MultiFunction Automotive Circuit Tester Designed for accurate, efficient, and comprehensive electrical diagnostics, this multifunction automotive circuit tester is an essential tool for vehicle maintenance and troubleshooting. Built for professionals and enthusiasts alike, it delivers precise results for a variety of testing needs. Key Benefits and Features: Versatile Testing Capabilities: Measures battery voltage, checks voltage polarity, tests conductivity, inspects lamps and motors, and identifies electrical faults such as short circuits and poor grounding. Extended Reach: Equipped with a 4.5meter detection cable, allowing you to access both the front and rear of the vehicle without repositioning. Ideal for fullvehicle circuit checks. Clear Readings: LCD display shows voltage readings from 3.5 V to 36 V for quick, easy analysis. Displays accurate values directly on screen. Suitable for a wide range of automotive applications. Not for AC or voltage sources exceeding 36 V. Fast and Precise Detection: sensitivity probes ensure rapid fault identification. Quickly locate wiring problems without the need for timeconsuming manual inspection of every wire. TimeSaving Performance: Streamlines electrical diagnostics, reducing time and simplifying complex wiring inspections. Product Specifications: Voltage Range: 3.5 V to 36 V DC Cable Length: 4.5 meters Display: visibility LCD Probe Type: sensitivity detection probe Application: Automotive electrical systems only (DC) Practical Use Scenarios: 1. Battery Health Check – Instantly measure battery voltage to determine condition before starting repairs. 2. Fault Location – Quickly identify wiring faults in headlights, tail lights, or motor circuits to speed up repairs. 3. Complete Circuit Testing – Use across the entire vehicle from front to back with the extended cable for efficient inspection. Ease of Use: Connect the red clip to the battery's positive terminal and the black clip to the negative terminal for an immediate voltage reading. Switch on the front light to perform further visual checks in lowlight conditions. Inverse connection of clips will prevent voltage display but will still power the inspection lamp, allowing flexible and straightforward operation. This automotive circuit tester delivers reliability, accuracy, and convenience, making it an indispensable tool for diagnosing and repairing vehicle electrical systems.
