LCR meters used to be relegated only to professional design labs. Not any more. This portable LCR meter makes it easy for you to analyze the analog performance of virtually any device under test, whether in your lab or on the job. The dsPIC30F4012-based meter uses DDS techniques and DSP methods to condition the resulting voltage and current signals. Its handy user interface and graphic LCD make it easy to operate and read.
The project its cool and it is a great debugging tool for any electronics lab, but i still like more the commercial LCR tweezers.

As you may know LCR meter’s are included in those fancy measuring instruments that are always to expensive to be used at home for hobby. So if you need to analyze the performance of an analog device you basically have two options: either you borrow a LCR meter from a friend that has one or you build one. If you decide to build one, you will benefit from it whenever you are going to need it so it might be a good idea to have one of these meters around. Me personally i never used one, neither needed one.
