Using the microscope

Observation head
Loosen the lock-screw, turn the observation head to a comfortable position for observation, and then lock the
lock-screw.
Place the specimen on the stage
Lock the specimen slide on the mechanical stage using the slide clamp. Ensure that the specimen is centred
over the stage opening by adjusting the coaxial knobs of the stage.
Illumination system settings
The microscope is fitted with a white LED illuminator. Turn the brightness adjustment knob to a brightness
suitable for observation.
Adjust interpupillary distance
Hold the right and left parts of the observation head with both hands
and adjust the interpupillary distance by turning the two parts until
one circle of light can be seen.
The white dot (°) placed on the right eyepiece shows the set
interpupillary distance. Just remember this value to help on later
settings.
Focus tension adjustment
The tension of the coarse focusing knob is preset by factory.
To change the tension according to your preference, just rotate the
knob (3) clockwise in order to increase it.
Excessive tension could damage the mechanism of focus. A too
loosed tension causes the descent of the stage by gravity or a
sudden loss of focus. In this case, rotate the knob (3) to increase
the tension.
Diopter adjustment
Turn the dioptric adjustment ring on the left eyepiece halfway. Turn
the coarse focus knob in order to focus the slide with an objective
with low magnification. Adjust the fine focus knob until you obtain
a clear and defined picture observing with the right eye, and then repeat the operation with the left dioptric compensation ring and the
left eye. When the image appears in focus, choose the necessary
objective with the revolving nosepiece.
