Autool BT280 Circuit Tester

The Autool BT280 is an advanced and multifunctional circuit tester, designed for diagnosing electrical systems in vehicles with a voltage range of 9V to 30V. The device combines the functionalities of a multimeter, oscilloscope, relay and injector tester, and component activation tool in one compact design. With a 2.4-inch TFT color display and a cable length of 6 meters, the BT280 offers both ease of use and flexibility for various applications in cars, trucks, motorcycles, and other vehicles.

Thanks to the smart detection mode, the BT280 automatically identifies voltage and resistance signals and displays them clearly on the screen. The integrated LED indicators immediately show the polarity of the tested circuit, contributing to efficient and accurate diagnosis.

Features:

• Smart detection mode: Automatic identification of voltage, resistance, and polarity, with clear display on the screen and LED indicators.

• Multimeter function: Measurements of DC voltage (0.1–100V), resistance (1–200 kΩ), current (0–18A), diodes, and frequency, suitable for various electrical tests.

• Oscilloscope function: Visualization of waveforms, including amplitude, frequency, and time, for detailed analysis of electrical signals.

• Relay and injector test: Testing 4- and 5-pin relays, as well as fuel injectors with four different pulse modes, to evaluate operation and response.

• Component activation: Three activation modes (direct, locked, pulse) to test components such as lights and motors for functionality.

• Adjustable power supply: Output voltage adjustable between 0–5V with a current limit of 100 mA, ideal for simulating ECU/ECM signals.

Special features:

• TFT color display: 2.4-inch screen with a resolution of 320x240 pixels, for clear and distinct display of measurement data.

• Built-in LED lighting: For optimal visibility when working in dark or poorly lit environments.

• Safety features: Equipped with an internal 20A fuse and voltage alarm to protect both the device and the vehicle from overload and short circuit.
