4284A
The
4284A
uses
two
kinds
of
OPEN/SHORT
correction
data
as
follows
.
1.
The
OPEN/SHORT
correction
data
which
is
taken
at
all
preset
frequency
points
independent
of
the
test
frequency
you
set,
and
the
OPEN/SHORT
correction
data
for
each
measurement
point
over
the
specied
frequency
points
is
calculated
using
the
interpolation
method.
2.
The
OPEN/SHORT
correction
data
which
is
taken
at
the
frequency
points
you
specify
allows
you
to
set
up
to
three
frequency
points
in
the
FREQ1,
FREQ2,
and
FREQ3
elds
.
P
erform
the
following
steps
to
execute
the
OPEN/SHORT
correction
at
all
frequency
points
using
the
interpolation
method.
1.
Connect
the
attachment
with
the
cover
to
the
Guarded/Guard
electrode
.
2.
Press
4
MEAS
SETUP
5
and
move
the
cursor
to
the
OPEN
eld.
3.
Press
NNNNNNNNNNNNNNNNNNNNNNNNNNNNN
MEAS
OPEN
to
start
measuring
the
OPEN
admittance
(capacitance
and
inductance)
at
the
preset
frequency
points
.
The
time
required
to
measure
the
OPEN
correction
data
is
approximately
90
seconds
.
During
the
OPEN
correction
measurement,
N
NNNNNNNNNNNNNNNN
ABORT
is
available
to
stop
the
OPEN
correction
data
measurement.
The
previous
OPEN
correction
data
will
still
be
stored.
4.
Press
NNNNNNNNNNNNNNNNNNNNNNN
OPEN
ON
to
perform
the
OPEN
correction
calculations
on
subsequent
measurements
using
the
OPEN
interpolation
correction
data
when
the
FREQ1 ,
FREQ2
and
FREQ3
elds
are
set
to
OFF .
When
the
FREQ1 ,FREQ2
and
FREQ3
elds
are
set
to
ON ,
and
the
test
frequency
is
equal
to
FREQ1/2/3,
the
OPEN
correction
data
at
FREQ1/2/3
is
used.
5.
Remove
the
attachment
from
the
electrode
.
6.
Connect
the
attachment
without
the
cover
to
the
Unguarded
electrode
of
the
16451B
.
7.
Move
the
cursor
to
SHORT
eld.
(If
there
is
no
SHORT
eld
in
the
display
,
press
4
MEAS
SETUP
5 ,
NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN
CORRECTION
,
then
the
SHORT
eld
will
be
displayed.)
8.
Press
NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN
MEAS
SHORT
to
measure
the
SHORT
impedance
(inductance
and
resistance)
at
the
preset
frequency
points
.
The
time
required
to
measure
the
SHORT
correction
data
is
approximately
90
seconds
.
During
the
SHORT
correction
measurement,
NNNNNNNNNNNNNNNNN
ABORT
is
available
to
stop
the
SHORT
correction
data
measurement.
The
previous
SHORT
correction
data
will
still
be
stored.
9.
Press
NNNNNNNNNNNNNNNNNNNNNNNNNN
SHORT
ON
to
perform
the
SHORT
correction
calculations
on
subsequent
measurements
using
the
SHORT
interpolation
correction
data
when
the
FREQ1 ,
FREQ2
and
FREQ3
elds
are
set
to
OFF .
When
the
FREQ1 ,FREQ2
and
FREQ3
elds
are
set
to
ON ,
