2.1 Installation Site
The microscope should be operated in a room with as little dust and debris as practically
possible. Keep your instrument away from solvents, chemical fumes and excessive
humidity. Also try to avoid big swings in ambient temperature, direct sunlight and
vibration as they can affect measurements and instrument performance.
Operating Ambient Conditions
Temperature: 10 - 36°C (50 – 96.8°F)
Relative Humidity: 0 – 80% up to 30°C (86°F)
2.2 Unpacking
Please check your packing slip to insure that all materials are present. Keep a copy for
your records so that you have the proper information when ordering more equipment,
ordering replacement parts or accessories or when calling for technical support. Please
make sure that no small pieces or parts are left in the packing material. Keep the packing
materials in a safe place for the purpose of storage and transporting the microscope and
its accessories.
Avoid touching the surface of optical components such as lenses,
filters and glass surfaces. Even very small traces of perspiration or finger oils can corrode
the surfaces of optics in a short period of time.

2.3 Microscope Set Up
•As a first step, remove all components from the shipping container and remove
the packing materials and place the microscope frame on a stable work surface.
•Loosen the clamp screw on the microscope limb and install the vertical
illuminator (MA806). Once the thumbscrew is tightened, place the binocular or
trinocular head (MA657/05 or MA655/05) onto the top of the illuminator and re-
tighten the clamp screw while the head is in the correct position.
•Install the two eyepieces (MA406 and MA413CF) by sliding them into the head
and then install the rubber eyeshields on top of each eyepiece. The MA413CF
focusing eyepiece installs on the right hand side. The shiny pin aligns the
crosshair reticle into the slot on the eyetube.
•Remove the objectives from their objective cases while being careful not to touch
any part of the optics. Then, screw each objective into a nosepiece opening. Install
them incrementally or in order of power (e.g. 5, 10,
20, and 50).
•Un-package each digital micrometer and install the
two 164-162’s into the stage. One may need to
loosen the Allen bolts that clamp the micrometers
into place. If a Z-axis micrometer was purchased,
install it onto the focus block as seen at right.
•Insert the fiber optic light guide into the vertical
illuminator and tighten it in place with the two
Allen screws on the port. Next, plug the power
cordset into the fiber optic light source and the other
end into a grounded outlet.
The mains power cord should only be plugged into a known grounded outlet.
A simple outlet tester can be used to verify correct outlet polarity and the presence of a
grounded circuit. If no other accessories are going to be installed, the instrument is now
ready for use.

2.4 Adjusting Interpupillary Distance
The Interpupillary Distance is essentially the distance
between your two pupils expressed in millimeters. When
set correctly, one will see one uniform round field of
view or FOV. The adjustment is made by simply pulling
apart or pushing together the eyetubes until a uniform round field is achieved.
Make note of the number marked on the viewing head so
you can repeat the setting later. The number indicated on
the microscope head is your IP expressed in millimeters.
That number will also need to be dialed up on the left
eyetube as shown at right.
Once this is done, the microscope is adjusted to this user. Other users will have
different IP’s and different focusing abilities so re-adjustment is necessary.

3.0 Operation
Once the microscope has been setup in its working location with all of the components
correctly installed, it is ready for use.
Your MC microscope is a precision instrument designed to last a lifetime. Always handle
your microscope with care and avoid abrupt motion, vibration and shock.
Do not install any bulb in your instrument other than ones designated by Meiji Techno:
FL150/70 21V 150W Halogen For Fiber Optic Illuminator FL150 or FT190 Series
Avoid Dismantling
Never attempt to dismantle the instrument. This will void your warranty and could
possibly lead to the instrument no longer performing accurately.

3.1 Incident Light Operation – Brightfield
1. First, set your interpupillary distance on the
microscope eyetubes by pulling them apart or
pushing them closer together to fit your eyes. When
set correctly, one will see one uniform round or
“fused” field of view. Make note of the distance
setting when adjusted to your liking so you can later repeat the setting.
2. Turn on the power to the fiber optic illuminator. Adjusting the brightness desired
is done with the variable brightness control knob on the front of the illuminator
power supply.
3. Make sure the field iris diaphragm on the vertical illuminator is opened all the
way open to start.
4. We recommend that you initially use a flat, easily recognizable specimen like a
coin to setup your microscope. Place that specimen on the stage.
5. Select a lower power “scanning” objective like the 5X or the 10X to find the area
of interest on the specimen quickly. Be sure the objective “clicks” into place when
you turn the objective nosepiece.
6. The aperture iris diaphragm located on the vertical illuminator can be "stopped
down" or closed somewhat to give the observation of your specimen more or less
contrast or resolving power. Stopping down the diaphragm decreases resolution
and brightness but increases image contrast and depth of focus.
Possible Brightfield Mode Operational Problems
If normal adjustments are not getting the results you expect, check to see if these
conditions exist:
•Incorrect components inadvertently installed
•Components not mounted flush (Vertical Illuminator to microscope frame, etc.)
•Dirty or smudged optics
MC Series S.Plan Metallurgical Brightfield Objectives
Brightfield Objectives – Plan Episcopic - Infinity Corrected - F = 200mm
MA330 S.Plan M5X objective, NA: 0.10, WD = 20.0mm (included)
MA337 S.Plan Epi 10X objective, NA: 0.25, WD = 9.4mm (included)
MA338 S.Plan Epi 20X, objective, NA: 0.40, WD = 5.28mm (optional)
MA339
MA328 S.Plan Epi 40X objective, NA: 0.65, WD = 0.81mm (included)
S.Plan Epi 100X objective, NA: 0.75, WD = 0.27mm (optional)

3.3 Using the Polarizer
Polarizer
For certain specimens, the use of polarized
light will enhance the contrast and facilitate
viewing of difficult to see object features.
The polarizing filter is engaged by dropping
it into one of the filter slots located along
the top of the illuminator tube as shown in
the drawing below.
Slide-In Analyzer
The analyzer is mounted in a slider which is located right
below the viewing head as shown. It can be inserted or
withdrawn from the optical path by grabbing the chrome
knob and sliding it east-west in its slot.
The lever on the side rotates the filter between 0 and 90
degrees as shown at right.
With the polarizing filter in place and the analyzer
engaged and the lever set at 45 degrees, the polarizing
elements are said to be “crossed” and the field of view
will become darker or “extinguished”.
In this condition, the field of view is dark except for the optically active elements within
the field which become visible against the dark background.

3.4 Photomicrography with 35mm SLR and Digital SLR
Cameras
The MC Series microscopes can have a trinocular tube on top of the head for use in
photomicroscopy.
In order to secure a 35mm SLR camera body to the trinocular or photo tube, an optional
camera attachment tube (MA150/50 or MA150/60) will need to be used with the
corresponding T2 Adapter Ring that matches the camera to be used.

4.0 Maintenance and Cleaning
•Disconnect the power cord on your equipment prior to performing cleaning,
maintenance or repair.
•Keep electrical components away from moisture or humidity.
•In warm humid climates, take special care to prevent your equipment from
exposure to fungal growth by using desiccant in an airtight storage container or by
other means.
•Clean the microscope after each use. Keeping your microscope clean will insure
its proper operation over its lifetime.
Cleaning
Dust, fibers and other debris can cause your field of view to get obstructed so keeping
your microscope clean will help the overall quality of your work.
Cleaning of Painted Surfaces
Use a soft brush or lint-free cotton cloth to removed dust and loose particles. Tough dirt
can be removed with water and a mild detergent.
NEVER USE ACETONE OR OTHER HARSH CHEMICALS.
Painted or plastic surfaces should not be tarnished or etched with cleaning agents that are
too powerful.
To clean painted surfaces, use a moistened lint-free cotton cloth with mild soapy water.
Cleaning the Stage
Use a soft brush or lint-free cotton cloth to removed dust and loose particles.
DO NOT USE ACETONE OR OTHER HARSH CHEMICALS, use a moistened lint-
free cotton cloth with a solution of mild soapy water.
Cleaning of Glass Surfaces

Use a soft brush or lint-free cotton cloth to removed dust and loose particles.
For tough dirt, use a soft lint-free cotton cloth moistened with distilled water.
If that fails, try using medical or reagent grade isopropyl alcohol.
Cleaning the Objectives
Objectives should NEVER be disassembled for cleaning or for any other reason! We do
not advise cleaning the inside surfaces of objectives or eyepieces.
Use a soft brush, bellows brush or a soft lint-free cotton cloth to removed dust and loose
particles.
For tough dirt, use a soft lint-free cotton cloth moistened with distilled water.
If that fails, carefully try using medical or reagent grade isopropyl alcohol.
Wipe lenses immediately. Over time, water and solvents can dissolve optical cements that
hold optics together so NEVER soak objectives with ANY type of fluid.
