TRIGGER
MODES
There
are
four
trigger
modes:
rising
slope
falling
slope
engine
i nternal
When
rising
slope is
selected,
the
scope will
start writing
the waveform
when
the
voltage
of
the
signal increases.
When
falling
slope is
selected, the
scope
will
start writ'ing
the waveform
when
the voltage
of
the
signal
decreases.
With
the
engine trigger
selected,
the
scope
will
start
to write
the waveform
when
the tester
receives
a
signal
from
the
first
cylinder
(red
clamp).
The
internal
trigger
will write
a
signal continuously
on
the
screen. You
can
step up through
the
trigger
modes
w'ith
the 7
key
and step
down with
the
I
key.
TRIGGER
LEVEL
For
the rising
slope
and the falling
slope
you
can
set
a
trigger
level,
this
determines
at wh'ich
voltage
the
waveform
will
start. There
are 4
trigger
levels
:
0,5V
3V
10v
20v
You
can
step
up through
the
trigger
level
with
the
>
key
and
step
down
with
the
+/-
key.
