Introduction: Dielectric loss and dielectric constant are an important physical property of various electric ceramics, device ceramics, capacitors and other ceramics, as well as composite materials. By measuring dielectric loss tangent tanδ and dielectric constant (ε), we can further understand the influence of Various factors of dielectric loss and dielectric constant provide a basis for improving the performance of materials; the basic principle of the instrument is to use the high-frequency resonance method, and provides a general, multi-purpose, multi-range impedance test. It uses a single-chip computer as the control of the instrument, and the measurement core adopts new technologies such as frequency digital locking, automatic setting of standard frequency test points, automatic search for resonance points, automatic conversion of Q value range, and numerical display. The residual inductance of the test loop is minimized, and the technology of automatic amplitude stabilization in the original Q meter is retained, which makes the new instrument more convenient to use and the measurement value is more accurate.
