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

The binocular or trinocular body which is stored separately should now be mounted on the limb and
clamped, when it is squared with the base.

It is important that the body be oriented correctly on the microscope limb. Make sure, therefore, that
the point of the Clamp screw

gets fit to the Slot milled on the bottom face of the body.

Cone fitting

[Adverse side of body]

To mount the body, loosen the Clamp screw and insert the Cone fitting of the body into the recess
in the top of the limb and clamp it by the clamp screw.

Place the microscope and parts on a sturdy table or desk which gives firm and stable support. This
should be located where the atmosphere is 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 ILLUMINATION

(1) Turn on the illuminator. 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

(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

and the Aperture iris are fully open.

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.
