OPERATION
1.
Illumination (only for S-6.6-BLED & S-6.6-TD-LED Models)
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 signifcantly shorted 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 S-6.6-BLED & S-6.6-TD-LED Models are furnished with two stage plates (the S-6.6-BL
and S-6.6-TPD Models are furnished with one B/W). The frosted stage plate can be used
when viewing transparent specimen slides or for viewing specimen that are thin enough
for light to pass through (insect wings, plant leaves, etc.) The plastic black/white contrast
plate can be used when viewing opaque objects or for dissecting. Choose side of plate
providing best contrast with specimen.
D.
For models S-6.6-BLED & S-6.6-TD-LED, there are two rocker switches on either side of the
base of the microscope.
Left side = Turns incidental light on (top illumination)
Right side = Turns transmitted light on (substage illumination)
To remove stage plate: Loosen locking set screw on front of base but unscrewing to the
left.
2.
Interpupillary Adjustment
This will permit each user to adjust the spacing between eyepieces in order 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 later 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 plate.
