with tools, they need only to be “finger tight”. With all four objectives mounted in the nosepiece the entire nose
-
piece can be rotated by hand. As you rotate the nosepiece you will notice that each objective lens has a “click
stop” which stops and holds the objective lens being used in its proper position relative to the optical axis of the
microscope.
3. ILLUMINATION
In order to provide illumination for your new microscope, simple plug the power cord into an electrical socket
and switch your microscope “ON”, and you are ready to begin working.
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, being sure not to
let the slide come in contact with the objective, for damage to either or both 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 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 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).

1. Keep the instrument in dry and cool place, and keep it away from acid or alkali.
2. Put the dust cover over it when it is not used.
3. Keep lenses clean, dust on it is moved with soft brush.
