Adjusting the Diopter
Using the Eye Guards
When Wearing Eyeglasses
Use with the eye guards in the normal, folded-down position. This will
prevent the eyeglasses from being scratched.
When Not Wearing Eyeglasses
Extend the folded eye guards outwards (direction of the arrow) to
prevent ambient light from entering into your line of vision.

Procedure for adjusting the diopter:
1. Rotate the right eyepiece to match the markings of your IPD (If your
IPD is 64, rotate the eyepiece to 64 mark).
2. While looking through the right eyepiece with your right eye, rotate
the coarse and fine adjustment knobs to bring the specimen into
focus.
3. While looking through the left eyepiece with your left eye, rotate only
diopter adjustment ring on the eyepiece until specimen is at its best
possible focus.
The condenser is most often used in the highest position. If the observed
field of view is not bright enough, brightness may be improved by lowering
the condenser slightly
1.
Rotate the condenser height adjustment knob (2) to move the
condenser to the highest or desired position.
2.
The aperture iris diaphragm ring (1) has an objective magnification
scale. Slide the diaphragm lever left right to achieve the desired
illumination level.
3.
Swing in the flip top condenser on 40x and 100x magnification. The
flip top condenser should be in swing out position on 4x and 10x
