This diagram shows the parts and order for installing SZ series stereo microscopes. Make sure the surface of the unit
is clean before installation.
4 Operation
4-1 Adjust the diopter
(1) Maximize the magnification power by turning the zoom control knob.
(2) Turn the diopter adjustment ring to “0” position.
(3) Look through the right eyepiece, and make the image clear by turning the
focusing knobs.
(4) Turn the zoom control knob to the minimum magnification.
(5) Look through the right eyepiece again. If the specimen goes out of focus,
readjust the focus by turning the right diopter adjustment ring only.
(6) Do the step(1) and look through the right eyepiece. If the image is not clear,
Re-do the step (3)~(5) and make the adjustment more precise.
(7) Do the step (4) and look through the left eyepiece and make the image clear
by turning the left diopter adjustment ring.
4-2 Adjust the interpupillary Distance
(1) Hold the right and left eyepiece tubes, and turn the tubs in the
direction of the ARROWS until the observation is comfortable.
4-3 Mount the C-mount video Adapter and Video camera

Monitor, make the image clear by turning the focusing knob.
(3) Turn the zoom control knob to the minimum magnification. Adjust the focusing
ring ② to get the clear image.
