(
Fig.1
)
1) Loosen the set screw on the top of the microscope
body and remove the plastic cover.
2) Remove the cap on the dovetail of the trinocular
viewing head.
3) Seat the dovetail of trinocular viewing head into the
socket on the top of microscope body completely and
tighten the set screw.
Caution
:
Do not release the viewing head from your hand grip until you are sure the viewing
head is installed securely.
2.2 Installation of the photo tube
1) Remove the cap on the top of the viewing head.
2) Thread the photo tube into the top of the viewing head.
2.3 Installation of the eyepieces
1) Remove the protective caps from the eyepiece tubes.
2) Insert the eyepieces into the eyepiece tubes.
2.4 Installation of the objectives
1) Adjust the coarse focus knob until the mechanical stage is at its lowest position.
2) Turn the caps counter-clockwise to remove them from the nosepiece.
3) Take the objectives out from the plastic cases and turn each one clock-wise into the
holes on the nosepiece. Install the 4X objective into the nosepiece first. Then in a
counter-clockwise direction, rotate the nosepiece and install each succeeding higher
magnification objective as shown in
Fig. 2
.
Note:
Inspect the objectives frequently for dirt or oil; clean if necessary.
Use the 10X objective to initially focus the image of your specimen.
When changing the objective magnification, rotate the objective nosepiece until
you hear a “click” sound or have a clear “in position” feeling. This ensures the
objective is centered in the optical light path.
