Autel PowerScan PS100 Automotive Circuit Tester

Autel PowerScan PS100 is a professional automotive circuit tester and electrical diagnostic tool designed for 12 V and 24 V vehicle electrical systems. It combines voltage, current, and resistance measurement, continuity testing, ground testing, component activation, polarity identification, and circuit fault tracing in one compact handheld tool.

PS100 connects directly to the vehicle battery, allowing the technician both to measure electrical circuits and to apply power or ground directly to a component under test. This makes it fast and convenient to test relays, cooling fans, motors, lamps, and other electrical components without separate jumper wires.

The included 20 ft extension cable provides access throughout the vehicle, while the integrated circuit breaker helps protect the tool and components against overload.

Features

• 12 V / 24 V electrical systems — Suitable for passenger cars, vans, and other vehicles using 12 or 24 volt electrical systems.
• AVOmeter — Measures voltage, current, and resistance.
• DC and AC voltage measurement — Enables versatile electrical system testing.
• Polarity identification — Quickly identifies positive, negative, and open circuits.
• Continuity testing — Checks continuity of wiring, switches, relays, and diodes.
• Ground testing — Quickly identifies good and poor ground connections.
• Power injection — Supplies direct power or ground to the component being tested.
• Component activation — Suitable for activating relays, fans, motors, and other 12/24 V electrical components.
• Short circuit tracing — Helps locate circuit and wiring shorts without repeatedly replacing fuses.
• MIN / MAX voltage sensing — Helps identify intermittent voltage drops and spikes.
• Circuit breaker protection — Integrated protection helps protect the tool and tested components against overload.
• Built-in flashlight — Makes it easier to work in dark engine compartments and vehicle interiors.
• Audio tone indicator — Provides audible feedback for faster operation without constantly watching the display.
• Long test cable — Includes an approximately 20 ft / 6 m extension cable for convenient access around the vehicle.

Please note

• PS100 is intended for low-voltage 12 V and 24 V automotive electrical systems.
• Do not use the tool on high-voltage EV or hybrid vehicle circuits.
• Before using the power injection function, always confirm the rated voltage and correct polarity of the component being tested.
• Do not apply external voltage to ECU signal or communication circuits unless specifically instructed by the vehicle manufacturer.
• The integrated circuit breaker provides overload protection, but correct electrical diagnostic procedures must always be followed.
