Measuring Resistivity
of Insulation
Materials
This
section
provides
measurement
example
of
resistivity
of
insulation
lm
using
the
16008B
Resistivity
Cell
with
the

50
main
electrode
.
Warning
Do
NOT
touch the
UNKNOWN
terminals or
the electrodes
of
the
accessory
,
when
the High
Voltage
indicator is
ON, the
4339B
outputs
dangerous
voltage
levels up
to 1000
Vdc. Before
handling the
4339B
or
the
accessory
,turn
OFF the
test voltage
pressing
and
conrm that
the
High
Voltage
indicator is
OFF
.
Note
The
thickness
of
the
DUT
should
be
measured
accurately
because
thickness
data
is
used
to
calculate
volume
resistivity
.

T
o
reduce
the
reading
error
when
you
measure a
thickness
using
a
micrometer
,
you
should
average
the
thickness
values
measured
at
several
points
in
the
measurement
area
and
then
use
this
average
value
to
obtain
the
dielectric
constant.
1.
Connect
the
shunt
connector and
the 16008B
to the
4339B as
shown
below
.

Press
to display the reset
menu. Select
Yes using
or and press .
3. Set the source voltage value.
Press . Enter the voltage value, for example 500 (V), and press .
