Fig. 14
*If
the
easily recognizable point A disappears from the field of view
entirely when the stage is rotated 18W, the stage is significantly off-
center. Proceed
as follows: Visualize
the imagined center E of the circle
that point A appears
b
be traveling as the stage
I s
rotated. Udng the
atage canbring screws, move
this imagined center
E
toward the
intersection
off
he crass hairs. Rotate
the
stage completely again to see
if p i n t A stays in the field of view for theentire rotation. If
not, repeat
this
procedure
urlng
the stage centering
screws
until point A (or any other
easily
recognizable
point) stays in the field
of view
for a complete
rotation
(diagram
a'and b'). Then proceed as in 2,3 and 4,
above.

F. Centering the
Objecthe8
The centration of the objectives is needed for all the PO objectives
except the PO
10X objective. The
IOX objective is mounted
on
the
nosepiece in the opening which
does
not have centering wrench
screws
immediately to the left and right of the 10X objective.
1. After
completing centration
of
the stage as described above with use
of the lOX objective, the centering wrenches must be inserted into the
nosepiece
on
both sides of the objective to be centered. Rotate the
nosepiece
to
bring
this objective directly over the specimen being
viewed.
2. Use a procedure similar to step 2 and
3
and 4
above. The
centration
now is
accomplished by using the nosepiece centering wrenches, El
NOT the stage
centelng
knobs,
to
cause a specimen to
m
in a
drcte with the eyepiece cross hairs being the center of that circle. See
diagrams a,
b, c
abwe,
3.
This centration
procedure must be repeated foreaeh individual objec-
five (other than the 1 OX) on the nosepiece wlthwt using
the
stage
cenwrlng knobs.
4. Test the centration
of the objective by observing a recognizable point
in the specimen, e.g., near 6o'clock position,
and rotating the stage to
complete the circle. The specimen should move to 9 o'clock,
12
o'clock, 3 o'clock, and back to 6 o'clock if the centration
is
accurate
(See dlkgrams d and e below).
