An LCR meter measures inductance (L), capacitance (C), and resistance (R).
Some of the key features to look for in an LCR meter (also known as an impedance meter) are: accuracy, test frequency, measured parameters, test voltage and test current. Additionally, an easy to understand display of test results and the ability to access and use these results has become increasingly important. Component testing often requires much more than simply a resistance, capacitance or inductance value at a given test frequency and stimulus voltage. LCR meters and impedance meters must have the flexibility to provide multi-parameters over wide frequency and voltage ranges.
