When a very close view of the specimen is necessary. You can focus in on one part of the specimen.

The low power objective is used first for two reasons: First, focusing the low power objective will insure that the other objectives will be at the proper height. Smashing a slide with an objective can damage the objective. Second, you can see a greater area with the low powered objective. This allows you to easily locate an object of interest, center it in frame and then zoom in on it.
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.
One can obtain a total magnification of 400x while using an objective lens of 40x. Such a lens should be used along an eyepiece of 10x.
The size of the cell remains the same no matter what power objective is used. However, the magnification changes between these two objective lenses, with the low power objective magnifying it less than the high power objective.
The low power objective lens is usually a 10x lens and it is used to orient the specimen and get it focused before switching to a higher power lens.

The high power objective on a microscope is used anytime you need to achieve greater detail and magnification, and is often used when identifying cells. The high power objective is generally not used in teaching/learning labs as it is usually an oil immersion lens. Using oil means greater cleaning & care is required.
The high power objective on a microscope increases the magnification of the specimen, which allows you to see more detail. It allows you to see a close up of only a small area of the specimen being viewed.

Might add extra, but i really hope this helps! scanning objective - for locating the specimen on the slide (= low power objective) high power objective - magnifies the specimen to provide a detailed image coarse adjustment - used to focus the image when using low power diaphragm - used to adjust the amount of light passing through the specimen revolving nosepiece - holds the three objective lenses - it can be rotated to change the objective in use arm - holds the stage and the lens system - can be used to tilt the microscope (but not advised) substaGe lamp - provides a uniform illumination (more reliable than daylight !!)
