The Coarse adjustment knob
The coarse adjustment knob allows quick displacement of the optical tube.
the big knob is called the coarse adjustment knob and the smaller one is the fine adjustment knob coarse does a large scale focus, fine does such small scale focus you can only see a difference in how the (item under microscope) looks. You don't see the stage / nosepeice move up or down.
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.

The function of the coarse adjustment knob on a microscope is to lower or raise the stage of the microscope. This mechanism is used to focus the specimen.
The Coarse adjustment knob
The coarse adjustment knob is a component of a microscope. It is used to lower or raise the stage of the microscope in order to focus the specimen.
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.
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.
There are two adjustment knobs (coarse and fine) on a microscope so you can move the stage at two different speeds. The coarse moves a lot per revolution, while the fine adjustment knob moves the stage at such small increments that it is nearly impossible to notice when looking from the side. The coarse adjustment knob should be used to get the stage closer to the lens only while you are looking at the microscope from the side. The fine adjustment knob can be used when you are looking into the microscope because there is a much lower chance of running the stage into the lens and breaking it.
I assume you would use the fine adjustment knob for high power objectives.
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.
