Introduction
This
chapter
describes
how
to
measure
the
dielectric
constant
(")
of
the
liquid
using
the
16452A.
The
standard
measurement
sequence
is
shown
in
this
chapter
.
Some
instructions
for
the
temperature
measurement
are
provided
at
the
back
of
the
chapter
.
Measurement
Sequence
Relative
permittivity
("
r
)
can
be
calculated
from
the
ratio
of
the
capacitance
of
a
material
to
that
of
air
(nearly
equal
to
that
of
a
vacuum).
The
standard
measurement
sequence
is
as
follows:
1.
Prepare
the
test
xture
for
use
.
2.
Connect
the
test
xture
.
3.
Check
the
SHORT
residual.
4.
Set
the
instrument
for
capacitance
measurement.
5.
Do
a
SHORT
compensation.
6.
Do
the
air
capacitance
(C
0
)
measurement.
7.
Do
the
liquid
capacitance
and
resistance
(Cp
,
Rp)
measurement.
8.
Drain
the
liquid
(after
measurement).
9.
Do
the
data
processing|Calculate
dielectric
parameter
from
measurement
data.
Measurement
Requirements
T
o
do
the
measurement,
the
following
items
are
required:

for
the
SHORT
compensation
(furnished
with
the
16452A)
Shorting
plate
for
the
SHORT
compensation
(furnished
with
the
16452A)
A
spacer
(choose
one
of
the
furnished
four
spacers)
Measurement
instrument
(
4194A,
4284A,
or
4285A)
Liquid
under
test
(enough
for
the
spacer
you
are
using)
In
addition,
the
following
items
are
useful:
F
or
washing
the
16452A,
a
brush,
detergent,
cloth,
etc
.
F
or
high
temperature
measurements
,
gloves
to
prevent
scalding.
