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.
