3.1 Adjusting illumination
1) Insert the power cord into the power socket on the microscope and connect it to the
power outlet.
2) Turn on the main switch at the back of the microscope. 3) Rotate the intensity dial to
increase or decrease the brightness.
3.2 Placing specimen
1) Place the slide on the mechanical stage.
2) Use the slide holder to gently secure the slide.
3) Turn the X and Y translation knobs to position the specimen for viewing.
Caution:
Be sure not to allow an objective to touch a specimen slide when changing
objectives.
3.3 Focusing
1) With the 10X objective in position, raise the mechanical
stage using the coarse focus knob until the specimen is
close to the objective.
2) Turn the coarse focus knob until the specimen is in focus.
Then use the fine focus knob to obtain a sharp image. You
may now switch to another magnification objective.
Tips:
T
o prevent your specimen slide from making contact
with an objective, turn the 100X objective in position and
rotate the focus stop lever clock-wise all the way to the
end so that the 100X objective will not contact the
specimen while the stage is adjusted to its highest
position.
3.4 Adjusting interpupillary distance
While observing with both eyes, hold the left and right eyepiece tubes then swing them
around the center axis. The interpupillary distance is correct when the left and right fields
of view converge completely into one image.
3.5 Adjusting eyepiece diopter
1) Using the 10x objective and your left eye only, observe your specimen through the
eyepiece and bring it into focus by adjusting the focus
knobs.
2) Then observe the specimen with your right eye only
through the right eyepiece. If the specimen is not in focus,
turn the diopter ring on the eyepiece tube until a sharp
image is obtained.
3.6 Adjusting condenser
1) Turn the condenser focus knob to raise or lower the
condenser.
2) The condenser is raised when using high magnification
objectives and lowered when using low magnification
objectives.
Note:
The centering of the condenser and the light axis of the objective are factory adjusted.
