Signal
Noise

been
Rejected
Notes:
The
use
of
average
sampling
makes
waveform
display
and
update
slower,
as
well
as
having
no
persistence
effect,
which
is
a
normal
phenomenon.
High

Random
Noise
Average
mode
has
certain
defects:
the
use
of
average
sampling
makes
waveform
display
and
update
slower,
as
well
as
having
no
persistence
effect,
which
is
inconvenient
for
operation
under
certain
circumstance.
However,
high
resolution
well
overcomes
this
issue.
Average
modes
used
by
“average”
and
“high
resolution”
modes
are
not
the
same,
with
former
being
the
“average
based
on
multiple
samplings”
and
the
latter
being
the
“average
based
on
a
single
sampling”.
Specific
operations
are:
Press
ACQUIRE
key
located
on
the
menu
area
of
the
panel
to
display
sampling
setting
menu.
Press
F1
key
and
then
press
“MULTIPURPOSE”
knob
to
set
sampling
mode
as
“high
resolution”
and
then
“SELECT”
to
confirm.
