5.2 Operation of the control panel
Turn on Main power switch (10), the indicator lights; the instrument enters state of working
preparation. Turn on power for light source and let the cooling fan start., push the left
Brightness regulative button (11)
on the panel, the brightness of cold light source increases
step by step. According to the brightness requirement of the operation doctor, regulate light
brightness.
Oblique illumination and coaxial illumination can be used at the same time.
5.3 Operation of the frame
Loosen the locking knob (5), (18), (20) and (23), the head should be roughly arranged in the
scope of vision based on the distance and height of the patient. After coarse adjustment, it is
necessary to fix all the locking knob.
Through electric focusing mechanics, distinct image can be seen. Till this process, the
microscope is ready for operation.
5.4
Operation of the microscope head
The operation of microscope with steeples zooming system is different from step focusing
microscope. Before operation, the operator should do as follows: First, adjust eyepieces’
diopter according to the operator’s diopter, and then set the microscope in highest
magnification location, with left eye or right eye observe the picture in the optical path and
adjust focal length electrically to make picture more clear, then, put it in lowest magnification
location. If picture is not clear now, adjust eyepiece until the picture become clear. Repeat such
operation 2~3 times till images at high and low magnifications become distinct. Then, regulate
the other eyepiece as the same way. At this time the operator should remember the diopter of
two eyepieces of this location. For next operation the operator should only adjust the diopter to
that location and need not repeat the above-mentioned processes.
5.5 After operation
Turn down the brightness to the lowest location by push the right Brightness
regulative button (11) on the control panel step by step;
Operate the Foot controller (1), be sure that the head back to the middle location;
Power off;
Turn back the covers of big objective lens and eyepieces and fold the instrument
frame back, and cover the dustproof coat.
5.6 Replacing the bittern tungsten lamps
There is a spare cold light source in the translation arm. If bittern tungsten lamp is burnt out
suddenly in operation, you can pull out this lamp immediately together with lamp frame from
the top of transversal arm, pull out the spare cold light source and insert it into the location of
the lamp frame to be changed. Continuous operation will begin if turning on the lamp.
As shown in Fig.17, when changing the lamp, it is necessary to take down the socket for
bittern tungsten lamp first and then put a good lamp 12V/100W into the location already
empted, connect the power socket and put the lamp frame into the spare part location. The
operator should always keep the spare lamp good.
Notice: The lamp that just burnt out should not be changed at once, in order to
avoid injuring for hot.
