Precision AVR Inductance/Capacitance Meter

L/C/CE Meter – Precision Inductance, Capacitance, and Electrolytic Capacitor Meter

Measure L, C, and CE electrolytic capacitors with high accuracy. The L/C/CE Meter is a versatile, open-source handheld instrument designed for measuring inductance (L), capacitance (C), and electrolytic capacitors up to 10,000 µF with exceptional precision. Perfect for electronics hobbyists, repair technicians, and engineers.

Why choose this meter?

Unlike cheap multimeters with limited capacitor range, this dedicated L/C/CE meter covers everything from tiny 1 pF ceramic caps to large 10,000 µF electrolytic and tantalum capacitors. It also measures inductors from 0.1 µH to 1 H, making it an indispensable tool for any electronics workbench.

Key Features:

✅ Wide Measurement Ranges

Inductance (L): 0.1 µH – 1 H

Capacitance (C): 1 pF – 10,000 µF (includes electrolytic and tantalum capacitors)

✅ High Accuracy & Smart Features

Calibration menu for precise readings

Compensation menu for lead and parasitic cancellation

Three modes toggle: L / C / CE

Auto-ranging – automatically displays nH, mH, H and pF, nF, µF

Stable and reliable readings

✅ Display & Power

Clear 2 x 16 LCD display

Compact, portable design

Powered by 9V–12V DC via standard 2.1mm jack

✅ Open Source

Fully documented on OSHWLab
