How
to
Reduce
the
Measurement
Error
The
measurement
error
due
to
the
DC
voltage
source's
noise
can be
reduced by
connecting a
resistor
in
series
with
the
DUT(capacitor).
Figure
6-6
shows
the
DC
resistance
and capacitance
value that
can be
measured within
10%
additional
error
when
connecting
a
series
resistor (1
k, 5
k, 10
k, 50
k, and
100 k).
The
external
DC
voltage
source
used
in
this
example
is
the
same as
that of
Figure 6-5
.
F
or
example
,
in
the
case of
measuring a
10 
F capacitor's
resistance
,
the
maximum
resistance
that
can
be
measured
within
10%
error is
-
about
200
M
without
a
series resistor
,
-
about
1.8
G
with
a
100 k
series resistor
.
As
shown
in
Figure
6-6,
the additional
error due
to
the
DC
voltage
source's
noise
can
be
reduced
by
connecting a
series resistor
,plus
you
can
expand
the
measurable
resistance/capacitance
range
.
However
,it
must be
noted that
the
required
charging
time
for
the
DUT
becomes
longer
if
you
connect a
series resistor
.
