2-2-4 Installing the Lamp House
Keep the bolt on the lamp house
(figure 6) in line with the jack on the back of
the microscope (like the show of figure 7),
then pushing the lamp holder into the
illumination kits gently until they are against
each other (figure 8).
2-2-5 Installing the Objective
1. Adjusting the coarse focus knob until the
support device of the mechanical stage reach
its low limit position.
2. Wresting the lowest magnification objective
onto the nosepiece from the left or the right
side (figure 9), then push the nosepiece
clockwise, then place other objectives by the
sequence of low to high magnification ( figure
10).
Installing objective this way will make the
change of magnification to be easier while in
using.
Clean the objective regularly, the objective of
the inversed microscope is very sensitive to
dust.
When operating, use 10

When replacing the objective, slowly
