• Precise Measurement: It can accurately measure the standard current of household and commercial vehicles. With high precision, it can detect minute current changes, helping you quickly and accurately identify circuit faults. Even circuit testing novices can easily perform professional-grade current testing.
• Professional Automotive Tool: Precise Current & Circuit Diagnostic.As a versatile automotive tool (integrating relay tester and circuit breaker finder functions), this high-precision current tester accurately measures standard currents for passenger and commercial vehicles. It detects tiny current fluctuations to quickly locate electrical probe faults and parasitic draw issues — even beginners can easily perform professional-grade circuit diagnostic tests.
• Versatile Application: Suitable for various circuit testing needs in both passenger and commercial vehicles, it can handle everything from troubleshooting minor issues in family cars to performing complex circuit tests in commercial trucks. Its compact size and lightweight design make it easy to carry and adapt to different situations.
• Clear Data Reading: Current Cable Locator with Backlit Display.The blue backlit LCD screen (paired with current cable locator functionality) ensures current data is readable in bright or low-light conditions — no subtle fluctuations are missed. Combined with the built-in flashlight, it keeps both test data and the operating area visible at night, supporting voltage continuity checks.
• User-friendly design: Made of non-slip ABS/PC material with an outer rubber coating, this product not only enhances its durability but also provides a comfortable and secure grip, reducing fatigue during extended use. It supports long-lasting 23A battery power, allowing for multiple tests on a single charge, eliminating the need for frequent battery replacements.
