About this item

  • 【2026 All-in-One circuit relay tester】The ultimate diagnostic tool for 6-30V vehicle electrical systems, featuring a high-resolution 160x128 TFT display for crystal-clear readings. Trust Autel's industry-leading accuracy for: Voltage & Polarity Verification; Continuity & Circuit Integrity Checks; Signal Circuit Analysis; Component Activation Testing; Ground Fault Detection; Short Circuit Localization; Circuit Breaker Protection Testing.
  • 【4 High - performance Working Modes】Optimize your circuit diagnostics with four adaptive modes: 1. DC Voltage Measurement: Measures DC voltage with a resolution of 0.1V 2. Resistance Testing: Effortlessly gauge resistance between probes, ideal for fuse continuity checks, open circuit detection (displays "OL"), and switch functionality verification 3. AC Voltage Analysis: Displays maximum voltage, minimum voltage, frequency, and duty cycle 4. Tone Activation/Deactivation: Technicians can use the tone in low - light conditions to identify test results and turn it off when not needed.
  • 【Component Activation】The Autel PS100 power circuit tester simplifies diagnostics by efficiently testing positive/negative polarity, open circuits, and continuity—ideal for identifying circuit faults, evaluating ground integrity, and reading AC/DC current to activate in-vehicle or off-vehicle components. It also monitors MIN/MAX voltage fluctuations, enabling precise analysis of electrical systems.
  • 【Voltage & Polarity Detection】The Autel PS100 automotive circuit testing probe set offers intuitive, step-by-step guidance for identifying voltage levels and polarity. Positive Circuit Contact: Touch the probe tip to a positive terminal, triggering the red LED indicator and displaying voltage readings on the LCD with 0.1V resolution. Negative Circuit Contact: Connect to a negative terminal to activate the green LED, with the same 0.1V resolution on the display.
  • 【CONTINUITY & SIGNAL CIRCUIT TESTING】The Autel Electrical System Probe Tester enables rapid, precise diagnostics of sensor circuits and connectivity faults with two intuitive continuity testing methods: Resistance Mode & Power Mode. Ideal for assessing circuit integrity, this tool simplifies detection of open circuits, faulty connections, or shorts—essential for maintaining electrical system reliability in automotive diagnostics.
  • 【20FT EXTENSION CABLE & INTEGRATED FLASHLIGHT】The Autel automotive electrical tester enhances accessibility with a 20ft extension cable (in addition to its standard 20ft cable), enabling testing at any vehicle location—perfect for trailer wiring setups. Equipped with a built-in flashlight, the tool ensures optimal visibility in dark or low-light environments, making nighttime diagnostics or work in dimly lit areas more efficient.
