The course adjustment knob raises and lowers the stage of the microscope. This knob is mainly used on the scanning and low power knob to simply find the specimen. When trying to focus directly, use the fine adjustment knob.
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 course adjustment knob on a microscope is used to quickly focus on the specimen by moving the objective lens up or down. It is typically used for initial rough focusing before using the fine adjustment knob for precise focusing.
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.
The coarse focus adjustment knob is used to move the objective lens closer to or further away from the specimen in large increments, allowing for quick focusing at a general level. This adjustment is typically used initially to bring the specimen into view before fine-tuning the focus with the fine focus knob.
You should turn the coarse adjustment knob to raise the body tube of a microscope. This knob is larger and moves the body tube more quickly than the fine adjustment knob, which is used for precise focusing.
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.
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.
The coarse adjustment knob should be used first to bring the specimen into general focus. Then, the fine adjustment knob can be used for precise focusing.

The big knob on a microscope is typically called the coarse focus knob. This knob is used to move the objective lenses closer to or further away from the specimen, allowing for rough adjustment of the focus.
Coarse adjustment knob is used for initial rough focusing by moving the lenses further or closer to the specimen. Fine adjustment knob is used for fine-tuning the focus for sharper clarity by making small adjustments to the position of the lenses.
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.
The coarse adjustment knob is used to make large adjustments to the focus of the microscope, bringing the specimen into view. The fine adjustment knob is used for precise focusing by making small adjustments to the sharpness of the image. The combination of both knobs allows for clear and accurate visualization of the specimen.
This is the coarse adjustment knob. This should be used before the fine adjustment knob (the smaller knob) - which is for fine focusing.
