PROPER USE OF THE MICROSCOPE 1. When moving the microscope, always carry it with both hands (Figure 1). Grasp the arm with one hand and place the other hand under the base for support. 2. Turn the revolving nosepiece so that the lowest power objective l ens is "clicked" into position...
How to Use the Microscope: 1.Plug in the lamp. 2.Place a specimen on a slide. 3.Adjust the mirror so it reflects light from the room up into the objective lens. 4.Place your slide with the specimen directly over the center of the glass circle on the stage.If it is a wet slide,...
