OBSERVING OPERATION
1.
Press the power switch 10 on the side “I”, which means the circuits
is got through.(Fig.2)
2.
Push the observation/photo lever 5 in the trinocular tube to
observation position. (Fig.3)
3.
Interchange the objective 10X into optical path, with 10X eyepiece
to observe, turn the coarse/fine adjustment knob 5/6 to make the
image clear, pull the field diaphragm adjustment lever 4 to let the
diaphragm smaller, then adjust the field diaphragm adjustment
screw 1 to make the center of the field diaphragm on the optical
center. Pull the diaphragm lever 4 again to let the image of the
diaphragm slightly larger than diaphragm in the field (Fig.3),
Now it’s ready to use.

This microscope is equipped with simple polarization device. Push
the Polarizer lever 3 to make the analyzer into the optical path of
the observation. Push the polarizer 2 into the vertical illuminator
(Fig.3), Rotate the polarizer 2 while watching the brightness in the
field and let the polarizer and analyzer orthogonally, then put the
specimen on the stage and observe with orthogonal polarization
condition.
