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.

Supports multiple test modes The AUTOOL BT250 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. 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.

Support multi-language selection With multi-language feature options, it supports eight languages: English, German, French, Spanish, Italian, Portuguese, Russian, and Chinese. LCD color 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. 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.

No extra battery required AUTOOL BT250 only needs to be connected to the car battery, and it can start working, which is very simple and convenient.

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. Free switching of DC and AC power AUTOOL BT250 uses 12~24V DC power supply.

The BT250 can switch directly from one test mode to another easily and securely. It can also speed up the circuit troubleshooting and diagnostic process by pressing its mode button, and within 3 seconds, the BT250 will switch from digital to waveform displaying AC voltage, frequency, and duty cycle tests. 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.
