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
the contents of the shipping container have been checked against your order and the packing list sent.
ASSEMBLY
REFLECTED LIGHT ILLUMINATOR, unpacked from the separate case, goes onto the microscope limb
in the following way:
(1)Loosen the Clamp Screw
(2)The male cone-fitting of Vertical Illuminator is mounted into the femal cone-fitting at the limb top
so the Clamp Screw

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
centering objective nosepiece, starting with the lowest magnification, but positioning the 10X in the fixed
(not centerable) opening. Then position the others to the right in order of increasing magnification.
A focusable cross-line eyepiece should be used in the slotted eyetube. Make sure that it is
into the slot in the eyetube, as its orientation is important and should not change. The cross-line should
be sharply focused by turning the focusing ring.

IMPORTANT!
Before plugging the illuminator into any electric outlet, make sure that transformers and illumination
bases supplied to you are suitable to the current available (See voltage indication at the bottom of limb).
OPERATING INSTRUCTIONS
OPTICAL SET-UP AND TRANSMITTED LIGHT ILLUMINATION
(1)Turn on the Transmitted Light Illuminator by turning the Switch . Place the specimen slide you wish
to examine on the microscope stage and rotate the 10X objective into position for focus.
(2) Move the substage condenser up to its top position, using the rack and pinion focusing control
Check to make sure that both the field iris

and the aperture iris are fully open.

Switch and light
intensity control
(3) Focus down on your specimen slide until detail can be seen. Adjust the brightness of the in-base
light source, using the intensity control knob
BINOCULAR ADJUSTMENT
Comment: Using a binocular body is much more efficient and less tiring than a monocular body, 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.
