Coarse Adjustment
For low power you can use the coarse adjustment and fine adjustment for high power you should only use the fine adjustment because on high power, the objective lens is too close to the slide and using the coarse adjustment may scratch the objective lens.
use the fine adjustment knob to get a better view of what you are looking at.For low power you can use the coarse adjustment and fine adjustmentfor high power you should only use the fine adjustment because on high power, the objective lens is too close to the slide and using the coarse adjustment may scratch the objective lens.

First of all, one should never call it high power, it is morecommonly called the "high objective", yet that is not what this question is asking. To answer the question: You use the fine adjustment knob. This knob should be located near the coarse adjustment knob, on the opposite side of the microscope (at the same height as the coarse adjustment knob), or even as a separate knob protruding from the coarse adjustment knob. The fine adjustment knob is smaller in size. You should never, ever use the coarse adjustment knob under the high objective, you could scratch the microscope slide, cover slip, high objective lens, or in a worst case scenario break the high objective lens.
it is the function of HPO or the High Power Objective
When working with a microscope you should always take procauctions but one question I am asked a lot is When working with a microscope do you open or close the diaphram when working with the medium- and high-power objective nobs? The answer is you keep it open if you don't you won't be abler to see any thing.
the stage adjustment knob is a knob that moves the stage go up anad down . you should use it on a lower power objective lens though
The coarse and fine adjustment knobs can be used with the low power objective.
I assume you would use the fine adjustment knob for high power objectives.

The fine adjustment knob is used with the power objective on the microscope. Since the objective is already at the highest objective possible for that microscope, using the coarse adjustment knob would focus to much on the object making the details harder to read. Using the fine adjustment knob, you are able to see the fine details within the object or organism you are studying. The higher the power, the finer the knob and the lower the objective, the coarser the knob and objective.
