Instruction

1
Establish a microscope before yourself on a reliable support, for example, on a table. The device has to settle down slightly on the left from you, in several centimeters from the table edge. Having established a microscope into place, try not to shift it before the end of supervision.

2
If the device has illumination, evenly guide it at the studied object and adjust. Muffle too bright light, using for this purpose filters of blue or green color.

3
Before using the device, check its settings and correct them if necessary. For control of a microscope draw a small dagger on a clean sheet of paper. Place a leaf on a subject little table that the cross settled down in the middle of a field of vision.

4
Look in a microscope one eye. Now close an eye and look at a dagger another. If the cross remained in a midfield of sight, settings are exposed correctly. If when examining a dagger the second eye it looks displaced, adjust the device the corresponding screws.

5
If you use a binocular microscope, adjust also depth of sight and distance between eyes, having arranged them under the specific features.

6
In advance prepare all materials for research, they have to be near at hand, near a subject little table, but not disturb supervision. Place the object interesting you on a subject little table and start researches.

7
Considering object of supervision in a microscope, accept the correct pose. It is desirable to sit not movably, in the same situation. Elbows have to concern a table. Previously pick up a chair so that it was convenient; adjust it on height if it allows a design.

8
Do not work behind a microscope more than fifteen minutes in a row. Otherwise it is possible to get short-sightedness. After short examining of object make a pause, having filled it with gymnastics for eyes (move eyes in different directions, up and down, blink). Look in a window at remote object, and then for a couple of minutes cover eyes with palms.
