Detailed explanation-1: -4. COARSE ADJUSTMENT KNOB-A rapid control which allows for quick focusing by moving the objective lens or stage up and down. It is used for initial focusing.
Detailed explanation-2: -The coarse adjustment knob quickly brings the image into focus, and the fine adjustment knobs help maintain focus as the magnification increases.
Detailed explanation-3: -Use the fine adjustment knob to locate your specimen if possible. Don’t worry if you cannot and then have to start over. This is the point where most people, if they will have to begin again, will have to do it. Sometimes scientists who are very good at using microscopes have to start over at this point.
Detailed explanation-4: -Use the focus knob (4) to place the sample into focus and readjust the condenser (7) and light intensity for the clearest image (with low power objectives you might need to reduce the light intensity or shut the condenser).
