Installing the objectives

1. Turning the coarse focusing knob
nosepiece reaches its lowest position.
► For a safe transport, the nosepiece is
placed in the lowest position and the
tension adjustment collar
ed to the appropriate tension when the
microscope leaves the factory. (Fig.3)
2. Screw the lowest magnification objective
on to the turret from the right side, then
turn the turret clockwise. Mount the other
objectives in the same way, following the
sequence from low to high.
► Note: the objectives can also be in-
stalled through the stage opening.
(Fig.4)
► Clean the objectives regularly. In inverted
microscopes, the objectives are very sen-
sitive to dust.
► To prevent dust and contamination from
entering the microscope, cover all the un-
used holes with dust caps
► When operating, use the low magnification
objective (10X) to search and focus the
specimen, then switch to higher magnifica-
tions.
► When switching between objectives, slowly
turn the nosepiece until it clicks. The click
means that the objective is in the right posi-
tion, in the center of the light path.
