto electricians, mobile technicians and serious DIYers who need faster, more informative troubleshooting than a simple test light or basic multimeter can provide.
