3. Preparing for Inspection
1) Set the main switch “A” to “I” (ON).
2) Adjust the brightness by turning the adjustment knob “B” .
3) Place a specimen on the stage.
4) Engage the 10X objective in the light path.
5) Rotate the condenser height adjustment knob ”C” to move the condenser to the highest position.
* The condenser is usually used in the highest position. If the entire observed field of view is
not bright enough, brightness may be improved by lowering the condenser slightly.
6) Looking through the eyepiece in the right sleeve without the diopter adjustment ring, turn the
coarse and fine focus adjustment knobs “D” to bring the specimen into focus.
7) Looking through the eyepiece in the left sleeve with the diopter adjustment ring, turn only the
diopter adjustment ring “E” to focus on the specimen.
(At this time, adjust the interpupillary distance so that the binocular visions on the left and right
fields of view coincide completely.)
8) Adjust the aperture iris diaphragm;
Since the aperture irirs diaphragm has an objective magnification scale (4X, 10X, 40X,100X),
rotate the diaphragm ring “F” so that the magnification scale corresponding to the objective
in use faces frontward.
