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.
Coarse adjustment of what?
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.

Coarse adjustment in a microscope is used to quickly focus on the specimen by moving the stage or objective lens up or down in large increments. This adjustment is used to bring the specimen into view before using the fine adjustment for finer focusing details.
The coarse adjustment is used to focus in on the specimen. It accomplishes this by moving the stage or the upper part of the microscope.
It sets or adjusts the coarse of a speciment in a microscope.
Use a coarse adjustment knob (large movement) to get near, then use the fine adjustment knob (small movement) to fine-tune.
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.
