Autel PowerScan PS100 Circuit Tester: Instantly Identify Circuit Polarity and Test Components with 20-Foot Cable

The Autel PowerScan PS100 is a versatile electrical circuit diagnostic tool that allows you to determine at a glance whether a circuit is positive, negative, or open without reconnecting the clip from one battery pole to the other. With its built-in auxiliary ground wire, you can test continuity immediately. The tool also enables voltage drop tests to check for poor grounding quickly, and the internal circuit breaker protection trips if overloaded, safeguarding the device. The 20-foot (expandable) cable provides excellent test accessibility across the entire vehicle, eliminating constant searching for a suitable ground point. A built-in flashlight aids work in dark conditions, while an audio tone indicator allows familiar users to navigate menus without looking away from the test point.

Features and Construction

The PowerScan PS100 combines multiple diagnostic functions into a single handheld tool. Its robust construction and long cable make it suitable for professional workshops and DIY use alike. The device includes an easy-to-read AVOmeter that displays voltage, current, and resistance at your fingertips.

Material and Build

The casing is made from durable plastic suitable for workshop environments. The 20-foot expandable cable is reinforced for repeated flexing and fitted with quality test probes and alligator clips. Circuit breaker protection ensures the tool remains safe during overload conditions.

Size and Practical Fit

The tool is compact enough to hold in one hand while probing with the other. Its 20-foot cable unfolds to a full 6 metres, allowing you to reach the furthest corners of a standard car without extension leads. The built-in flashlight is positioned to illuminate the probe tip area.

Uses and Placement

The PS100 is designed for automotive electrical diagnostics, from checking battery circuits to powering components for functional testing. Its long cable and flashlight make it suitable for both under-bonnet and interior cabin work.

Event or Professional Use

Professional mechanics can use the PowerScan to quickly diagnose wiring faults, short circuits, and poor grounds without wasting fuses. The ability to activate components like cooling fans and relays directly from the probe tip speeds up troubleshooting in busy workshops.

Everyday Home Use

DIY car enthusiasts will appreciate the intuitive colour-coded circuit identification (positive/negative/open) and the built-in continuity test for switches and relays. The 20-foot cable means you can test from the engine bay to the rear lights without moving the tool’s ground clip.

Benefits and Buying Value

This tool reduces diagnostic time by providing instant polarity checks and component activation without extra jumper wires. Its circuit breaker protection and built-in flashlight add practical value for everyday use.

Reuse and Low Maintenance

The circuit breaker resets after overload, so no replacement fuses are needed. The long cable and robust construction are designed for repeated daily use in a workshop or garage. The audio tone indicator allows hands-free menu navigation once you learn the tone assignments.

Why Choose This Product

The Autel PowerScan PS100 eliminates the need to reconnect battery clips for polarity testing, saving time and reducing errors. Its integrated AVOmeter, flashlight, and 20-foot cable provide a comprehensive diagnostic solution in one package, suitable for both professionals and home mechanics.
