IV. Assemblage
1. Assemblage
1) Assemblage of the Stage
Place the stand on a stable table, insert the stage into the base, and tighten the fixing screw with
wrench (small) attached at the back of the stand.
Note: The stage must be placed at plane table.
2) Lifting of the Focus Arm
The focus arm can be adjusted according to your special demands. Loosen the screw with the
wrench ( big ), and the arm will 55mm lower than before after re-mounting the focus arm.
Note: Before tightening the screw, make sure that the 2 pins on the arm fit into the grooves on the
vertical slider.
3) Mount the Zoom head
Tighten the fixing screw of the zoom tube slightly to fix the zoom head on the stand.

Warning: Do not tighten the screw too tight as this will make damage to the instrument.
4) Mount the Eyepiece
Rotate the eyepiece to 0, and insert the eyepiece into the tube completely till it touches the end of
the tube.
Note: when inserting the 10x eyepiece, make sure to touch the end of tube.When inserting or
extracting the eyepiece, please hold the cap instead of the diopter ring.
5) Wrenches are put at the Back of the Stand.
6) Image Recording digital camera. To satisfy your special requirements, kinds of interface are
supplied for your choosing, and this will make your operation and observation more convenient.
a. Assemblage of 0.4x reduce lens and the digital camera
Take away the dust-cover of the trinocular, insert one end of the 0.4x reduce lens into the digital
camera and tighten it. Insert the other end into the trinocular port, adjust the CCD, and tighten it.

b. Assemblage of the DSLR Camera Adapter and Digital SLR Camera
Take away the dust-cover, screw one end of the DSLR camera adapter into the DSLR camera.
Insert the other end of the camera adapter to the trinocular head, and tighten it. Adjust the camera,
and tighten it.
V. Operation
1. Preparation
1) Illumination
Insert the power supply source into the socket of the transmitted base, connect the power supply
source and turn on the switch. Adjust the brightness. It is not necessary to adjust the brightness to
the strongest as this will reduce the life of the bulb.

2) Adjust the torque of focusing knob
Adjust the torque of the focus knob so that the zoom body will not fall down because of its own
weight.
3) Interpupillary Distance Adjusting
This adjustment should be performed every time if the observer changes since the interpuillary
distance is different between individuals. Adjust the interpupillary distance so that the view field
for each eye is merged into one.
Move while holding each tube with both hands.
4) Diopter Adjusting
a. Set the zooming knob to the highest magnification (5x), focus on the sample using the focus
knob
b. Set the zooming knob to the lowest magnification (0.8x), look into the left eyepiece with your
left eye, focus on the sample using the diopter ring on the left eyepiece. Then look into the right
eyepiece with your right eye, and focus on the sample using the diopter ring on the right eyepiece.
c. Repeat Step a & b until the image is projected on the focus.
2. Focusing
1) Check the Working Distance
Working Distance is the distance between focus plane and zoom head. The W.D For BS-3035
series zoom stereo microscope is 115mm. Set the distance between the bottom of the zoom tube

BestScope International Limited

and specimen at 115mm, and this will be helpful to focus.
2) Focus on the Specimen
Turn the focusing knob both at the same direction to make the zoom tube move up and down. So
that the focus will fall on the specimen.
3) Magnification
Turn the zoom knob on both sides of the zoom tube to change the magnification of the specimen.
Total Magnification
Zoom knob on right has the indication of the zooming magnification. Total magnification can be
calculated by multiplying the eyepiece magnification by the zoom body magnification.
Note:When auxiliary objective is attached, multiply its magnification as well.
VI. Assemblage and Usage of the Attachments
1. Auxiliary Objective
Twist the auxiliary objective into the zoom body. Adjust the focus knob to a certain height.
2. Illumination
Three kinds of illumination are available for your special needs: Transmitted light, incident light
and LED Circuit light.

shown. Secure it in place using mounting screw from outside.
2) Install LED circuit illumination
Insert the fixing screw into the groove of the zoom body and tighten it.

VIII. Maintenance
1. Working Environment
● Temperature range is 0°C-40°C and the max. Humidity is 85%. Avoid high temperature and
humidification.
● Do not expose the microscope in the sun directly.
● Place microscope on a stable table and keep it in balance. Avoid violent vibration.
● Keep the environment clean and cover the microscope with the dust-cover.
2. Protect the microscope well
As microscope is a precision instrument, please avoid violent vibration. Improper using will make
it unworkable.
3. Lens cleaning
Avoid dust and fingerprint on the lens as these will reduce its precision. Please clean as the
following
1) Blow the dust with dust blower. Soft brush or gauze can also be used to remove the dust.
2) More persistent dirt, such as fingerprints and oil, may be removed with soft cotton or lens tissue
lightly moistened with absolute alcohol. As absolute alcohol are quite flammable, please take
great care when using.
4. Cleaning of the painted or plastic parts
Avoid using organic solvents (such as alcohol, ether, etc) to clean the painted or plastic parts of
the instrument.We recommend the use of gauze.
More persistent dirt may be cleaned with mild detergent solution.
5. Storage
When the microscope is not in use, cover it up with dust cover, and store in a dry place not subject
to mold. Do not expose the microscope in the sun directly, avoid high temperature and
humidification.
6. Periodical inspection
To maintain the performance of the microscope, periodical inspection is recommended.
