Adjustment and operation of the stereomicroscope
Stereomicroscope in the use of the adjustment before the main focus, visual adjustment, pupil distance adjustment and bulb replacement steps. They are explained below.
Focusing: Place the table plate into the mounting holes of the table plate on the base. Observation of transparent specimens, the choice of hairy glass plate; observation of opaque specimens, the choice of black and white plate. Then loosen the focusing slide on the fastening screws, adjust the height of the mirror body, so that its magnification with the selected objective lens roughly the same working distance. After adjusting, the fastening screw must be locked. When focusing, it is recommended to use flat objects, such as flat paper with characters printed on it, straightedge, triangular board, etc.
Degree of vision adjustment: first of all, the right and left eyepiece barrel on the degree of vision circle are adjusted to the 0 mark position. Usually, the first observation from the right eyepiece barrel. Turn the zoom handwheel to * low times the position, turn the focusing handwheel and the degree of vision adjustment circle on the specimen to adjust until the specimen's image is clear, and then turn the zoom handwheel to * high times the position of the specimen to continue to adjust until the specimen's image is clear, at this time, with the left eyepiece barrel to observe, such as unclear along the axial adjustment of the left eyepiece barrel on the degree of vision circle, until the specimen's image is clear.
Pupil distance adjustment: Trigger the two eyepiece barrels, you can change the pupil distance of the two eyepiece barrels. When the user observes the two circular fields of view in the field of view completely overlap, it means that the pupil distance has been adjusted. It should be noted that due to individual vision and eye adjustment differences, therefore, different users or even the same user at different times when using the same microscope, should be adjusted separately for focusing, in order to obtain * the best observation effect.
Lamp Replacement: Whether you are replacing the upper light source bulb or the lower light source bulb, be sure to turn the power switch off and unplug the power cord from the power outlet before replacement. When replacing the upper light source bulb, first unscrew the knurled screw of the upper light source light box, remove the light box, then remove the bad bulb from the lamp holder, replace it with a good bulb, and then install the light box and knurled screw. When replacing the lower light source bulb, you need to remove the glass table plate or black and white table plate, from the base, and then remove the bad bulb from the lamp holder, replace it with a good bulb; and then install the glass table plate or black and white table plate can be. When replacing the bulb, please use a clean soft cloth or cotton gauze to wipe the bulb glass shell clean to ensure the lighting effect.
