Important
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. Be sure to
remove the specimen before moving this product.
· Hold the bottom of the stand with one hand while holding base column with the other hand
to avoid tilting the micro-scope.
· In case the specimen is damaged by erroneous operation, promptly take the infection
prevention measures.
2. The desktop should be a level surface with an inclination of less than 3°, and the load to the
microscope should be less than 7 kg (when the SZ2-ST standard stand is used).
The microscope may become unstable when certain intermediate attachment and/or photography unit are
mounted on it. Be careful so that the microscope does not topple down.
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, dust or
vibrations. (For the operating conditions, see “6 Specifications” (P. 14).)
3. Do not turn the zoom adjustment knobs beyond the stopper positions. Otherwise, the internal mechanism may be
damaged.
Do not turn the left and right zoom adjustment knobs in the opposite directions, as this will result in a failure.
4. Only one intermediate attachment having thickness up to 60 mm can be mounted on the microscope. If two
intermediate attachments or an intermediate attachment thicker than 60 mm is mounted, the image may be cut a
little.
However, the coaxial reflected light illuminator (SZX-ILLC) is not counted in the number of intermediate attachment.
When using multiple modules, they should be stacked in order of the SZX-ILLC, SZX-AS, SZX-RFA, SZX-SDO2
and SZX-EPA from the bottom to the top.
TIP
The SZX7 stereomicroscope is provided with the ESD (Electro-Static Discharge) protection specifications. It is provided with
electroconductive coating in the external finish to reduce the surface resistance and grounding lead wires in their standard
stand or system to eliminate static electricity from them.
To maintain the ESD protection performance, always use the microscope in combination with the
modules described in this manual or options having the ESD protection specifications. Otherwise, the
grounding will not work properly.
CAUTION
Safety precautions
1Getting ready

2
If the microscope is used in a manner not specified by this manual, the safety of the user may be imperiled. In addition,
the equipment may also be damaged. Always use the equipment as outlined in this instruction manual.
The following symbols are used to set off text in this instruction manual.
CAUTION : Indicates that failure to follow the instructions in the warning could result in
bodily harm to the user and/or damage to equipment (including objects in the
vicinity of the equipment).
NOTE
: Indicates that failure to follow the instructions could result in damage to equipment.
TIP
: Indicates commentary (for ease of operation and maintenance).
3Caution
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. Do not attempt to use organic solvents to clean the microscope components other than the glass components
because they use plastic resin materials extensively. To clean them, use a lint-free, soft cloth slightly moistened with
a diluted neutral detergent.
3. Do not disassemble any part of the microscope as this could result in malfunction or reduced performance.
4. When disposing of the microscope. Check the regulations and rules of your local government and be sure to
observe them.

4-1 Stand
When reflected light illumination is used, the stage plate can be
placed either the white or black surface facing up depending on the
specimen. However, when the ESD performance is required, always
use the black surface of the stage plate.
When transmitted light illumination is used, use the transparent glass
stage plate (SP-C).

This operation is intended to facilitate the rotation of the
knobs while preventing 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.
Hold the left and right focus adjustment knobs awith both hands,
fix the left knob and rotate the right knob. The rotation tension of the
knobs increases or decreases according to the direction in which the
right knob is rotated.
If the rotation tension is increased too much, accurate focusing is not
possible and the mechanism may be damaged.

Diopter scale of the 10X eyepieces
The valid range of the diopter scale is between -8 and +5 but
a slight margin is added to it. Therefore, the diopter value may
exceed +5 or -8 when it is adjusted to the maximum. In this
case, whether the diopter value is over +8 or under -5 can be
identified by the length of the eyepiece.
TIP
-8 +5
The eye shades are not provided with ESD protection
performance. When ESD protection is required, do not use the
eye shades.
When Wearing Eyeglasses
Use with the eye shades in the normal, folded-down position. This will
prevent the eyeglasses from being scratched.
When Not Wearing Eyeglasses
Extend the folded eye shades in the direction of the arrow to prevent
extraneous light from entering between the eyepieces and eyes.

Gently screw in the disk-mounting ring cincorpofrating the eyepiece
micrometer disk into the eyepiece. Turn the ring clockwise to attach it firmly.
Due to their structures the WHSZ20X-H/30X-H eyepieces
apply a magnification on the focused plane of the eyepiece
micrometer disk.
These magnifications are 1.3X with the WHSZ20X-H and 2X with
theWHSZ30X-H.Be sureto compensatefor thesemagnifications
when using the eyepiece micrometer disk in measurements.
Also, insertion of the eyepiece micrometer disk extends the
light path length and deviates the position of the diopter
scale. Correct this deviation by turning the diopter adjustment
ring of the eyepiece toward “+”.
When the eyepiece micrometer disk is not used, store it by
wrapping in a clean, soft cloth.

3Using auxiliary sleeve SZ2-ET (option)
As the 0.5X objective has a long working distance, it cannot be used in
combination with the standard stand unless the auxiliary sleeve is used.
When the auxiliary sleeve is used, the microscope
becomes tall and unstable. Care is therefore needed
against toppling it down.

A digital camera unit can be mounted on the trinocular tubes by means of the camera adapter and/or camera mount
adapter *.
* The camera mount adapter is not necessary if a camera adapter equipped with a camera mount is used.
For details, please also read the instruction manuals for the camera adapter and digital camera.
Using the Allen screwdriver, fully loosen the straight tube clamping
screw aof the straight tube mount on the top of the trinocular tube.
Fit the round dovetail bof the camera adapter into the straight tube
mount of the trinocular tube, and tighten the clamping screw a.
Mount the camera on the camera adapter. A camera mount adapter
may be required with certain camera adapters.
