Assembling
7.1
Installing the objectives
1. Turn the coarse focusing knob ① until the nosepiece
reaches its lowest position.
•
For a safe transport, the nosepiece is placed in the
lowest position and the tension adjustment collar
② is adjusted to the proper tension when the mi-
croscope leaves the factory. (Fig.1)
2. Screw the lowest magnification objective on the nose-
piece from the right side, then turn the nosepiece clock-
wise. Mount the other objectives in the same way, fol-
lowing 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
microscope, cover all the unused holes with dust caps
③. (Fig. 3)
•
When operating, use the low power objective (10X) to
search and focus the specimen, then switch to higher
magnifications.
•
When switching between objectives, slowly turn the
nosepiece until it clicks. The click means that the objec-
tive is in the right position, in the center of the light path.
7.2
Installing stage extension or mechanical stage
•
Stage extension and mechanical stage are optional
accessories for some models.
•
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
of the stage.
1. Installing the units: screw the bolts in the fixing holes
of the attachments, then mount the unit from below the
stage. (Fig. 4)
