Accurate Inductance Measurement Made Easy
Measuring inductance is essential for electronics enthusiasts and engineers working with coils and transformers. This self-meter circuit allows you to measure the inductance of any coil using a standard analog or digital multimeter.
How It Works
This circuit converts the inductance of a coil into a measurable voltage, which can be read directly on a multimeter. It provides inductance readings in microhenries (μH) or millihenries (mH), covering a range from 10 μH to 100 mH across three selectable scales:
- 1 mH range for small inductors
- 10 mH range for medium-sized coils
- 100 mH range for larger inductors
Key Features of the Self-Meter
✅ Wide Measurement Range – Covers inductances from 10 μH to 100 mH.
✅ Compatible with Any Multimeter – Works with both analog and digital meters.
✅ User-Friendly – Simple circuit design with easy calibration.
✅ Cost-Effective – Eliminates the need for expensive LCR meters.
Why Build This Self-Meter?
This project is perfect for hobbyists, students, and professionals who need a reliable way to measure inductance without investing in specialized equipment. It’s an excellent tool for designing and troubleshooting circuits involving inductors.
