ASSEMBLY
1. Remove microscope from Styrofoam packing and place it on a stable
worktable. Remove all plastic bags and paper covering (these can be
discarded).
2. Connect cord to power supply and your microscope is ready for use.
OPERATION
1. Make sure the 4x objective lens is in position for use. This will make it easier to
put your slide in place as well as to position the item you wish to look at. (You start
at low magnification and work up.) Put a slide on the stage and clamp it carefully
with the moveable spring clip.
2. Connect the power and turn on the switch.
3. Always begin with the 4x objective. Turn the coarse focus knob until a clear
image is obtained, then use the fine focus knob to enhance the observation of
the specimen to its clearest image. When the desired view is obtained under the
lowest power (4x), rotate the nosepiece to the next magnification level (10x).
The nosepiece should “click” into position. Adjust the focusing knobs as needed
to once again find a clear view of the specimen.
4. Turn the coarse adjustment (large) knob, observing the image of the specimen
through the eyepiece. Use the fine adjustment (small) knob for more clarity.
5. The iris diaphragm below the stage can be opened (slide lever forward) or
closed (slide lever back to left) to control the amount of light directed through the
condenser. The condenser assembly under the stage can be shifted up or down
by means of the control knob (left hand side under stage) to effectively move the
light beam closer to (up) or away from (down) the specimen under observation.
Try experimenting with various settings to get the most effective view of your
specimen.
6. It is important to remember when adjusting the focus that the objective should
never touch the specimen. When increasing to OPTIONAL 100x objective, the
objective will appear to be very close to the slide. Because the 100x is an oil
immersion objective, a drop of cedar-wood oil or other immersion oil should be
applied in the gap between the objective and the specimen. (Note: All slides
should be prepared with cover slips over the specimen for observation under the
100x objective.) The 100x oil immersion objective should be wiped off with a
piece of soft clean cloth or lens tissue to remove the immersion oil immediately
after using. It is strongly recommended if requesting the 100x objective to also
purchase the mechanical stage option.
