1) until the specimen comes into view. You may need to adjust
the stage movement knobs (Figures 1& 6) slightly to center the
specimen in the field of view. The larger focus knob is the coarse
focus and the smaller knob is for fine (exact) focusing.
6. With the 4x objective lens, you can also vary the power anywhere
from 40x to 160x by using the digital zoom. To use the digital
zoom, touch the screen icons on the right side of the screen to
increase or decrease the power from 1x to 4x.
7. For higher powers, you will need to rotate the objective
nosepiece to the 10x or 20x and to the 40x objective for the
maximum power. You will have to refocus when changing the
power of the objective lenses. While using any of these objective
lenses, you also can increase power by using the digital zoom.
Note that using a higher power objective lens will yield sharper
images than a lower power objective lens and digital zoom for the
same magnification.
8. Your microscope includes a 60x objective lens packed separately. The
60x objective allows you the maximum power available. When specimen
detail requires extreme power, you can install the 60x objective lens by
replacing any existing objective lens. Turn the knurled ring at the top of
the objective lens you want to replace counterclockwise until it comes
out. Then, install the 60x objective lens by turning it clockwise until tight.
NOTE: When changing objective lenses, lower the stage to its lowest position so you do
not hit anything during the rotation. At the higher powers, be careful when raising
the stage close to the objective lens so that the objective does not hit the slide
specimen (or other object) and cause damage.
USING FILTERS & THE DIAPHRAGM
Normally, most viewing or imaging can be done without colored
filters. Before using the microscope, check to make sure no filters are
in the optical path. To bring out different levels of detail, experiment
with changing the color of the back lighting of the specimen
especially for very bright transparent specimens. To change the
lighting color, rotate the wheel (Figure 8) to the desired color – Red
(R), Green (G), Blue (B). Each color is centered when you hear/feel
the faint click stop. You may need to refocus by adjusting the focus
knob (Figure 1) slightly for best viewing. You should experiment with
each of the colors to see what works best.
Wheel
Fig 8
Diaphragm — Within the wheel are holes with three different
diameters, 1 mm, 3 mm, 6 mm that limit the amount of light passing
through to the specimen. These holes are part of the diaphragm.
Changing the hole opening size helps you maximize the contrast,
brightness, etc.
The default setting is for the 6 mm hole, which should be used for
most viewing. You can look under the stage (see Figure 9) to make
sure the proper setting is actually being used.
ROTATING THE LCD SCREEN
You can rotate the viewing position of the LCD screen 180°: 90° to
the right and 90° to the left. You can view any position you choose
along the 180° rotation. This function allows you to share the view
with others without actually moving the complete microscope. To
move the LCD screen, hold the top of the arm (see Figure 1) with
one hand, hold the LCD module with the other, and move it to the
position you desire.
You can adjust the tension of the rotation of the monitor by
tightening/loosening the adjustment screws as shown in Figure 1.
It is best to have the tension somewhat tight so the monitor is rigid.
Turn the LCD screen on and you are now ready to use your
microscope for viewing. If any problems arise, check the
troubleshooting section.
AV/TV CABLE
To view specimens or images on a larger format screen, connect the
AV/TV cable in the receptable (see Figure 1) on one end and the
other end into the socket on the monitor (if your monitor has a socket
for this purpose).
