OPERATION
1.
Illumination (only for models with built in illumination)
a. Before operating the microscope, adjust the intensity controls located on each side of the
base to the minimum position. This should be done prior to each time light is turned on or
off. Failure to do so will significantly shorten the life of the bulb.
b.
Make certain that the main voltage of your microscope corresponds to the voltage of your
power outlet, either 120v or 220v. Insert microscope power cord into power outlet.
c.
The S6 on lighted LED stand includes a glass stage plate. This plate is ideal for viewing
transparent specimen slides or specimens that are thin enough for light to pass through
them (insect wings, plant leaves, etc.). Alternate black/white contrast plates can be used
when viewing opaque objects or for dissecting.
d.
Some models come equipped with a rocker switch on the base of the microscope. These
switches are used to turn the light on/off. The rheostat control knobs will not work if the
rocker switch is in the “off” position.
2. Interpupillary Adjustment
This will permit each user to adjust the spacing between
eyepieces to accommodate distance between their eyes.
While looking through the microscope eyepieces with both
eyes, grasp eyepiece tube housings with both hands and rotate
them, moving eyepieces apart or together until a full field of
view is observed and the images blend into one. Interpupillary
distance is now corrected for your own inter-ocular distance
and does not require further adjustment unless another user
changes the adjustment.
3. Focusing
a.
Adjust zoom control knobs (located on both sides of the
head) so that the lowest magnification number “0.7”
is positioned at the white notch index on head. Lower
magnifications have larger fields of view, making it
easier to position and locate area to be viewed.
b. Place object on stage.
c.
Position focusing knobs in the center of focusing range.
d.
Use included allen key to lock and set magnification if
desired.
