- Quick and efficient tool designed for testing automotive relays to easily determine their operational status. - Connect the tool directly to your car battery (11V-15V) to accurately assess relay functionality. - Monitors critical data such as closing time and relay inertia across each testing phase. - Visual indicators simplify results: a green light signals successful tests, while a red light highlights any failures. This ensures quick and straightforward diagnostics of automotive relay conditions. - Specifically engineered to verify the correct opening and closing functions of relays. - Red LED activation indicates an abnormal relay condition, while a green LED confirms normal function. Practical applications: - Ideal for automotive technicians conducting routine checks on vehicle relay systems. - Essential for DIY car enthusiasts needing to troubleshoot electrical issues efficiently. - Beneficial for fleet maintenance managers ensuring vehicle reliability and safety through regular relay testing.
