1.Description:
Dielectric loss and dielectric constant are important physical
properties of various ceramics such as electrical porcelain, device
porcelain, capacitors, and composite materials, etc. By measuring
the dielectric loss tangent (tanδ) and dielectric constant (ε), one
can further understand various factors affecting dielectric loss
and dielectric constant, providing a basis for improving the
performance of materials. The basic principle of the instrument is
to adopt the high-frequency resonant method, and it provides a
universal, multi-purpose, and multi-range impedance testing. It
uses a single-chip computer as the instrument's control, with
automatic conversion of Q value range, numerical display, and other
new technologies. It improves the tuning circuit, reducing the
residual inductance of the tuning test circuit to the minimum, and
retains the automatic amplitude stabilization technology in the
original Q meter, making the new instrument more convenient to use
and the measurement values more accurate. The instrument can
measure the Q value of high-frequency inductors or resonant
circuits, the inductance and distributed capacitance of inductors,
the capacitance and dielectric loss tangent value of capacitors,
the high-frequency dielectric loss of electrical materials, the
effective parallel and series resistances of high-frequency
circuits, and the characteristic impedance of transmission lines
under higher testing frequency conditions. This instrument is used
by research institutions, schools, factories and other units for
the application research on the performance of inorganic
non-metallic new materials.
