Course Adjustment and Fine Adjustment Knobs.
The coarse adjustment (up or down) is used to quickly move closer to or away from the focal point of the specimen. The fine adjustment is then used to fine tune the focus and bring the specimen into clear view.Coarse adjustment means big movements up or down. Fine adjustment means very small movements until the specimen is 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.
