Measure
simple
signals
Observe
unknown
signal
of
a
circuit
and
measure
and
display
the
frequency
and
amplitude
of
that
signal
rapidly.

．
To
display
the
signal
rapidly,
please
follow
the
following
steps:
①、
Set
the
probe
attenuation
coefficient
to
be
10
×
,
and
set
the
switch
on
the
probe
to
be
10
×
.
②、
Connect
probe
of
CH1
to
the
measuring
point
of
the
circuit.
③、
Press
AUTO
key.
The
oscilloscope
will
run
auto
setup
to
achieve
best
effect
of
waveform
displaying.
On
this
basis,
users
can
further
adjust
the
vertical
and
horizontal
scale
till
the
display
of
a
waveform
satisfies
your
requirements.

Voltage
and
time
parameters
for
auto
measuring
of
signals
Oscilloscopes
can
measure
most
of
the
displaying
signals
automatically.
To
measure
peak
‐
peak
value
and
frequency
of
a
signal,
please
follow
the
following
steps:
①、
Press
MEASURE
key
so
as
to
display
auto
measuring
menu;
②、
Press
F2
key
to
select
measuring
menu;
③、
Use
“MULTIPURPOSE”
knob
to
select
peak
‐
peak
value,
press
the
same
to
confirm
and
then
choose
frequency;
④、
Press
F5
key
to
exit
select
box.
Right
now,
measurement
result
of
peak
‐
peak
value
and
frequency
are
displayed
at
the
lower
part
of
the
screen
respectively,
as
shown
below.

Capture
a
Single
Time
Signal
The
advantages
and
features
of
digital
oscilloscope
lie
in
that
it
can
capture
non
‐
cycle
signal
conveniently,
including
pulse
and
burr.
To
capture
a
single
time
signal,
first
of
all,
users
must
have
certain
prior
knowledge
on
that
kind
of
signal
so
that
they
can
set
the
trigger
level
and
trigger
edge
accordingly.
For
example,
if
the
pulse
in
question
is
a
logic
signal
of
TTL
level,
then
the
trigger
level
should
be
set
to
2
volts
approximately
and
the
trigger
edge
should
be
set
to
rising
edge
trigger.
If
users
are
uncertain
about
the
condition
of
the
signal,
they
are
suggested
to
observe
the
signal
first
through
auto
or
common
trigger
method
so
as
to
confirm
the
trigger
level
and
trigger
edge.
