LCR Meters

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.

White Paper: LCR Measurement Primer

What is Impedance? What are the measurements of Impedance? This primer defines and explains the measurement of the impedance parameters known as L (inductance), C (capacitance), and R (resistance). Impedance parameters are characteristic of an AC circuit; this primer describes the impedance measurements that are typically used, including their equations. Also described are the connections to the device under test, and how to use test instruments to precisely measure impedance. In addition, primer describes the testing of individual passive components for inductance, capacitance, and resistance.
