CHAPTER 3. OPERATION:-
Once you have set up your microscope for use, follow the steps below to prepare the specimen to be studied for
viewing:-
Place the slide to be viewed onto the stage so that the stage clips hold it firmly in place.
Position the slide so that the portion of the specimen that you wish to observe is below the 4X objective.
Slowly rotate the coarse focus knob until the stage is approximately 1/8" from the objective, make sure not to let
the slide come in contact with the objective, to avoid damage to the eight or both which may occur.
When using the coarse focus knob, start with the objective as close to the stage as possible and focus from the
bottom up. This will help you to prevent any contact between the objective and the stage.
Adjust the iris diaphragm attached to the condenser to control the angle of light illumination on the specimen.
To change the magnification, first draw the objective to the position furthest from the stage. Then turn the
objective turret until the desired objective is in place. Return the objective to the point closest to the stage and
focus once again backing away from the stage.
To determine the total magnification, multiply the magnification of the objective with that of the eyepiece. (e.g.,
10X objective X 10X eyepiece = 100X magnification).
When using the objective
100X to observe, lift condenser to the highest position, then drop a little cedar oil on
the surface of 100X objective and slide, so as to keep full of cedar oil between the objective and the slide.(clear
the cedar oil with
xylene after observing).
CHAPTER 4. MAINTENANCE:-
Keep the instrument in dry and cool place and keep it away from acid or alkali.
Put the dust cover over it, when not used.
Keep lenses clean, remove the dust by soft brush.
