V. OPERATION
1. Plug in power
；
2. When use the model STMPRO with transmitted illumination (Fig.1), you should turn on the power switch 24 at first,
then turn on the transmitted light brightness adjusting knob 17, which means the transmitted light working. When
use it with reflected illumination, you should plug the Reflection illumination power plug 6 and turn on the reflected
light brightness adjusting knob 20, which means the reflected light working, and then adjust the angle and
brightness of reflected illumination to satisfy your needs. When use it with mixed illumination, you should turn on the
both light brightness adjusting knob and adjust their brightness to obtain satisfactory mixed illumination
；
3. If you want to change the position of observation, you can loose the tube of holding screw 21, then turn the binocular
or trinocular in any angle which you need, then tighten the screw 21 again
；
4. Turn the both diopter ring 3 to “0” and zoom knob 10 to 4.2X, observe with your right eye and turn the focus
adjustment knob 13 to make the image of specimen clear, then observe with your left eye and adjust it’s diopter, no
adjusting focus adjustment knob 13, to make the image of specimen clear
；
5. Turn the zoom knob 10 from 4.2X to 0.7X, if the image isn’t clear, you should observe the left and right eyepiece tube
with respective eye and adjust respective diopter to make image clear, then turn the zoom knob 10 to 4.2X again, if
the image isn’t clear , you should adjust the focus adjustment knob 13 to make the image clear. According to the
adjustment above, you can obtain a clear and continue image from 4.2X to 0.7x
；
6. Observes the image with both eyes, adjust the interpupillary distance of the eyepiece tube 4 until the both field of view
can be superposition
；
7. When use the trinocular, you can connect the CCD camera to trinocular with CCD adapter 9. You should Observe
with both eyepieces and adjust according of “
the operation 4 and 5”
until the image clear, then you can observe the
monitor, if the monitor image isn’t clear, you should adjust the CCD adjusting tube 8 to make the image clear. If the
image position on the monitor can’t satisfy you need, you should loose the CCD adapter holding screw and turn CCD
adapter 9 to change the angle of image on the monitor to satisfy your need, then tighten the holding screw again
；
8. If you need the accessorial big objective, you can turn it into objective hood 11
；
9. If you need the annular fluorescence illumination, you can connect it to objective hood 11 with holding screw.
VI. EXCHANGE THE LAMP
1. Reflected illumination: unplug the power supply and turn off the power switch, loosen off lamp cover, pull out the bad
lamp and then install a new lamp, tighten the lamp cover again
；
(Fig.1)
2. Transmitted illumination: remove Organic glass stage, pull out the bad lamp, then install a new lamp again
；
3. Annular fluorescence illumination: loose the annular fluorescence illumination holding screw and take off the bad and
install a new, tighten the screw again.
VII. MAINTENANCE
1. Sweep the lens
Sweep the lens by lens tissue or soft fabric immersed with mixed liquid of alcohol/ether or diethyl benzene. Cleaning
the oil on the 100X objective whenever finish operating.
2
．
Clean the painted parts
The dust on the painted parts can be removed by gauze, for the grease spots, the gauze immersed slightly with
aviation gasoline is recommended. Do not use organic solvents such as alcohol, ether or other thinner etc, for cleaning
the pointed parts or plastic components.
3. Avoid disassembling the microscope
Being a precise instrument, do not disassemble the microscope casually that may cause serious damage to its
performance.
4. Being not used
Cover the microscope with polymethyl methacrylate or polyethylene and places where there is dry and modules.
Suggest that storage all objectives and eyepieces in closed container with drying agent.
