I am going to ignore your poor grammar skills on this one, but here is the answer.
You first start on a low power to locate the specimen or bacteria. Then you switch to a high power to get a better look at it. Hope this helps.
digital microscopes,compound microscopes,electron microscopes,pocket microscopes,usb computer microscopes,scanning microscopes,stereo microscopes.
On where you start is totally optional, but it is most beneficial to start on the lowest power, so that you can adjust your magnification from then on to make out the object your trying to see. Start low then work your way to high.

High powered microscopes have a light source and can magnify up to 1000 times.
Power magnifications are important in residential microscopes. Different magnifications on the market range from 40x, 10x and can be as high as 400x.
Microscopes vary in power. You can determine total magnification by the eyepiece and the lens.
magnifying glasses of outrageously high power!
3 lences in microscope1.high power ie 45x2.low power ie 10x3.oilimerson ie 10x
light microscopes direct light onto the slide and magnify it, light microscopes also have a high and low power objective lens which can magnify up to 10, 40, 43 and 100 times total magnification whilst electron microscopes shoot electrons at the slide which give more detail and accuracy but the disadvantage is it can't view objects in color. electron microscopes can magnify up to 500.000 times total magnification.Light microscopes aren't as strong as an electron microscope in respect to zooming power. The specimen can remain alive in light microscope but for electron microscopes, preparation of the slides will kill the specimen.
Meiji branded microscopes are manufactured in Japan. They are regarded as a very high quality microscope. Laboratories and jewelers use these microscopes.
Electron microscopes are more powerful in terms of magnification, compared to compound microscopes. They are capable of two million-power magnification, while compound microscopes are only capable of 1000x magnification.
