The course adjustment moves the stage of the microscope further/closer away from the objective lens (it is used for general focusing), and the fine adjustment moves the objective lens very small distances for finer focusing.

This is the coarse adjustment knob. This should be used before the fine adjustment knob (the smaller knob) - which is for fine focusing.
use the fine adjustment knob to get a better view of what you are looking at.For low power you can use the coarse adjustment and fine adjustmentfor high power you should only use the fine adjustment because on high power, the objective lens is too close to the slide and using the coarse adjustment may scratch the objective lens.
Use a coarse adjustment knob (large movement) to get near, then use the fine adjustment knob (small movement) to fine-tune.
When the "fine" adjustment control does not bring operation into the desired range.

The function of a microscope's coarse adjustment knob is to improve focus on the object under study by adjusting the lens. Unlike the fine adjustment, coarse adjustment moves the lenses quickly.
The adjustment knob that moves the body tube for focusing with the high-power objective lens is called the fine focus adjustment knob. It allows for precise adjustments to bring the specimen into sharp focus at high magnifications.
First of all, one should never call it high power, it is morecommonly called the "high objective", yet that is not what this question is asking. To answer the question: You use the fine adjustment knob. This knob should be located near the coarse adjustment knob, on the opposite side of the microscope (at the same height as the coarse adjustment knob), or even as a separate knob protruding from the coarse adjustment knob. The fine adjustment knob is smaller in size. You should never, ever use the coarse adjustment knob under the high objective, you could scratch the microscope slide, cover slip, high objective lens, or in a worst case scenario break the high objective lens.
On a What_is_the_function_for_the_course_adjustment_knob, the coarse adjustment knob moves the tube or stage up or down to bring the object into focus ,you have to use it when an object is not in focus.
The coarse adjustment knob elevates the microscope's stage up and down quickly. The fine adjustment knob does the same thing but more slowly and accurately. In other words, the fine adjustment knob should require more revolutions to elevate the stage as much as the coarse adj. knob does.
It is used for focusing.
The adjustment knob is a component of a microscope that focuses the image of the object being studied. It is used in conjunction with the coarse adjustment knob.
