Introduction:

M181 LCR meter is a practical kit for measuring the R, C, or L of either through-hole or surface-mount components. It features about 1% accuracy, which is adequate in most engineering scenarios. Not only being very easy to build, it also includes a Self Test mode that helps users to verify the correctness of assembly. Compact in size and the capability of serial output make the meter a great choice for many embedded applications.
