Autel PowerScan PS100 Automotive Electrical System Diagnostic Tool

👍 Upgraded Power Circuit Probe Kit 2.0
Autel PowerScan PS100 is an all-in-one electrical tester that helps reduce diagnostic time. It supports:

• Voltage & polarity testing

• Continuity testing & signal circuit detection

• Component activation (in-hand, in-vehicle, with ground)

• Trailer light and connection testing

• Short circuit & open circuit tracing

• Ground fault detection

• Voltage drop testing with red/green LED indicators

• Built-in circuit breaker protection

• 20ft main cable + 20ft extension cable

Compared with traditional test lights or multimeters, PS100 provides faster, more intuitive diagnostics with extended data display (AC/DC voltage, resistance, diode), and supports active component testing.👍 4 Advanced Modes – Fast & Accurate Results
Switch between 4 working modes via the Mode button. Simply contact the probe to the circuit and view instant results on the LCD:
1️⃣ DC Voltage Mode – Reads DC voltage with 0.1V resolution
2️⃣ AC Voltage Mode – Displays Max/Min voltage, frequency, and duty cycle, useful for checking ECM signals
3️⃣ Resistance Mode – Measures resistance between probe tip and ground lead; ideal for checking fuses, wiring continuity, and switches
4️⃣ Tone On/Off Mode – Indicates working status; can be turned off to avoid noise interference👍 Component Activation Function
PS100 can test positive, negative, and open circuits, and perform continuity checks, circuit diagnostics, and ground testing.
It can also activate components directly to verify their condition, such as:

• Lights

• Motors

• Wipers

• Radiator fans

• Relays

No jumper wires required, making diagnostics safer, faster, and easier.

👍 Professional Continuity & Signal Circuit Tester

• Resistance Mode: A solid connection shows “0.0Ω” with green LED; “OL” indicates an open circuit

• Allows testing without disconnecting wires (probe can pierce insulation)

• Power Switch Test: Applies voltage for low-resistance circuit testing, ideal for ground checks

• Signal Test (AC Mode): Displays real-time Max/Min voltage, frequency, and duty cycle to verify sensor performance

👍 Short Circuit Detection & Overload Protection
The built-in resettable circuit breaker helps quickly locate short circuits by applying voltage along the wiring.

• Saves time and protects fuses

• Built-in 10A circuit breaker prevents overload

• Automatically cuts power and emits a warning buzzer when overloaded

• Resets automatically after tripping to ensure safety

👍 Instant Polarity Identification & High-Sensitivity Probe

• Quickly detects positive, negative, and open circuits

• Red LED + beep = positive

• Green LED + low tone = negative

• No light = open circuit

• Accurate voltage drop detection with LED + LCD display

• Sharp stainless steel probe easily pierces wires and reaches tight spaces
