3.2 Operation of the biological microscope
• Put the specimen on the stage and fix it with the slide clips. Never exam-
ine a prepared specimen without a cover slip. Note: The thickness of the
cover slip must be 0.17 mm.
• The aperture diaphragm of the condenser should be opened to the posi-
tion matching the numerical aperture of the objective.
• For models with a movable condenser, lower or raise the condenser to
locate the best illumination for the field. Start with the condenser all the
way to the top of its range.
• Rotate the brightness control to the desired illumination.
• Always begin examination using the low power objective. Position the ob-
jective as close to the specimen as possible and focus by slowly increas-
ing the distance between the specimen and the objective. Use the coarse
focus adjustment, and then the fine adjustment.
• Once the specimen is in clear view under low power, switch to a higher
power objective and refocus using the FINE FOCUS KNOB ONLY. The
microscope has been set up at the factory so only a small adjustment is
necessary when changing objective lenses.
• Always switch back to the low power objective to change the specimen on
the stage.
