Car Circuit Probe Kit,12V 24V Automotive Circuit Tester Car Electrical System Test Tool Kit,AC DC Resistance Digital Voltage Tester,Short Finder,Relay Fuse Tester
- 【Widely Application】The circuit tester Suitable for all 9V to 30V automotive electrical system diagnostics 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.
- 【Continuity Test】AUTOOL BT260 circuit tester can carry out continuity test. Test Procedure: Unfold the cable and connect the red clip to the positive end of the vehicle battery and the black clip to the negative end of the vehicle battery; connect the auxiliary ground wire to one side of the test lead and the probe tip to the other side.f there is continuity in the vehicle circuit, the LED will glow green. If the LED does not glow, there is no continuity.
- 【Voltage and Polarity Test】Whencircuit tester is in the DC voltage mode, contact its probe tip to the positive circuit. The LED should glow red and LCD display will show the voltage data. If the tool's buzzer is turned on, a high-pitched tone will sound. Contact probe tip with the negative circuit, the LED should glow green and the LCD display will show voltage data. If the tool's buzzer is turned on, a low tone will sound. Neither LED will glow if its probe tip is connected to an open circuit.
- 【Signal Circuit Test】The AUTOOL BT260 circuit tester can easily test vehicle sensors. For example, a user who suspects a problem with the MAP sensor circuit can follow the procedure related to testing this sensor as follows : Set the BT260 to AC voltage mode, connect the grounded wire clip to the MAP sensor negative terminal, then connect the probe tip to the MAP sensor positive terminal and check the LCD display.
- 【Activate Components in the Vehicle】If the green LED light turns off or the circuit breaker trips suddenly, it indicates the tool is overloaded. This may be due to the following reasons: the contact being probed is a direct ground / the component under test is short-circuited / the component is a very high current component (i.e. the starter motor). If the circuit breaker trips, wait for it to cool down (15 seconds) and then press the reset button to reset.
- 【Test Headlights and Connections】When the AUTOOL BT260 circuit tester is in DC voltage mode, clip the auxiliary ground wire to the trailer ground, probe the connection at the jack, and apply voltage to the probe tip. The function and orientation of the connectors and trailer lights can be checked in this way.
- 【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. Moreover, the display screen is clearer, and the displayed data is more direct and clear.
- 【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 smooth.
- 【Support Multi-language Selection】Multi-language function options, support seven languages: English, German, French, Spanish, Italian, Portuguese, Russian
- 【Super Long Detection Line】The inspection cable is 10 meters in length and can cover from the vehicle's engine to the car's taillights, enabling easy inspection of the car's circuit system.
