Cleaning And Maintenance - Bresser ANALYTH STR 10X-40X Instrucciones De Uso

3. Observation
Place the desired object in the middle of the stage (10) and secure it with the clamps (11) if
necessary. The objective's magnification (1x, 2x or 4x) can be adjusted by turning the objective
holder (12). It is recommended to start observations always with the lowest magnification
(1x). Now look through the eyepieces (1) at the binocular head (3). Adjust the sharpness with
the focuser (4).
4. Focusing and dioptre compensation
Set the dioptre scale (2) to to the middle position (shiny ring) and observe an object. Now
close your left eye and adjust the focus with the focuser (4) for your right eye. Then, close your
right eye and adjust the focus for your left eye with the dioptre scale. Now, the microscope is
adjusted for your eyes. Note the setting of the dioptre scale you need to use in future.
5. Eye distance
The Analyth STR is equipped with an adjustable binocular head. To set your eye distance,
move the eyepieces against each other until you found the ideal position.
6. Replacing the Eyepieces (optional)
To replace the eyepieces you need to loosen the clamp screw on the underside of the eyepiece
holder. You can then easily remove and replace the eyepieces.
The clamp screws serve only as protection so that the eyepieces will not fall out.
Note:
The LED illumination has a life span of approx. 20,000 hours. In the case of a technical error
please contact the service center.
7. Adjusting the friction of the focusing drive
It can happen that the Microscope head is no longer held by the focusing drive and shuts
down because of his net weight.
By turning the two focusing wheels in opposite directions, the friction can be adjusted more
firmly or loosely.

8. Cleaning and maintenance

Your microscope is a high-quality optical instrument. Please take care that neither dust nor
fingerprints take place on the optical surfaces. If necessary, clean the microscope body with a
slightly moistened soft cloth. Use a separate clean cloth with some drops of alcohol to clean
the optical surfaces. After using, the microscope should be protected with its dust cover.
Note:
Please consider that a sufficient treated microscope keeps its value and optical quality for
many years.
