Stage with Rotating Mechanism

6.1
Loosen the rotation clamp screw on the bottom
surface of the stage to allow the stage to swivel.

Centering the Stage

6.2
(1) Move the 10x objective into the optical path
and focus on the specimen. Select a specific
point on the specimen as a reference point,
then move the reference point to the center
of the field of view using the stage knobs.
(2) Loosen the stage rotation clamp screw and
rotate the stage approximately 180°.
(3) If the reference point deviates from the center of the field of view, insert the hexagonal
screwdriver into the stage-centering screws* (2 locations) and adjust by moving the stage
a distance equal to the distance traveled by the reference point from the center of the field
of view.
(4) Using the stage knobs, return the reference point to the center of the field of view.
(5) Move the 40x objective into the optical path and repeat steps 2 through 4.
* The stage-centering screws (also used as mounting screws) are located at two points on
the back of the elevating section.

Selection of Magnification

7
To change magnification, turn the revolving
nosepiece and set the desired objective into the
optical path.
If the DIH-M is mounted to the microscope, the
zoom knob on the right side allows adjustment of
magnification between 0.8x and 2x.
Clockwise rotation of the zoom knob increases
magnification. The number at the pointer indicates
the effective magnification. The knob clicks at each
0.2x increment.
Total magnification is calculated as follows:
Magnification of eyepiece lens x Magnification of objective x Magnification of zoom knob
