6
approximately 2mm from the objective. Slowly turn the coarse
focusing knob until a clear image is obtained, then use the fine
focusing knob to enhance the observation of the specimen to it’s
clearest image. If the magnification is increased, here you can
obtain clear image under other higher magnification objectives
with a little fine adjustment.
7.
When using objective 100x to observe, lift the condenser to the
highest position, then drop a little cedar oil on surface of objective
100x and specimen (cover slip). If there’s air bulb in oil, it will
influence observation. Take out air bulb by swinging nosepiece
several times. The 100x oil immersion objective and specimen
should be wiped off with a piece of soft clean cloth or lens tissue to
remove the cedar oil with xylene immediately after using.
8. If you find to lift the mechanical stage too tension or loosen in use.
Turn the tension adjusting ring. Coarse focusing knob would be
tightening if it turns in the clockwise direction, on the other hand it
would be loosen.
9. You may lock up the focusing stopper in the other side of the
microscope, when you see the image of the specimen clearly.
Then the mechanical stage only to be able to rise and fall below
the focusing position. When you do not the location, you can turn
the flange of the focusing stopper and loose it.
10.
Turn transversal and longitudinal direction adjustable knobs
located just below the stage, the specimen may be moved to the
center of the eyepiece’s viewing field for observation.
11. Turn coarse & fine focusing knob to focus the specimen till you
see clear image of specimen when observing the fixed eyepiece
with eye. Then rotate the diopter adjusting ring, if the image is
unclear when observing the another eyepiece with another eye,
also still you see clear image of specimen (Remember your eye’s
diopter, so that you could use next time). When using two eyes to
observe, hold the base of the prism and rotate them around the
axis until there is only one field of view.
12. Remove dustcover when useding the trinocular head, the CMOS
electronic eyepiece, Photo and CCD attachment put conveniently
into the trinocular tube. You may be ready to begin working after
shift the light path by moving the light path shifting rod into the
working position.
13. LED replacement: Loosen the knurled screw on the underside of
microscope and open the panel to expose the bulb. Remove the
old LED after it becomes cool. (The LED will become very hot
when using or after using.) Don’t touch the new LED with finger.
14. Fuse replacement: Open the fuse holder with a screwdriver in the
back of the microscope. Remove the old fuse and install a new
fuse with the same specification. Replace fuse holder in place.
