LCR meters and decade boxes are used to measure inductance (L), capacitance (C), and resistance (R). They are able to take precision measurements of components. Measurement using LCR decade boxes is taken with a power of ten, hence the name. Using these instruments, the values of individual components, such as resistors in experimental assemblies, can be determined precisely. LCR meters also have high-contrast LCD displays, as well as other features such as integrated measured value memory or a USB interface for connection to a computer.
