Autool BT280 | Circuit tester
The Autool BT280 is a circuit tester for diagnosing electrical systems in vehicles with a 9V to 30V system. The device is equipped with a 2.4 inch TFT color screen for displaying measurement values. The tester has a measurement range for voltage from 0.1V to 100V, for resistance from 1Ω to 200kΩ, and for current from 0A to 18A. The power cable is 6 meters long.
The BT280 features multiple modes, including a multimeter mode for measuring voltage, resistance, current, frequency, and for performing diode and continuity tests. The oscilloscope mode enables a graphical display of signals. Additional functions include a relay test, an injector test, component activation, and an adjustable 0-5V power supply. The smart mode automatically detects voltage and resistance. The system is protected with an adjustable circuit breaker.
Application and functionality:
The BT280 is designed for performing measurements and tests on vehicle electrical circuits. The functions support identifying issues such as short circuits, open circuits, and component operation.
- Multimeter mode: For performing standard electrical measurements, including DC voltage, resistance, current, frequency, diode, and continuity tests.
- Oscilloscope mode: Visualizes electrical signals in a graph, which helps in analyzing sensor signals and data lines.
- Component activation: Can supply components such as lamps, motors, and relays with voltage or ground to check their operation.
- Relay test: Test the functionality of automotive relays by following the diagram on the screen.
- Injector test: Offers four test modes for analyzing the operation of fuel injectors.
- 0-5V power supply: Provides an adjustable output voltage between 0 and 5 volts for testing sensors and ECU circuits.
- Smart mode: Automatically identifies the voltage or resistance present on the test probe without manual setting.
Measurement ranges and functions:
The device offers specific measurement ranges and test capabilities for detailed diagnostics.
- DC voltage measurement: Measurement range from 0.1V to 100V.
- Resistance measurement: Measurement range from 1Ω to 200kΩ.
- Current measurement: Measurement range from 0A to 18A, with an adjustable current breaker for protection.
- Frequency measurement: Measurement of the frequency of electrical signals.
- Polarity test: Identifies positive and negative circuits and indicates this visually and audibly.
