Installing the objectives
Turn the coarse focusing knob ① until the nosepiece rea-
1.
ches its lowest position.
•
For a safe transport, the nosepiece is placed in the lowest
position and the tension adjustment collar ② is adjust-
ed to the proper tension when the microscope leaves the
factory. (Fig.1)
2. Screw the lowest magnification objective on the nosepiece
from the right side, then turn the nosepiece clockwise.
Mount the other objectives in the same way, following the
sequence from low to high.
•
Note: the objectives can also be installed through the
stage opening. (Fig. 2)
•
Clean the objectives regularly. In inverted microscopes, the
objectives are very sensitive to dust.
•
To prevent dust and contamination from entering the mi-
croscope, cover all the unused holes with dust caps ③. (Fig.
3)
•
When operating, use a low power objective to search and
focus the specimen, then switch to higher magnifications.
•
When switching between objectives, slowly turn the nose-
piece until it clicks. The click means that the objective is in
the right position, in the center of the light path.
Installing stage extension and mechanical stage
•
Stage extension and mechanical stage are optional ac-
cessories.
•
Stage extension can be installed on either side of the stage
to enlarge the working surface.
•
Mechanical stage can only be installed on the right side.
1.
Installing the units: screw the bolts in the fixing holes of the
stage, then mount the unit from below the stage. (Fig. 4)
•
NOTE: The stage has a series of holes in the underside.
To install the mechanical stage it is necessary, starting
counting from the front of the microscope, to use the third
and fifth holes. By using a different set of holes, the me-
chanical stage will not be installed correctly.
