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.
