Autool BT260 Automotive Circuit Tester Tool

The Autool BT260 just needs a simple press on the mode button to display data namely DC/AC voltage, resistance, etc, select the diagnostic mode and touch the probe tip to the circuit. The inspection cable of BT260 is 10 meters in length and can cover the entire vehicle. Also support functions of activating components, signal circuit test, headlight test, multi-language and so on. BT260 is designed for automotive circuit system inspection, and can find circuit system problems more efficiently.

Supports multiple test modes:

The Autool BT260 circuit tester can perform all types of tests such as DC voltage test, AC voltage test, resistance and diodes test etc. It adopts the newly improved functions to test signal frequency, and duty cycle, which can help service technicians track and identify problem circuits as well as rule out bad ones, speeding up the diagnostic process and making it easier to find the true cause of a circuit problem.

• DC voltage detection mode, used to detect the voltage value of the circuit under test.
• AC voltage detection mode, used to detect the maximum voltage value and minimum voltage value, power frequency and duty cycle of the circuit under test.
• Resistance detection mode, used to detect the resistance value between the probe of the circuit under test and the auxiliary ground wire.
• Diode test mode to quickly test the working condition of diode components and determine open circuits and continuity.

• Voltage and Polarity Test:
• Continuity test. 
  
• Signal circuit test. 
  
• Activate components in the vehicle test.
• Active component with ground test.
• Test headlights and connections.

Note: Users can use the probe tip to test the plastic insulation on the wire, which means that the circuit can be tested without disconnecting any connections.

Short circuit tracking and location: In most cases, a short circuit of a component or a momentary overload will cause a fuse or circuit to blow and a circuit breaker to trip.

Test Procedure: Connect the red clip to the positive of the vehicle battery and the black clip to the negative of the vehicle battery; 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. If the LED glows 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, find the color-coded wire in the harness and expose it, 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.

Clear guidance of indicator light: Red/green polarity indicators (Positive/negative and tests in different modes show red/green indicator lights) identify positive, negative or open circuit. When the tool probe tip touches the positive circuit, the red indicator lights up; when the tool probe tip touches the negative voltage or negative voltage circuit, the green indicator lights up. It is an intimate work guide, which makes the inspection operation more convenient and smoother.

HD display: Modern and outstanding LCD high-definition color display. The large backlit screen avoids situations of completing the detection in dark areas, helping car technicians, engineers or car DIYers view readings more easily. 

Super long detection line: The inspection cable is 10 meters in length.

Suitable for all 9V to 30V automotive electrical system diagnostics:

1. Enable users find whether an automotive circuit is positive, negative, or open without reconnecting clips from one battery pole to another.
2. Use the built-in auxiliary ground wire to test the continuity.
3. Conduct positive or negative battery current to the probe tip by pressing the power switch to test the functionality of electrical components. No need to use jumper wires.
4. Immediately test for poor ground connections, no need to perform a voltage drop test.
5. Track and locate short circuits without over-using fuses.
6. The tool's extra-long cable allows users to test along the entire length of the vehicle.
