12V/24V

Why do customers need an automotive circuit tester? The types and causes of automotive circuit failures are diverse, and the circuit systems are complex. This makes it much more convenient to have an automotive circuit tester to accurately detect and diagnose various wiring faults in the car's wiring, as well as aging wiring and other conditions. Meanwhile, the circuit tester can also detect possible future failures of the automotive circuit systems and provide reliable information for troubleshooting. Why do customers choose AUTOOL BT250 automotive circuit tester? As compared to a multimeter, the AUTOOL BT250 only requires pressing the mode button and selecting the diagnostic mode, then the probe tip is in contact with the circuit and the display will show DC/AC voltage, resistance and other data. The BT250 inspection cable is 1.5 meters in length and can cover the entire engine compartment of the vehicle. The BT250 is also equipped with activation components, signal circuit testing, headlight testing, multi-language function options, etc. The BT250 is tailored for automotive circuit system testing and will be more efficient in determining circuit system problems. Support multi-language selection With multi-language feature options, it supports eight languages: English, German, French, Spanish, Italian, Portuguese, Russian, and Chinese. Supports multiple test modes 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. Clear indicator light Red/green polarity indicator (red/green indicator is displayed in the case of positive/negative and different modes of testing). Positive, negative, or open circuits can be identified. The red indicator lights up when the tip of the device probe contacts a positive circuit; the green indicator lights up when the tip of the device probe contacts a negative voltage or negative voltage circuit. It's an ideal working guide to help facilitate inspection operations. Built-in flashlight Built-in LED flashlight provides illumination for small spaces in the vehicle, allowing users to perform smooth circuit testing even in dark environments. Its brightness is sufficient to illuminate the work area and provide a more comfortable working environment for the user. If unnecessary, the flashlight and the sound buzzer can be turned off. Overcurrent protection When the current overload is detected, the AUTOOL BT250 circuit tester will automatically disconnect the power supply to protect the ECU and electrical safety of the car and reduce unnecessary losses. Handy & Easy Operation All-in-one body with compact size is more ergonomic overall. The inspection cable is 1.5m in length and can cover the entire vehicle engine compartment, enabling easy inspection of the car's circuit system.
