UNPACKING, ASSEMBLY, PREPARATION FOR USE
UNPACKING
All MEIJI TECHNO Microscopes are usually supplied in an expanded polystyrene, 2-part case and this
should be used for storage, possible transport in the future, etc. If your order includes a wooden
storage cabinet, release the fixing screws holding the limb and base from the cabinet and withdraw.
Unpack the microscope and its parts carefully. Do not throw away any boxes or packing materials until
contents of the shipping container have been checked against your order and the packing list sent.
ASSEMBLY
To mount the vertical illuminator (packed separately), loosen the clamp screw and insert the cone
fitting of the illuminator into the recess on the top of the limb and push the cone fitting toward and
against the spring stopper
clamp screw
Now, the binocular or trinocular body can be mounted on the vertical illuminator.

Spring stopper
Place the microscope and parts on a sturdy table or desk which gives firm and stable support. This
should be located in the atmosphere as clean as possible, avoiding the places where there is excessive
dust, moisture, heat or fumes.
When in place insert eyepieces in the eyetubes of the binocular body and mount the objectives on the
objective nosepiece, starting with the lowest magnification, then positioning the others to the right of the
next lowest magnification objective.

OPERATING INSTRUCTIONS
OPTICAL SET-UP AND BRIGHTFIELD ILLUMINATION
After connecting the illuminator plug to the receptacle at the back of the microscope base, please
follow as indicated below:
[1] Turn on the illuminator. Place the specimen slide you wish to examine on the microscope stage
and rotate the nosepiece to bring the 10X objective into position for focus.
[2] Make sure that both the field iris
(a) and the aperture iris (b) are fully
open.
[3] Slide the Illumination Selector to the central position where the middle Empty Hole comes
across the Light Axis. This is the Brightfield Illumination.

[4] Pull the Analyzer Slide out to the full so the Analyzer gets out of the light path.
[5] Focus down on your specimen slide until surface detail can be seen. Adjust the brightness of the
built-in light source, using the intensity control knob, left-hand back on the base.
[6] BINOCULAR ADJUSTMENT
Comment: Using a binocular body is much more efficient and less tiring than monocular bodies, but it
must be adjusted correctly. When it is perfectly adjusted the images coming from the two eyepieces are
“fused” into one better image in eyes of the observer.
