It depends on what device it is to be used on? Basically, a coarse adjustment knob is used to get near (for example) a radio frequency. Then a fine adjustment knob is used to fine tune to the radio station. A microscope is another example where fine tuning is used to focus onto a specimen.
The fine adjustment knob in a microscope is used to make small, precise focusing adjustments to bring the specimen into sharp focus. It allows for fine tuning of the focus after coarse adjustments have been made using the coarse adjustment knob.
The fine adjustment knob on a microscope is typically located on one side of the base near the coarse adjustment knob. It is used to make precise focusing adjustments when viewing a specimen under high magnification.
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.
Scientists use the fine adjustment knob on a microscope to make precise adjustments to focus on the specimen at high magnifications. This knob allows for subtle changes in the focal point, which is important for observing fine details on the specimen.

Use a coarse adjustment knob (large movement) to get near, then use the fine adjustment knob (small movement) to fine-tune.

After you adjust the coarse adjustment knob, the fine adjustment knob makes it sharper or clearer.

The Fine Adjustment
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.
This is the coarse adjustment knob. This should be used before the fine adjustment knob (the smaller knob) - which is for fine 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.
