LCR meters are measuring instruments that measure a physical property known as impedance. Impedance, which is expressed using the quantifier Z, indicates resistance to the flow of an AC current. It can be calculated from the current I flowing to the measurement target and the voltage V across the target’s terminals.

There are two LCR meter types viz. benchtop and handheld. Benchtop are developed for bench applications and hence are kept at fixed location without much of movement. Handheld are developed for portable applications and hence can be moved around for test and measurement purpose.

An LCR meter is a type of electronic test equipment used to measure the inductance (L), capacitance (C), and resistance (R) of an electronic component. In the simpler versions of this instrument the impedance was measured internally and converted for display to the corresponding capacitance or inductance value
