Automotive Digital Circuit Tester – Low Voltage Diagnostic Tool This automotive circuit tester is designed for diagnosing lowvoltage electrical issues in a wide range of vehicles and machinery. Built for precision and ease of use, it helps identify faults quickly while protecting sensitive electronics from damage. Key Features and Benefits: Efficient LowVoltage Testing: Detects voltage and power failures in automotive electrical systems, helping locate faults in fuses, wiring, and components. Quick and Clear Digital Display: Integrated LED indicators visually confirm test results. Green light signals a positive test connection, red light signals a negative test connection. Wide Voltage Range Compatibility: Suitable for systems operating at 3V, 6V, 12V, 24V, and 48V – ideal for use with cars, trucks, motorcycles, electric vehicles, and construction machinery. Spring Wire Design for Convenience: Coiled cable expands from 255mm to 2.3m, making it easy to reach different parts of the vehicle while remaining compact for storage. Sensitive NeedlePoint Tip: Designed for precise contact during testing, reducing the risk of damage to wiring or connectors. Hands Operation: Durable alligator clip provides secure attachment, allowing you to work more efficiently without holding the tester in place. Strong Internal Spring Mechanism: Ensures quick response and accurate readings in various testing conditions. Clear Usage Guidelines for Safety: Designed to measure intermittently using the touch method; avoid applying power for more than 3 seconds to protect the internal circuit board. Damage caused by improper use is the responsibility of the user.
