- Quick fault detection: This motherboard coil tester uses electromagnetic induction technology to instantly identify faulty inductors. Place the component on the testing area and press the button. Green light means a good inductor; no light signals a fault. Much faster than traditional multimeter testing for motherboard repair and electronic maintenance. - User-friendly operation: No professional skills or technical knowledge required. The one-touch design makes testing accessible to both hobbyists and professional repair technicians. Immediate results help pinpoint circuit-board issues without complicated settings, saving diagnostic time. - Compact portable design: The blue PCB tester fits easily into any toolbox or repair kit for convenient testing anywhere. Its lightweight construction and compact size make it ideal for on-site electronic repairs, workshop diagnostics, or bench testing of circuit boards and power supply components. - Wide compatibility: Works effectively with various inductors found in motherboards, power supplies, and electronic devices. The testing mechanism accommodates different coil sizes and types commonly used in PCB assemblies, making it versatile for multiple repair scenarios and component verification needs. Use scenarios: - In a repair shop, quickly verify inductors on a motherboard or PSU to determine if replacement is needed. - On-site service for laptops or desktops, testing inductors during field diagnostics to speed up repair decisions. - DIY electronics projects or salvaged-board testing to confirm coil integrity before reassembly.
