Dielectric loss and dielectric constant are all kinds of porcelain, porcelain, ceramic capacitor device, and composite materials is an important physical properties, by measuring the dielectric loss tangent of dielectric constant （ Tan δ andε）, to further understand the effects of dielectric loss and dielectric constant of the various factors, in order to improve the material the property basis; instrument basic principle is the use of high frequency resonance method, and provides, universal, multi-purpose, multiple range impedance test. It uses single-chip computer as the control core of measuring instrument, using the frequency locking, frequency standard test point automatic setting, resonant point automatic search, Q value range automatic conversion, numerical display and other new technology, improved the tuning circuit, the tuning circuit for testing the residual inductance is reduced to the minimum, and retains the original Q table in the automatic amplitude stabilizer technology, makes the new instrument in the use of more convenient, measurement is more accurate. Instrument in high frequency test conditions, measurement of high frequency inductive or resonant loop of the Q value, the inductance of the inductor is the amount and distribution of capacitance, capacitance and loss angle tangent value of electrical materials, dielectric loss in high frequency, high frequency circuit in parallel and series resistance, the characteristic impedance of the transmission line and so on.
