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. 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. Circuit diagram of a Q-meter is shown is figure. A wide-range os­cillator with frequency range from 50 kHz to 50 MHz is used as a power supply to the cir­cuit. The output of the oscillator is shorted by a low-value resistance, R sh usually of the or­der of 0.02 ohm. So it in­troduces almost no resistance into the oscillatory circuit and ...

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. The Extech Instruments Division is a manufacturer and supplier of 15 major product categories of technically advanced, portable meters including multimeters, clamp meters, electrical testers, and environmental meters for the measurement of light, sound, temperature, humidity, airflow, RPMs, and water quality. The AC output voltage of an LCR meter has to match it. Accuracy. If the accuracy of your measurement is high, it takes more time to record that measurement for the LCR meter. Accuracy is hampered if the measurement is recorded in a short time. Most LCR meters provide 3 speeds for measurement: slow, medium, and fast.
