Step-by-Step Assembly:

Adjusting Focus Tension:
If it becomes hard to move the coarse focus knob, or
the stage drifts and the sample falls out of focus the
tension needs to be adjusted.
Tighten the tension by adjusting the tension
adjustment ring (1) in the direction of the arrow
shown at right.
Loosen the tension by rotating the tension
adjustment ring in the opposite direction.
Diopter Adjustment:
Align the scale to “0” on the diopter adjustment ring
(1) with the scale (2).
Focus the microscope to a clear image while looking
through one eyepiece only.
Look through the other eyepiece and rotate the
diopter adjustment ring on that eyepiece until the
image is clear.
If multiple people are using the microscope, note
your diopter setting for quick transition from users.
Interpupillary Distance Adjustment:
When observing with both eyes, adjust the
eyepieces (2) to fit your personal interpupillary
distance.
The scale between the eyepieces (1) notes the
interpupillary distance setting.
Centering the Condenser:
Rotate the condenser height knob (1) to raise the
condneser up to the highest position.
Rotate the 10x objective into position and focus.
Rotate the field iris diaphragm adjustment ring (2) so
the field is in the smallest position.
Rotate the condenser height knob (1) so the image is
crisp and clear.
Adjust the condenser centering screws (3) so the
image is in the center of the field of view.
Open the field iris diaphragm (2) slowly. If the image
remains in the center, the condenser has been
centered properly.
