article : Know the General Rules for Using the Microscope

1. Use light from a microscope lamp unless microscope has internal illumination.
   
   
2. Adjust the condensor so that it is flush with, but not above, the stage.
   
   
3. Place the specimen to be observed directly over the lens of the condensor.
   
   
4. Focus first with low power. Bring down the objective to its lowest point (without touching the slide) and observe the slide as the objective is raised by rotating the course adjustment knob in a counter-clockwise direction.
