The dielectric constant and dielectric loss tester tester

Meet the standards: GBT 1409-2006 measurement of electrical insulating materials at power, audio, high-frequency (including wavelength, VHF)recommended methods of permittivity and dielectric loss factor

One, overview

The dielectric loss and dielectric constant is all kinds of porcelain,porcelain, ceramic capacitors and other devices, and composite materialsis an important physical properties, by measuring the dielectric loss tangentof Tan δ and Permittivity (epsilon), can further understand the factors influencing the dielectric loss and dielectric constant, and provide the basis for improve the properties of materials; the basic principle of instrument is using high frequency resonance method, and provides a general, impedance test, multi use, multi range. It uses single-chip computer as core control 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, more accurate measurement. Instrument in high frequency test conditions, measurement of high frequency inductor and resonant loop of the Q value, inductance and distributed capacitance of inductors, capacitance and loss tangent of dielectric loss, high frequency electrical materials, high frequency circuit in parallel and series resistance, the characteristic impedance of the transmission line
