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 into the cabinet and withdraw.
Unpack the microscope and its parts carefully. Do not discard any boxes or packing materials until the
contents of the shipping container have been checked against the packing list sent and your order.
If an EMZ Zoom stereo microscope has been shipped, base, limb and zoom stereo body will be
shipped together as a unit. Remove from the styrofoam back, holding the base in one hand and
supporting the zoom stereo body with the other.
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 places where there is
excessive dust, moisture, heat or fumes.
ASSEMBLY
When in place, insert eyepieces in the eyetubes of the binocular body. Zoom stereo body are already
in place on the limb, as shipped. Cover with the plastic dust cover supplied until ready for adjustment
and use.
If you ordered zoom stereo body and stand separately, loosen the set screw and insert the zoom body
into the holder then tighten the set screw after setting at the desired position.
IMPORTANT!
Before plugging the illuminator into any electric outlet, make sure that transfomers and illumination bases
supplied to you are suitable to the current available. (When shipped, these will be labelled as to mains
voltage and cycles specification.)

FOCUSING CAPABILITY
The Pole-type focusing stands have a double focusing capability, i.e.
Rough Focus (by sliding the whole focus assembly and zoom
body up and down on the pillar, fixing the clamp screw when in
approximate focus on your specimen), Precise Focus (by using
the rack and pinion focusing knob).
The focusing stands, P, PL, PX, PC, PB, PBH and BX are the Pole-
type.

Before moving the whole focus assembly up and down for rough focus, loosen
pillar collar once and make sure to reset after the rough focusing is done.
How to use selector switch and dimmer switch
Focusing stands, PBH, ABZH and ABE, are using 6V 10W Halogen lamps with suitable transformers built-
in base and a selector switch and a dimmer switch on the base.
Select an illuminator to use, either incident or transmitted, by the selector switch in the way described
above. Then, turn the dimmer switch knob slowly to clockwise to turn the dimmer switch ON and to increase
brightness. Turn the knob to counterclockwise to decrease the brightness and to turn OFF.

FOCUSING PROCEDURE
The whole point of stereoscopic microscopes is that, when properly adjusted, the observer sees the object
image in three dimensions and can perceive height and depths on the specimen. This is a great advantage
in material examination and quality control techniques.
To achieve these desirable height/depth effects the images coming from the binocular eyepieces must be
"fused" into a single image by the observer - this requires some practice and careful setting of the binocular
body. Procedure is as follows:-
The operator should move eyepiece tubes in and out to find the place where the distance between
eyepiece centers matches the distance between the pupils of his own eyes. This is the interpupillary
distance and will vary somewhat from operator to operator. When these distances are equal (or match),
one central image is seen by the operator.
54-74mm
"Fused"
When replacing stage plate loosen the set screw
which is visible infront of the stage.

The Rigid arm type focusing stands (except the
model ABE) have a focusing capability only by
rack and pinion adjustment. This means that the
available range of specimen sizes/depths which
can be accommodated is somewhat less than in
the case of Pole-type stands.
The Rigid arm type ABE focusing stand is with
integral focus block and extendable working
distance. Provides transmitted and incident
halogen illumination.
To extend working distance,
loosen the clamp screw and
extend the arm upward and
set the screw back.
AZ, ABZ and ABZH

focusing stands.

PRECISE FOCUS ON SPECIMEN
Stage Plates
You should now decide which of the stage plates supplied will be most suitable.
The focusing stands with plain bases, P, PL, PX, PC and A, are supplied with reversible black and white
stage plates. Your selection depends on which side, black or white, gives the best contrast conditions with
your selected specimen.
The focusing stands with transmitted illuminators, PB, PBH, ABZ, ABZH and ABE, are supplied with clear
glass stage plates and reversible black and white stage plates. If the specimen is semi-transparent, the
glass stage plate shoud be used with transmitted illumination switched on. If the specimen is opaque, use
the black/white stage. Your selection depends on which side,
black and white, gives the best contrast.

Finally it is necessary to adjust, so focus remains sharp through the whole range of zoom magnification
and so that the image is seen equally sharply focused in both right and left-hand eyepieces.

Set microscope magnification to the highest power 4.5X by turning the zoom control knob counter-
clockwise.
Then focus sharply on the specimen.
Set to the lowest magnification by turning the zoom control knob clockwise. Do not touch the focusing
controls.
Looking with the right eye through the right-hand eyepiece, turn the eyepiece’s dioper adjustment ring
until the image is precisely in focus.
Do the same with the left eye and left-hand eyepiece.
The fused microscope image should now be uniformly sharp throughout the zoom range and without
refocusing.

PHOTOGRAPHY
Photographic documentation of microscope visual images is most conveniently achieved by using the
trinocular (photo-binocular) bodies offered for use with MEIJI TECHNO microscpoes.
In the case of the EMZ-TR Zoom Stereo series a trinocular is supplied with lever-switching of the
image from one of the binocular eyepieces vertically up to the film plane of a 35mm SLR camera with
adaptor mounted on the vertical photo tube. Visual observation can be simultaneously carried out,
using the other eyepiece.
In this system the MA150/50 and MA150/60 Camera Attachment should be used with the SLR camera
model of your choice. Please note that one of the large range of T2 Adaptor Rings suiting to your
camara should have been ordered and supplied.
These adaptor rings are intended to compensate for the small differences in effective distance of the
film plane in your camara - so as to ensure that photographs are optimally sharp, and achieved without
wastage of film in trial shots and experimentation.
In addition special low-power camara eyepieces (2.5X, 3.3X and 5X) are available and recommended
- these will give you maximum field coverage on your speciment while using the convenient and
economical 35mm film format
PHOTOGRAPHY AND TELEVISION

TELEVISION
For television the MA 151/5N (EMZ-TR) "C" Mount Adaptor should be used, threaded into your TV
camera, then placed and adjusted on the upper portion of your trinocular body.
Adjustment can then proceed a per paragraph (3) above. You should understand that the
comparatively large magnification factors inherent in most TV camera/monitor systems will restrict your
fields of view (while blowing up total magnification).
A correct optical set-up and adjustment is, of course, crucial to obtaining a good TV monitor image, but
keep in mind that the monitor controls for brightness and contrast adjustment are also important and
should also be experimented with in order to obtain the best monitor image.
CAMERA OPERATION
(1)
(2)
(3)
Fix your 35mm SLR camera on the MA150/50
or MA150/60 Camera Attachment, then
mounting this assembly on the straight tube of
the trinocular body.
Pull out the lever on your trinocular body so
as to send the image both to the camara and
the visual eyepiece.
Rotate the adjustment ring on the straight
tube so as to set the red indicator line on the
upper tube portion at the top edge of the lower
tube. Then fix in place with the clamp screw.
You now should be set correctly for optimum
conditions of simultaneous visual observation
and photography.

BULB REPLACEMENT
When changing light bulbs in the illuminators, always disconnect the plug from the electrical source.
Never work on the electrical system without first disconnecting.
When a bulb replacement is necessary in the Incident Illuminator, remove the lamp cover by turning it
counterclockwise and remove the old bulb by twisting it 1/3 turn counterclockwise by pushing it toward
the socket so that the bulb will be sprung out from its socket.
To replace the bulb of the Transmitted Illuminator, lay the instrument carefully over on its side and
remove the four set screws in the bottom cover of the base. Replace the old bulb in the same way as
above.
The bulbs used for the Incident and Transmitted Illuminators of PB/ABZ stand are different. The bulb
for the Incident Illuminator employs a flat filament facing to the head of the bulb and Catalog Number is
MA560 and the bulb for the Transmitted Illuminator employs a flat filament facing to the side of the
lamp and the Catalog Number is MA561. The bulbs used for the Incident and Transmitted Illuminators
of PBH/ABZH/ABEstand are same halogen. Catalog number is MA570.
CARE
Always cover the instrument with the plastic dust cover provided when the microscope is not in use.
Keep the eyepieces in the microscope body at all times in order to prevent dust from falling on the
internal optics.
Store the microscope in a safe, clean place when not in use for an extended period of time.
CLEANING
Clean exposed lens surfaces carefully with a pressurized air source, soft brush or clean soft cloth.
Too much finger pressure may damage lens coatings.
To remove oil fingerprints and grease smudges, moisten the cleaning cloth with a very small amount of
alcohol or xylene.
Painted or plastic surfaces should be cleaned only with a cloth moistened with water and a small
amount of detergent.
DO NOT ATTEMPT TO MAKE ADJUSTMENTS TO THE INTERNAL OPTICS OR MECHANICS!!
If the microscope does not seem to be functioning properly or you have questions about its operation,
call your supplier (or an authorized repair service) for advice.
