Frequently Asked Questions

Q: What does the inductance coil tester detect on a phone motherboard?

A: The inductor coil tester uses electromagnetic induction to test whether inductance coils (inductors) on a phone motherboard are functioning correctly. It can help identify faults related to charging circuits, power-on failures, and other motherboard-level electrical issues by lighting up its green LED when a coil is working properly.

Q: How do I power the inductance coil tester?

A: The tester is powered via a USB Type-C port, making it easy to connect with any modern USB-C cable. Simply plug it in, touch the probe tip to the inductor coil on the motherboard, and check the LED indicator for a result.

Q: Is this tester suitable for beginners or only professional repair technicians?

A: While it's a professional-grade tool, its simple plug-and-test design makes it accessible to beginners as well. There's no complex setup or calibration — just connect and test. Its ergonomic, lightweight design and clear LED indicator make diagnostics straightforward even for those new to motherboard repair.

Q: Can this tool be used on motherboards other than phone motherboards?

A: The tool is specifically designed and optimized for mobile phone motherboard inductance coil testing, but it can also be used on other small electronic circuit boards that contain inductance coils, such as tablets or small consumer electronics, as long as the component size is compatible with the probe tip.
