(By moving Test Plate
KN0003,
the center
of
the concentric
circles
positioned
with
the
zoom magnification set
at
1 X
·
is
made
to

b)
Insert
C-2
into
the right
mirror
unit
and
set
the zoom magnification at 1 X. Move Test
Plate
KN0003
to
make the center
of
its
con-
centric
circles
coincide
with
that
of
the
cross
hair
of
C-2.
Change
the zoom magnification
to
4X
and
the center
of
the concentric
circles
will
move.
Then, move the
Test
Plate
again
to
the
1
X position.
Put
the zoom
mag-
nification back
to
1
X
and
the center
of
the
concentric
circles
will
move again. With the
position
of
the center
of
the concentric
circles
kept
in mind, change the zoom
magnification
again'
to
4X
and
the center
will
shift
once again. Then, move the Test
Plate
to
shift
the center
of
the concentric
circles
to
the spot
that
is
memorized
as
where the center
was
when the zoom
mag-
nification
was
set at
1X.
Repeat the above
steps
of
moving the Test Plate
and
changing
the zoom magnifications and the center
positioned
with
the zoom magnification
set
at 1X
will
finally
coincide
with
that
posi-
tioned
with
the zoom magnification being at
4X.
In
this
case,
the center
of
the concentric
circles does
not
have
to
always
coincide
with
that
of
the
cross
hair.

Fig. 62.)

CAUTION:
Under no circumstances must the Test
Plate
be
manipulated
once the
two
centers
of
the
concentric
circles
have
coincided
with
each
other.
c)
Make the center
of
the
cross
hair
of
C-2
coincide
with
that
of
the concentric
circles
of
1 X and
4X
magnifications.
Apply
Alien
wrenches OT 0205
to
the
3 screws,
two
ACU4x8SA
and one
ACU4
x6SA,
both
of
which
are
referred
to
in
a)
above
and
make the center
of
the concentric
circles
of
1 X
and
4X
magnifications coincide
with
that
of
the
cross
hair
by
moving the
screws back
and
forth.
