Maintenance - Gima 31001 Use And Maintenance Book

While turning the nosepiece, pay attention that the specimen does not hit the objectives!
The lenses and the specimen can be damaged!
ADJUSTMENT
1. Interpupiliary adjustment
Place the specimen on the plate and precisely focus it. Adjust the interpupiliary distance until the two
views on the right and the left become one.
2. Adjusting the diopter
Position the specimen on the stage. Move the lens in operating position. First look with left eye in left
eyepiece and focus with knobs until the image is clear. The look with right eye in right eyepiece and
adjust until image is clear.
3. Coarse and fine adjustment
The instrument uses a coaxial focusing mechanism. The tension ring on the right of the microscope
near the focusing knob is used to adjust the tension of the coarse adjustment knob
table to drop due to gravity. Use the supplied lever wrench to adjust. The knob lock
prevent the specimen and the lens from touching. The outer knobs are used for fine adjustment operations
During focusing operations make sure the specimen never touches the lens!
4. Tray
The practical specimen holder
used to move the stage on the horizontal surface.
5. Mobile condenser
The condenser can be lifted or lowered by rotating the condenser adjustment knob
can be easily removed by removing the condenser fastening screws

filter housing under the condenser's diaphragm.
6. Main switch and brightness adjustment
Switch on the main switch
clearest possible image.
Do not leave the speed wheel at maximum setting too long. This will reduce the technical
life of the lamp.
7. Adjusting diaphragm field
Switch on the device, position the sample on the stage, set lens in operating position, look through eyepieces.
Rotate the knob to adjust the height of the condenser to obtain the image of the diaphragm field.
8. Diaphragm aperture
The diaphragm aperture lever
By adjusting the aperture of the diaphragm you can obtain an image with a good contrast.
Usually by adjusting the aperture diameter of the image of the diaphragm at 70-80% of the lens you
can reach a good result. As a general rule, a large aperture means the image has a higher resolution and
brightness, a small aperture means the depth of field and the contrast are bigger.
The microscope GIMA is a precision optical instrument and must be handled with great care:
- Place the microscope in dry and clean environment, avoiding sudden changes in temperature.
- When the microscope is not used, always protect it with a dust-proof cover. If you think you do not
use it for a long time, replace it into the apposite case supplied with the microscope. For the best
