1. Warning
This microscope is a scientic precision instrument designed to last for many years with a minimum of maintenance. It
is built to high optical and mechanical standards and to withstand daily use. We remind you that this manual contains
important information on safety and maintenance, and that it must therefore be made accessible to the instrument users.
We decline any responsibility deriving from incorrect instrument use uses that does not comply with this manual.
2. Safety Information
Avoiding Electrical Shock
Before plugging in the power supply, make sure that the supplying voltage of your region matches with the operation voltage
of the equipment and that the lamp switch is in o󰀨 position. Users should observe all safety regulations of the region. The
equipment has acquired the CE safety label. However, users have full responsibility to use this equipment safely. Please
follow the guidelines below, and read this manual in its entirety to ensure safe operation of the unit.
3. Unpacking
The microscope is housed in a moulded Styrofoam container. Remove the tape from the edge of the container and lift the
top half of the container. Take some care to avoid that the optical items (objectives and eyepieces) fall out and get dam-
aged. Using both hands (one around the arm and one around the base), lift the microscope from the container and put it
on a stable desk.
Do not touch with bare hands optical surfaces such as lenses, lters or glasses. Traces of grease or other
residuals may deteriorate the nal image quality and corrode the optics surface in a short time.
4. Intended use
Standard models
For research and teaching use only. Not intended for any animal or human therapeutic or diagnostic use.
5. Symbols and conventions

8.1 Adjusting interpupillary distance
1. Hold the right and left eyepiece tube with both hands and ad-
just the interpupillary distance by moving the two parts until
one circle of light can be seen. (Fig. 26)
• If two circles appear, the interpupillary distance is too big,
and if two overlapped circles appear, the interpupillary dis-
tance is too small.
8.2 Focusing
Put the sample to be observed on the stage plate and focus the
sample using the focusing knobs ①.
• If necessary adjust the height of the microscope head along
the vertical stand.
• Remember to lock the xing knob ② after setting the height
of the microscope. (Fig. 27)
8.3 Adjusting the tension of the focus knob
• This adjustment allows to increase or decrease the ten-
sion of the knob by avoiding an involuntary descent of
the microscope body under its own weight. Adjust the
tension just above the point where the focus is stable.
1. Grab the knobs ③ both hands and, while holding the left
knob, turn the right knob.
• The tension increases or decreases depending on the direc-
tion of rotation of the right knob. (Fig. 28)
8.4 Diopter compensation
• This compensation makes possible for people wearing
glasses to adjust the microscope to their eyes and use
the microscope without glasses.
1. Put the zoom down to the lowest magnication ④ and focus
the specimen with the focusing knobs ⑤. (Fig. 29)
2. Put the zoom to the maximum magnication and repeat the
focusing.
3. Return to the lowest magnication: the specimen will be out
of focus.

8.6 Use of additional lens
1. Screw the desired additional lens on the microscope body.
(Fig. 32)
• The stroke of the focus adapter could not compensate the
di󰀨erent working distances of the several additional lenses.
• In the event that the focus support fails to focus the sample,
the entire body of the microscope must be raised or lowered.
Total magnication used can be calculated as:
Eyepiece magnication * Zoom magnication * Objective lens
magnication.
4. Adjust the diopter compensation ring of the right eyepiece
⑥ (Fig. 30) until the image of the right eyepiece is clear and
sharp. Repeat the procedure for the left eyepiece.
5. Check the focus of the image for the whole zoom range. It
should be perfectly parfocal (focus is maintained during the
change of magnication).
FFig. 30ig. 30
8.5 Magnication
1. Select the desired magnication by adjusting the zoom knob
①. (Fig. 31)
• Change the eyepieces and/or add an appropriate additional
lens if needed.

8.8 Use of illumination (OS-SZ1 / OS-SZ2)
1. Move the main switch ①to turn ON the power supply. (Fig.
34)
2. Turn the transmitted light knob ② to change the intensity of
the transmitted light LED.
3. Turn the incident light knob ③ to change the intensity of the
incident light LED.
• It is possible to use both illuminations at the same time.
8.7 Black/white stage plate (OS-SZ1 / OS-SZ2)
• You can use a black/white contrast disc to increase the
contrast of the image when working in incident light. (Fig. 33)
1. If you are looking at bright samples, place the disc with the
black part facing up.
2. If you are looking at dark samples, place the disc with the
white part facing up.

10. Maintenance
Microscopy environment
This microscope is recommended to be used in a clean, dry and shock free environment with a temperature of 5°-40°C and
a maximum relative humidity of 75 % (non condensing). Use a dehumidier if needed.
To think about when and after using the microscope
• The microscope should always be kept vertically when moving it and be careful so that no moving
parts, such as the eyepieces, fall out.
• Never mishandle or impose unnecessary force on the microscope.
• Never attempt to service the microscope yourself.
• After use, turn o󰀨 the light immediately, cover the microscope with the provided dust-cover, and keep
it in a dry and clean place.
Electrical safety precautions
• Before plugging in the power supply, make sure that the supplying voltage of your region matches
with the operation voltage of the equipment and that the lamp switch is in o󰀨-position.
• Users should observe all safety regulations of the region. The equipment has acquired the CE safety
label. However, users do have full responsibility to use this equipment safely.
Cleaning the optics
• If the optical parts need to be cleaned try rst to: use compressed air.
• If that is not su󰀩cient: use a soft lint-free piece of cloth with water and a mild detergent.
• And as a nal option: use the piece of cloth moistened with a 3:7 mixture of ethanol and ether.
• Note:ethanolandetherarehighlyammableliquids.Donotusethemnearaheatsource,nearsparksornear
electric equipment. Use these chemicals in a well ventilated room.
• Remember to never wipe the surface of any optical items with your hands. Fingerprints can damage the optics.
• Do not disassemble objectives or eyepieces in attempt to clean them.
Forthebestresults,usethededicatedcleaningkit.
