LCR Meter category for high-precision measurement of capacitance (C), inductance (L), and resistance (R) of electronic components and circuits. Used in manufacturing for electronic component quality control, circuit design verification, and electronic device characteristic evaluation. Supports characteristic measurement of passive components such as capacitors, coils, and resistors, parasitic component measurement of printed circuit boards, and dielectric property evaluation of electronic materials. Includes products with frequency characteristic measurement functions, automatic measurement functions, and data logger functions, positioned as dedicated precision measurement instruments distinct from oscilloscopes and multimeters.
