If
Y

Have
A
Problem
When
Y
ou
Make
A
Measurement
If
Y
ou
Get
Unexpected
Data
when
P
erforming
Sam-
pling
Measurement
If
initial
interval
is
set
to
a
short
time
and
if
FIL
TER
ON
is
set,
you
may
get
unwanted
data.
FIL
TER
ON
causes
a
slower
rise
time
,
so
short
initial
interval
will
sample
during
this
rise
time
.
T
o
solve
this
problem:
Set
FIL
TER
eld
to
OFF
if
you
set
initial
interval
to
a
short
time
.
Some
data
may
be
skipped
because
measurement
takes
a
long
time
.
Measurement
takes
a
long
time
if
measurement
is
performed
in
a
low
current
range
,
if
many
measurement
channels
are
set
up
,
or
if
analysis
,
such
as
moving
a
marker
,
is
performed
during
measurements
.
T
o
solve
this
problem:
Measure
current
using
a
xed
range
that
is
more
than
10
A.
F
or
measurement
ranges
10
A
or
less
,
measurement
takes
longer
than
the
specied
integration
time
.
Decrease
measurement
channels
to
reduce
measurement
time
.
Note
that
the
number
of
measurement
channels
automatically
increases
if
you
do
both
the
following:
force
voltage
from
channels
that
are
connected
to
R-Box
and
display
the
voltage
values
or
use
voltage
values
in
user
functions
.
The
channels
automatically
measure
current,
which
is
used
to
compensate
the
voltage
values
.
Do
not
perform
analysis
operation
during
measurement
state
