High power on microscope?
On a the microscope I use, the ocular (eyepiece) has a magnification power of 10x. The 'low' (or 'scanning') objective lens is 4x, the 'medium' has a power of 10x, and the 'high' has a power of 40x. Multiply the ocular by the lens you're using to get your 'total magnification.' TIP: Only use the coarse adjustment knob while on 'low' power, then use the fine adjustment. Why? If you use the coarse adjustment knob on 'medium' or 'high,' there's a good chance you'll crack your slide. -BugCrunch

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.
