Stereoscopic microscopes are used for viewing 3-dimensional objects, inspection or assembly of small parts, and for dissection of
biological specimen. They provide an upright, unreversed image which permits easy manipulation of the object being viewed while
Notice: The first three digits of the model number, for example 440- 4 -or 4 0T , represent the optical
portion of your microscope. Thus, all models star h 4 0 have the same binocular head, and all ting wit 4
models starting with 440T have the same trinocular head. Procedures for use of the head are the same,
regardless of the stand supplied with your specific model.
The digits following the first – (dash) represent the stand portion of your microscope. The different
stands available have features and functions unique to each.
You made your selection of stands when you originally purchased your microscope. The above
explanation is provided so that when ordering and installing replacement bulbs you use the correct bulb
for your particular model number.
Models with PLL have the dual LED base
Models with P have the Plain base

looking through the microscope. They are designed for viewing solid objects at low magnification, but they will also permit viewing of
some transparent specimen slides.
For optimum viewing satisfaction, follow these simple procedures. Nomenclature used to describe components and controls can be
identified by referring to the diagram at left.
UNPACKING
1. Carefully remove microscope stand and head assembly from cartons. Remove rubber eye shields eyepieces, , frosted stage plate,
dustcover, and used for changing stage plates) dy “L” hex key wrench ( . The black/white contrast plate (80mm diameter) is alrea
mounted in the microscope base. (Models withP do not include frosted stage plate, “L .)” hex key wrench
2. Make certain not to touch any of the lens surfaces while handling the microscope. Dust, dirt, fingerprints can damage th e delicate
lens surfaces or adversely affect image quality.
3. Examine packing material before you discard it. Retain the styrofoam container in case you need to transport, store, or
return the microscope for service. If it becomes necessary to ship the microscope for any reason, pack it in the styrofoam
container, and then pack the styrofoam in another corrugated shipping container for optimum protection. Use of the styrofoam
alone will not provide adequate protection in transit and will void your warranty.
ASSEMBLY
1. Mounting the stereo zoom head to stand
A. Loosen head locking screw and head retaining screw.
B. Insert head into the stand (do not force), positioning head to face either forward or backward, whichever suits your preference
or needs.
C. Tighten head retaining screw and head locking s crew.
2. . Install rubber eyepiece shields over top of eyepieces
OPERATION
1. ILLUMINATION (only for models with illuminators)
A. Before operating mi croscope, adjust intensity control located on side of base to the minimum position. This should be done
prior to each time light is turned on or off. Failure to do so will significantly shorten bulb life.
B. Make certain that the main voltage of your microscope corresponds to the voltage of your power outlet, either 120v or 220v.
Insert microscope plug into matching voltage outlet.
C. The microscope is furnished with two stage plates. The frosted glass plate is used when viewing transparent specimen slides
or for viewing some specimen thin enough through which light can pass (insect wings, etc.) The plastic black/white contrast
plate can be used when viewing opaque objects or for dissecting. Choose side of plate providing best contrast with specimen.
D. wo There are t rocker type light controls located on top surface of microscope base.
“I” = Turns incidental light on (top illumination)
“T” = Turns transmitted light on (substage illumination)
NOTE: USE TRANSMITTED ILLUMINATION ONLY WITH FROSTED GLASS STAGE PLATE IN PLACE. HEAT
GENERATED IN BASE FROM BOTTOM LIGHT WILL WARP OR DAMAGE THE PLASTIC BLACK/WHITE PLATE. SUCH
DAMAGE WILL NOT BE COVERED BY WARRANTY.
Remove black/white stage plate by loosening locking set screw located on front of base with supplied “L” wrench. Install
frosted glass stage plate. Tighten locking set screw.
Incidental illumination can be used with either frosted glass plate or black/white plastic stage plate. The top light has an
intensity control located on side of base. When using incidental light, always set intensity control at its lowest level before
turning lamp on or off. This measure will extend bulb life. The top light can also be centered on specimen by using the top
light beam adjustment screw. This allows user to select the best spot illumination required for specimen being viewed.
Transmitted and incidental illumination combined can provide extra illumination for certain objects where additional top
illumination will enhance the object being viewed.

2. INTERPUPILLARY ADJUSTMENT
This permits each user to adjust spacing between eyepieces in order to accommodate distance between their eyes. While
looking through the microscope eyepieces with both eyes, grasp eyepiece tube housings with both hands and rotate them on
their axis, moving eyepieces apart or together until a full field of view is observed and pupillary images blend into one. Inter
distance is now corrected for your own inter ocular distance and does not require further adjustment later unless another user -
changes this adjustment.
3. FOCUSING
A. Adjust zoom control knobs (located on bot h sides of head) so that the lowest magnification number “1is positioned at the
black index dot on head. Lower magnifications have larger fields of view, making it easier to position and locate area to be
viewed.
B. Place a flat object or specimen slide ( cover glass up), on stage plate.
C. Position focusing knobs in the center of focusing range.
D. On post mounted models, the height of viewing head can be adjusted up or down on the post in order to focus on difference
sized objects. Loosen the locking knob located on the locking support collar, allowing the support collar to slide down to
bottom of post. While firmly holding viewing head with one hand, loosen locking knob located on back of focusing assembly
so that head can move freely up or down on post.
W hile looking through microscope, move viewing head up or down on post until object can be seen in approximate focus.
Tighten focusing assembly locking knob. Position the support collar under the focusing block and tighten locking knob on
support collar. It is not necessary to make this adjustment every time you change objects to be viewed, so long as the
different objects are of similar thickness or height.
E. Both eyepieces have knurled diopter adjustment rings. Rotate both left and right diopters in a clockwise direction to the lowest
position.
F. Adjust zoom control to the highest magnification by aligning the number “4” on knob to the black index dot on head.
G. While looking through right eyepiece with one eye, rotate focusing control knob until specimen comes into sharp focus through
right eyepiece.
H. Adjust zoom control knob to the lowest magnification.
I. Adjust the right diopter until the image is sharp. Do not change the focusing knob position.
J. Without changing the position of the focusing knob, adjust the left eyepiece diopter until you obtain a sharp image in left
eyepiece. the image should now be sharp throughout the zoom power range.
