Release
the
shutter
at
a
speed
of
1/4,
and
make
adjustment
by
means
of
Rip
(resistance
for
long
split-second
timing
adjustment)
so
that
the
measured
value
may
approach
the
standard
(250ms).
Rip
loses
speed
when
turne
left
and
gains
speed
if
turned
right.
(Refer
to
the
figure below).
After
1/4
adjustment,
release
the
shutter
at
a
speed
of
1/1000,
make
adjustment
by
means
of
Riz
(resistance
for
short
split-second
timing
adjustment)
so
that
the
measured
value
may
approach
the
standard
(0.98ms).
Riz
gains
speed
if
turned
left
and
loses
speed
if
turned
right.
(Refer to the figure below).
Mi When manual split-second timing is
“OPENING” or “QUICK SHOOTING”,
for cause of trouble refer to the
chart (P. 3)
Wlf printed base plate A is replaced,
make adjustment after each of variable
resistances (Ri, Rz, R3-::) has been
set approximately in the center.
