A LCR meter is a piece of electronic test equipment used to measure, among other things, the impedance (inductance, capacitance, resistance) of a component.
Usually the device under test (DUT) is subjected to an AC voltage source, then the voltage over, and the current through the DUT are measured. The measured impedance consists of real and complex components. The phase angle (Φ) also is an important parameter.
