1. General/Location
Before starting to set up your microscope, select a suitable location for it. First make sure
that your microscope is put up on a stable, vibration-free basis. Take care for a sufficient
brightness at your oberving location.
2. Observation
Place the object to be viewed in the centre of the microscope stage (8). If it is possible,
clamp it on the edges with the object clips (9). Now, look through the eyepieces of the
binocular viewing (3) and change the spacing between the eyepieces (1) so that you get a
round, clear field of view. The definition is adjusted by slowly turning the focussing wheel
(6). If you have to observe a very large or very small object, you can adjust the microscope.
Loosen the holding screw on the back and move appropriately the microscope head on
its guidance (7). If you have found the correct position, tighten the holding screw again.
3. Diopter adjustment
Turn the diopter adjustment ring (2) of the right eyepiece to the middle position (silver
marking ring). Shut your right eye and look with the left eye through the left eyepiece.
With the focussing wheel (6), focus correctly for your left eye. Now, look with your right
eye through the right eyepiece. If the image isn't sharp, adjust the focus for your right eye
by turning the diopter adjustment ring (2). Now, the microscope is correctly adjusted.
4. Care and maintenance
Cleaning the lenses: Sweep the lens with a lens tissue or soft fabric immersed with a
small amount of alcohol (e.g. isopropanol).
Cleaning the painted parts: The dust on the painted parts can be removed by gauze.
For the grease spots, the gauze immersed slightly with aviation gasoline is recommended.
Do not use organic solvents such as alcohol, ether ot other thinner etc. for cleaning the
painted parts or plastic components.
Your microscope is a high-quality optical instrument. Avoid disassembling the
microscope. Improper disassembling affects the high utility of the microscope. Moreover,
the warranty expires.Cover the microscope with the dust protective cover and place
it there, where it is dry and dust-free. We suggest the storage of all objectives and
eyepieces in a closed container with drying agent.
