Installing the Objective
1.
Adjust the coarse focus knob until the
support device of the mechanical stage
reaches its lowest limit position.
2.
Reset the lowest magnification objective
onto the nosepiece from the left or the
right side (figure 9), then push the
nosepiece clockwise. Place the other
objectives assembling the lowest
magnification first and the highest last
(figure 10). Assembling the objectives in
this order will make switching between
objectives easier.
* Clean the objectives regularly, the objectives are
very sensitive to dust.
During operation, use the x10 magnification
objective for the initial focus and observation,
and then use a higher objective for more involved
tasks like dissection.
When replacing the objective, slowly turn the
nosepiece until you hear it click, this means the
objective is now secured in the correct position -
the light path centre.
