Intelligent test

Mainly used for quick testing with no need to switch between different test modes. It can automatically identify the signal under test and display the voltage or ohmic value. Main test functions: voltage test, resistance test, positive and negative test.

Multimeter mode

This digital display intelligent multimeter can meet all the functions of the vehicle multimeter [DC voltage (VDC), resistance (OHM), diode / on/off test (DIO), current (AMP), frequency (HZ)], as well as continuous testing of circuits or components of the vehicle circuit system, which brings great convenience to the user.

Oscilloscope Mode

AUTOOL BT280 circuit tester supports sampling interval setting. The supported voltage test range is: 1V~100V. Function button "START/STOP" (press "OK" to start or stop waveform refresh); "DIV", the test range of each grid voltage is 1V-100V. Press the "UP" and "DOWN" keys to adjust the voltage value with one key.

Short circuit tracking and location

In most cases, a short circuit will manifest itself as a blown fuse or a tripped electrical protection device (such as a tripped circuit breaker). The AUTOOL BT280 circuit tester can diagnose and locate the cause of short circuits in circuits.

Test Procedure:
Connecting the tool to the positive and negative battery terminals. Press the button to the "-" side, the LED should glow red and provide positive voltage. Remove the blown fuse from the fuse box and trace from the two terminals of the fuse socket. Use the probe to make quick contact with the wire. If the LED turns green and the buzzer sounds, it indicates a short circuit or overload component on this side, please note the color or identification code of this wire.Follow the wires along the harness as far as possible to find the color-coded wires in the harness and expose them. Then cut the wire, follow the direction of the shorted wire and repeat the process until you find the short. If there are components in the back of the wire, check the components separately for good condition.

Component activation

The Component Activation function is designed to generate an activation signal to the component under test, such as activating on-board electrical tools such as lights, motors, etc. (To avoid burning the components, please refer to the specifications and parameters of the components, and then set the overload current value)

Provide 0-5V power supply

The 0-5V power supply mode of AUTOOL BT280 is designed as active mode, but the function is different from the component activation mode. The tool can regulate the voltage output below 5V and limit the current below 100mA. (This is a safe range of current and voltage to avoid burning out electronic components).

Injector Test

The AUTOOL BT280 circuit detector can feed different pulse signals to the injector and provide 4 pulse modes to better detect the condition of the injector.

Relay test

The AUTOOL BT280 circuit tester can perform the continuity test of the 5-terminal relay and the 4-terminal relay through the matching special test terminal.

Available in 18 languages.

Multi-language feature options. It supports 18 languages including English, Spanish, German, French, Italian, Portuguese, Simplified Chinese, Polish, Russian, Vietnamese, Thai, Indonesian, Filipino, Malay, Arabic, Korean, Japanese, and Traditional Chinese.

2.4-inch display

2.4-inch LCD large color screen with nine-square division design. The large backlit screen avoids situations of completing the detection in dark areas, helping car technicians, engineers or car DIYers view readings more easily. Moreover, the display screen is clearer, and the displayed data is more direct and clear.

Double automatic circuit breaker protection

  • Short-circuit automatic protection function (the threshold can be adjusted, overload can be set by yourself). In case of detecting current overload at work, AUTOOL BT280 tool can disconnect power automatically to protect vehicles and tools as well as to guarantee the safety of electricity and reduce unnecessary losses.
  • Fusing the fuse. The auxiliary grounding lead is equipped with a 20amp blown fuse to protect the equipment from power failure when there is a short circuit or overload.
