The fine focusing knob is attached on the right side as a
factory default.
The fine focusing knob is a detachable type in order to
prevent the interference between the fine focusing knob and
your hands while operating the X-axis knob or the Y-axis knob.
Normally, attach the fine focusing knob on the opposite side
of the X-axis knob or the Y-axis knob.
Loosen the clamping screw
a
with the Allen screwdriver to remove
the fine focusing knob
b
.
Remove the screw hole sticker of the fine adjustment dial on the
opposite side, and attach the fine focusing knob
b
in the reverse
procedure of removing.
Attach the provided sticker to the screw hole of the fine adjustment dial
of the side where the fine focusing knob
b
was removed.
The fine adjustment dial
c
is used for the fine operation with
the finger tip or ball of a finger.

TIP
Be sure to use the tension adjustment ring
a
for
adjusting the tension of the coarse focusing knob.
The tension of the coarse focusing knob is adjusted to the easy-
to-use tension, but if you want to change the tension, turn the
tension adjustment ring
a
in the arrow direction to increase the
tension and turn in the opposite direction to decrease the tension.
If the stage descends by its own weight or the focus obtained with
the fine focusing knob is lost soon, the tension is set too loose. In
this case, turn the tension adjustment ring
a
in the arrow direction
to increase the tension.
NOTE
Turn the coarse focusing knob
a
and the fine focusing knob
b
in
the arrow direction to move the stage upward. (The sample approaches
the objective.)
