Inductance Tester | PCB Motherboard Coil Fault Detector Tool

Inductance Tester – Electromagnetic Induction Fault Detector for PCB & Motherboard Repair

Whether you're a seasoned electronics technician or a hands-on hobbyist, the Inductance Tester is your go-to tool for fast, accurate coil and inductor fault detection. Designed for diagnosing issues in PCB motherboards, phone mainboards, speakers, motors, and circuit components, this compact handheld tester streamlines your diagnostic workflow so you can identify faulty inductors in seconds — not minutes.

Key Features

• Type-C Powered: Simply plug in via a Type-C cable for reliable, uninterrupted power during testing sessions — no batteries required.
• Instant Visual Indicator: A built-in LED indicator lights up when the inductor is functioning normally, and stays off when a fault is detected — giving you clear, at-a-glance results.
• Ultra-Compact & Portable: Measuring approximately 7 × 3.5 cm and weighing just ~4g, this tester slips easily into any toolbox, pocket, or repair kit.
• Broad Compatibility: Works with coils, inductors, and electromagnetic components in phones, computers, speakers, motors, and general circuit boards.
• Simplified Workflow: No complex setup — plug in, press the button, bring the sensing end close to the component, and read the indicator. That's it.
• Durable Construction: Built from quality electronic-grade materials for consistent performance in workshop and field environments alike.

How to Use

1. Connect the Type-C power cable to the tester.
2. Press the button to activate.
3. Bring the sensing end close to the inductor or coil you want to test.
4. LED ON = Inductor is working normally. LED OFF = Inductor is faulty or damaged.

Frequently Asked Questions

Q: What does the inductance tester actually detect?

A: This inductance tester uses electromagnetic induction to check whether a coil or inductor on a PCB, motherboard, or circuit board is functioning correctly. When the sensing end is placed near an active inductor, the LED indicator lights up confirming normal operation. If the LED stays off, the inductor is likely faulty or damaged — allowing you to quickly pinpoint problem components without complex equipment.

Q: What devices can I use this coil tester on?

A: The inductance tester is compatible with a wide range of electronic devices and components, including smartphone and tablet motherboards, computer PCBs, speakers, motors, coils, and general circuit assemblies. It is ideal for electronics repair shops, DIY enthusiasts, and professional technicians who need a fast and portable diagnostic tool.

Q: Does the inductance tester come with a Type-C cable?

A: The package includes 1 × Inductance Tester. A Type-C cable (standard USB-C) is required for power — please use a standard USB-C cable you already have, as one is not included in the box.

Q: Is this tool suitable for beginners?

A: Absolutely. The tester is designed with a simplified workflow — just plug in, press the button, and hold the sensor near the component. The LED indicator provides an instant result with no need to read complex measurements or navigate multi-step menus, making it accessible for beginners and seasoned technicians alike.
