Autel PowerScan PS100 Power Circuit Tester | 12-24V Automotive Open/Short Finder | 40ft Reach

Powerful, portable electrical diagnostics for 12-24V systems

The Autel PowerScan PS100 Black High-tech Version is a compact, all-in-one tool designed to streamline electrical troubleshooting on most 12-24V vehicle networks. With a rugged build, extended reach, and clear visual cues, it helps you move from guesswork to informed checks, whether you’re in a shop bay or on the road.

Built to handle a wide range of automotive circuits, the PS100 enables quick voltage checks, polarity identification, resistance reading, and targeted component activation. Its thoughtful design supports both professional technicians and dedicated DIY enthusiasts who want dependable readings without dragging along multiple tools.

Four diagnostic modes for flexible testing

Switch between modes to match your task. In DC voltage mode, you’ll see readings with precise 0.1V resolution. AC voltage analysis captures real-time min/max values, frequency, and duty cycle for fluctuating signals. The resistance mode reveals impedance between the probe tip and ground. A smart audio-visual prompt confirms status, even in dim spaces.

• DC voltage mode with precise 0.1V steps
• AC voltage analysis for dynamic circuits
• Resistance measurement for path integrity
• Contextual tones and LED cues for fast decisions

Component activation and comprehensive circuit tests

Effortlessly activate and verify electrical components to determine if they’re healthy. Typical tests include in-vehicle systems like HVAC motors, power windows, wipers, and rear defrosters, plus lighting circuits (headlights, indicators, brakes) and powertrain elements (fans, injectors).

• In-vehicle system testing: blower, windows, wipers, defroster
• Lighting system checks: headlights, turn signals, brake lights, trailer lamps
• Power system diagnosis: motors, fans, injectors

Short circuit tracking with built-in protection

Precisely locate shorts or break points, reducing the need for hours of meter-to-meter searching. An internal protection mechanism helps safeguard both you and the vehicle electronics during testing.

Polarity, continuity, and safe operation

Rapidly identify positive or negative polarity with intuitive LED indicators and verify continuity across switches, relays, diodes, fuses, and circuits for reliable troubleshooting.

Extended reach, illumination, and flexible power options

The PS100 features a total 40-foot reach (20 ft plus 20 ft extension) with a built-in LED flashlight for dim environments. It supports two power sources—cigarette lighter and car battery—and is designed to work with most multimeter cables, giving you versatile field capability.

Notes on use and support: Autel backs the PS100 with a 12‑month warranty, 24/7 online assistance, a 30-day worry-free return, and lifetime after-sales service. This tool is positioned as a practical, high-value option for technicians and enthusiasts who want clear readings and confident diagnostics.
