IMPORTANT
SAFETY PRECAUTIONS
1. After the equipment has been used in an observation of a specimen that is accompanied with a potential of infection,
clean the parts coming in contact with the specimen to prevent infection.
· Moving this microscope is accompanied with the risk of dropping the specimen and causing infections. Be sure to
remove the specimen before moving this product.
· In case the specimen is damaged by erroneous operation, promptly take the infection prevention measures.
· The microscope may become unstable when certain intermediate attachments and/or photography unit are mounted
on it. Take the measures so that the microscope does not turn over.
Fig. 1
2. To prevent the microscope body from turning over, its left-right pivot angle
must be limited to 30° as shown in Fig. 1. The tilt of the desktop surface
should be no more than 5°.
3. Sufficient care is required during observation with a low-magnification
objective, because the objective’s long WD (Working Distance) can
displace the microscope body to a higher position.
The measures for prevention of turning over are also required when using
an auxiliary pillar (SZH-P400/P600), because this also makes the
microscope body to be displaced to a higher position.
4. To adjust the microscope body height, be sure to hold the microscope
body with one hand while loosening the focusing assembly clamping
knob @. (Fig. 1)
(Use the drop prevention collar (SZX-R) to prevent a hazard from occurring.)
Be careful not to pinch your finger during the adjustment.

1Getting Ready
1. A microscope is a precision instrument. Handle it with care and avoid
subjecting it to sudden or severe impact.
2. Do not use the microscope where it is subjected to direct sunlight, high
temperature and humidity, or vibration. (For the operating environment,
see Chapter 6, “SPECIFICATIONS” on page 16.)
3. When moving the microscope, remove the specimen in advance. Then,
hold the front part of the base with one hand and hold the rear part of the
base with the other hand to avoid tilting the microscope.
Also remove any module or attachment from the microscope to minimize
the weight before moving.
4. Observe the following cautions when operating the coarse focus
adjustment knob or the zooming knob.
Operation Manipulated Controls Caution
Focusing Coarse/fine focus
adjustment knobs @
(Fig. 3)
1. If the knob hits the upper or lower
limiting mechanism violently or
it is rotated after it hits a limiting
mechanism, the internal
mechanism may be damaged.
2. If the knobs on the left and right
are rotated in opposite directions,
the internal mechanism will be
damaged. (The rotation tension
of the coarse focus adjustment
knob should be adjusted using
the rotation tension adjustment
ring ³ on the knob.)
Zooming Zooming knob ²
(Fig. 3) 1. If the knob hits the upper or lower limiting mechanism violently or
it is rotated after it hits a limiting
mechanism, the internal
mechanism may be damaged.
2. If the knobs on the left and right
are rotated in opposite directions,
the internal mechanism will be
damaged.
Fig. 2
Fig. 3
5. Only one intermediate attachment can basically be used, but two
attachments may also be used though the peripheral part of the image
may be obscured.
For the coaxial vertical illuminator (SZX2-ILLC16) and reflected fluorescent
light illuminator (SZX2-RFA16), only either can be attached because they
must always be attached at the lowest position.
}The SZX2-ILLC16 is not considered to be an attachment. Therefore, the
SZX2-LBS can be mounted above it without any restriction.

2Maintenance and Storage
1. To clean the lenses and other glass components, simply blow dirty away using a commercially available blower and wipe
gently using a piece of cleaning paper (or clean gauze).
If a lens is stained with fingerprints or oil smudges, wipe it gauze slightly moistened with commercially available absolute
alcohol.
Since the absolute alcohol is highly flammable, it must be handled carefully.
Be sure to keep it away from open flames or potential sources of electrical sparks -- for example, electrical
equipment that is being switched on or off.
Also remember to always use it only in a well-ventilated room.
2. The equipment uses plastic resins extensively in its external finish. Do not attempt to use organic solvents to clean them
but simply wipe them using a lint-free, soft cloth. To clean an extremely dirty part, use a soft cloth lightly moistened with a
diluted neutral detergent.
3. Never disassemble any part of the microscope as this could result in malfunctions or reduced performance.
4. When not using the microscope, keep it covered with the dust cover provided. If a module containing a source of heat is
mounted on the microscope, wait until it has cooled down before covering.
5. This equipment should be disposed of by following the rules and regulations of your national or local government.

SUMMARY OF OBSERVATION PROCEDURE
3-1 Preparation
Ref. Page
1. Check and tighten the connection of each component, especially the observation tube................................................... (Page 20)
2. Check that the angled formed by the microscope body with respect to the base is less than the
turning-over prevention angle. .................................................................................................................................................................................................................................(Page 19)
3. Adjust the tension of the coarse focus adjustment knob. .................................................................................................................................................. (Page 7)
4. Confirm the correct settings.
3-2 Observation Procedure
1. Place a specimen on the stage. (Page 7)
2. Adjust the interpupillary distance. (Page 10)
3. Make diopter adjustment of the eyepieces. (Page 10)
(The adjustment procedure is variable depending on whether the eyepiece
micrometer disk is used or not.)
4. Set the zooming knob @ to the lowest zoom magnification and bring the
microscope into focus by rotating the coarse focus adjustment knob ².
5. Rotate the zooming knob @ to the desired magnification and precisely
focus the microscope on the specimen with the coarse focus adjustment
knob ² and fine focus adjustment knob ³ (the fine focus adjustment
knob is not provided with the SZX2-FO).

USING THE CONTROLS
4-1 Base
1Using the Stage Plate
In reflected light observation, the stage plate can be placed either the
white or black side facing up.
#Win transmitted light observation, use the transparent glass stage
plate (SP-C).
2Placing the Specimen
1. Place the specimen on the approximate center of the stage plate. Hold
the specimen with the specimen holder as required.
2. Illuminate the specimen with an illuminator selected according to the
specimen under observation.
4-2 Microscope Body and Focusing Assembly
Fig. 4
1Adjusting the Tension of the Coarse
Focus Adjustment Knob (Fig. 4)
}This operation is intended to facilitate the rotation of the knobs while
preventing the spontaneous drop of the microscope body. It is
recommended to set the knob tension to a slightly higher level than the
point where spontaneous drop occurs.
If the knobs are hard to move because of the weight of option modules
and/or TV camera mounted on the microscope body, it is recommended
to use the focusing assembly for heavy load (SZX2-FOFH).
#The tension of the coarse focus adjustment knob can be adjusted
with the tension adjustment ring @. Do not rotate the knobs on the
left and right in opposite directions, for this will damage the internal
mechanism.
1. Rotate the tension adjustment ring @ by inserting the Allen screwdriver
³ into the hole ² on the ring periphery.
Rotating the ring clockwise increases the tension of the coarse focus
adjustment knob, and rotating counterclockwise decreases it.
#If the microscope body falls down by its own weight or the focus
obtained by fine focusing is lost immediately, the tension adjustment
may be too light. In this case, rotate the ring clockwise to increase
the tension.
#If the tension adjustment is too tight, delicate focusing will be
impossible and the knob may be damaged. Particularly, to prevent
damage, never rotate the fine focus adjustment knob quickly while
its tension is extremely tight.

2Engaging and Disengaging the Zooming
Knob Click Stop Function (Fig. 5)
}When the click stop knob is set to ON, the click stop function is engaged
for each magnification indicated with the zooming knob. When the knob
is set to OFF, the zoom magnification can be varied continuously and
finely near the click groove.
The click stop knob has been set to OFF before the microscope is shipped
from the factory.
}A click stop is provided for each of the 12 intermediate indication positions
of the zoom microscope body.
1. To engage the click stop function, rotate the click stop ON-OFF screw @
fully clockwise (in the direction of the arrow) using the Allen screwdriver.
The zooming knob then stops at every position corresponding to the
magnification indicated on the zoom magnification indication ².
2. To disengage the click stop function, rotate the click stop ON-OFF screw
@ fully by three turns from the ON position, in the direction opposite to
the arrow, using the Allen screwdriver.
#Do not rotate the screw too much, or the cover may be damaged.
3Adjusting the Aperture Iris Diaphragm (Fig. 6)
}Adjusting the aperture iris diaphragm increases the contrast of the
observed image as well as the depth of focus.
However, setting the aperture iris diaphragm too narrowly degrades
resolution.
1. Adjust the aperture iris diaphragm ring @ to the left or right.
Rotating the ring toward the left (\) opens the aperture; rotating it toward
the right ( ) closes it. Adjust while monitoring the observed image to
confirm the contrast and focal depth improvement effects.
#Do not close the aperture too much, for this may cause degradation
in resolution and/or lack of ambient light.
2. Use the scale gradations as references for memorizing the ring position.
#When the microscope is combined with the coaxial vertical illuminator
(SZX2-ILLC16), minimizing the aperture may obscure a part of the
observed field of view. In this case, open the aperture to an intermediate
position.

4Zoom Magnification Indication (Fig. 7)
The body zoom magnification is indicated on the zooming knob on the
right side.
The total magnification of observation can be calculated with the following
formula:
52X Objective Collection Collar (Fig. 8)
}The SDFPLAPO2XPFC objective is provided with a correction collar @ for
use in compensating for the aberration caused due to the observation
medium such as water and plastic container.
When observing a specimen in a liquid or through a petri dish cover, turn
the collar to obtain the optimum contrast.
· Correction is possible for aberration corresponding to water depth of
about 5 mm.
· The correction effect may be less tangible when the zoom magnification
is low or the aperture iris diaphragm is stopped down.
}When using the SZX2-2RE16 revolving nosepiece, hold the objective
during rotation of the ring so that the revolving nosepiece is not deviated
the click position.

1Adjusting the Interpupillary Distance (Fig. 9)
#Be sure to hold the binocular assembly @ with both hands to make
this adjustment.
To prevent damaging the mechanism, do not apply an excessive
force beyond the stop position.
While looking through the eyepieces, hold the left and right of the binocular
assembly @ and adjust the eyepieces by opening or closing them for
binocular vision until the left and right fields of view coincide completely.
2Adjusting the Diopter
(Zoom Parfocal Adjustment) (Fig. 10)
}Ensure that the eyepiece clamping knob @ is tightened before starting
the adjustment.
Adjusting the diopter specific to the two eyes of each observer allows the
parfocality to be ensured across zoom magnifications.
When Not Using the Eyepiece Micrometer Disk
1. Look into the right eyepiece and rotate its diopter adjustment ring ² so
that the peripheral part of the visual field looks sharply.
2. Place an easy-to-observe specimen on the stage plate.
3. Rotate the zooming knob ³ to a low magnification and, looking only into
the right eyepiece, focus the specimen using the coarse and fine focus
adjustment knobs.
4. Rotate the zooming knob ³ to the highest magnification and, looking
only into the right eyepiece, focus the specimen using the coarse and
fine focus adjustment knobs.
5. Rotate the zooming knob ³ to the lowest magnification, look only into
the left eyepiece, and focus the specimen by rotating the left diopter
adjustment ring | instead of the coarse and fine focus adjustment knobs.
When Using the Eyepiece Micrometer Disk
1. Look into the right eyepiece that includes the eyepiece micrometer disk,
and focus the micrometer disk by rotating the diopter adjustment ring ².
2. Place an easy-to-observe specimen on the stage plate.
3. Rotate the zooming knob ³ to the highest magnification and, looking
only into the right eyepiece, focus the specimen using the coarse and
fine focus adjustment knobs.
Ensure that both the eyepiece micrometer disk and specimen are focused
accurately.
4. Rotate the zooming knob ³ to the lowest magnification, , look only into
the left eyepiece, and focus the specimen by rotating the left diopter
adjustment ring | instead of the coarse and fine focus adjustment knobs.
}Note (or memorize) the diopter readings of the left and right eyepiece
scales so that they can be duplicated quickly in the next observation.

3Using the Eye Shades (Fig. 11)
When Wearing Eyeglasses
Use with eye shades in their normal folded-down position. (This will prevent
eyeglasses from being scratched by the eyepiece.)
When Not Wearing Eyeglasses
Extend the folded eyeshades in the direction of the arrow. This makes
observation easier by preventing the inverse incidence of light from
between the eyepiece and your eyes.
4Using the Eyepiece Micrometer Disk (Fig. 12)
}A variety of eyepiece micrometer disks can be inserted into the WHN10X-
H, WHSZ15X-H and WHSZ20X-H eyepieces.
1. Unscrew the ring @ by turning it counterclockwise to remove it from the
bottom of the eyepiece.
2. Clean the eyepiece micrometer disk ² ( 24 mm, thickness 1.5 mm) to
remove dust and dirt, then place the disk into the ring @ so that the side
with reticule faces downward.
3. Attach the ring @ with the eyepiece micrometer disk ² by gently screwing
it onto the eyepiece.
#The WHSZ20X-H eyepiece is designed to apply a magnification to
the focusing plane of the micrometer disk.
As the magnification coefficient is 1.35, be sure to perform magnification
compensation when using this eyepiece in measurement.
When the micrometer disk is engaged in their light path, the light
path length will extend and the diopter scale may deviate toward
the + direction from the normal indication. However, this does not
pose any problem in actual observation.
}When the eyepiece micrometer disk is not used, wrap it in a clean sheet
of soft paper before storage.
