4.Operation
4-1 Use of glass work board
(1)You can lift the work board directly from the recess with your fingertips(Figure 1).
4-2 Adjustment of the tightness of the focusing mechanism
(1) To adjust the tightness of the focusing mechanism, you can hold one of the handwheels with your hand and
rotate the other handwheel. The tightness depends on the direction of rotation of the handwheel; tighten it
clockwise and loosen it counterclockwise (see Figure 2).
(2) Adjusting the tightness of the focusing mechanism properly can prevent the microscope from sliding down
with the bracket during the observation of the microscope body, and also make Focusing more comfortable.
4-3 Specimen placement
(1) Place the specimen in the middle of the glass work plate, and if necessary, press the specimen with a press
sheet.
(2) Use the illuminator to illuminate the specimen.
4-4 Diopter adjustment and focus
(1) Rotate the zoom handwheel to the maximum magnification.
(2) Rotate the diopter adjustment ring to the 0 mark position.
(3) Observe through the eyepiece on the right. If the image is not clear, turn the focusing handwheel to make
the specimen image clear.
(4) Rotate the zoom handwheel to the minimum magnification.
(5) Observe through the eyepiece on the right, if the image is not clear, rotate the right diopter adjustment ring
②
to make the specimen clear (Figure 3)
(6)Then rotate the zoom handwheel to the maximum magnification. Observe through the eyepiece on the right,
if the image is not clear, repeat the above 3 to 5 steps, which can make the diopter adjustment more precise.
(7) Rotate the zoom handwheel to the minimum magnification. Observe through the left eyepiece, if the image
is not clear, rotate the left diopter adjustment ring
①
to make the imageClear (Figure 3).
4-5 Adjustment of interpupillary distance
(8) Hold the left and right prism boxes with your hands, and turn the left and right prism boxes in the direction
shown by the arrows in (Figure 4)
until the binocular observation is comfortable.
4-6 Use of eyepiece cover
(1) For people who do not wear glasses, hold the diopter adjustment ring with your hands so that it does not
rotate. By rotating the eyepiece, the eyepiece cover can fit the observer's eye better.
(2) For people who wear glasses, the eyepiece cover can be removed for observation.
4-7 Installing and removing the reticle
(1) Unscrew the pressure ring from the eyepiece (as shown in the figure).
(2) Clean the reticle
①
. Place the engraved side of the reticle facing down and fit it into the press ring (Figure 5).
(3) Screw the pressure ring
②
with the reticle into the eyepiece until it is tightened.
(4) To remove the reticle, unscrew the pressing ring
③
from the eyepiece,Take out the reticle,
wrap it in clean paper, and store it.
4-8 Installation of luminaire
Insert the boss of the illuminator assembly into the ring LED bracket facing the objective lens,
and then tighten the screws (as shown in Figure 6).
4-9 Choose light path
(1) Use the lever to move inward and outward to switch between binocular observation and
photography. Move the lever outwards for photography and video (When selecting photography
and recording, visual inspection can also be carried out at the same time); conversely, move the lever
inwards for binocular observation.
No matter which light path is selected, the lever must be moved to the end (Figure 7).
4-10 Assemble photographic tube and photographic eyepiece
(1) Unscrew the dust cover and screw in the camera connector department.
(2) Insert the photographic eyepiece into the tee eyepiece holder.
(3) Put the camera tube on the tee eyepiece holder; then tighten the locking screw (Figure 8).
4-11 Adjusting the brightness of the transmitted illumination of the base
(1) Rotate the brightness adjustment knob as
shown by the icon
①
on the base Button, turn clockwise, the brightness will increase; otherwise, the brightness
will decrease (Figure 9)
