Clean the entire lens with special grit free ________________ only. Plug in the cord and ________________ on the light. Obtain a prepared slide and place it on the ____________ anchoring it with the _____________. Move the slide with the mechanical stage knobs until the ______________ appears to be directly on top of the __________________in the center of the stage. Always start focusing with the scanning _____________ in place. Use the ____________ adjustment knob to move the stage all the way____________. Now look through the _____________. Using the _______________ adjustment knob, lower the stage down slowly until the ___________________ comes into view. Center the ________________ in the field of view by turning the ________________knobs. To go to a higher magnification rotate the _________________ objective in place. Again use the________________ adjustment knob to focus. You need to turn the knob only slightly to focus because the microscope is _______________. This means that when objects are in focus at one magnification, they will remain in focus at ______________ magnifications. Once again ______________ the part of the image that you want to see in detail in the center of the ________________. Finally to go to high power you rotate the nosepiece to the ____________ objective. You now will focus the image by turning the _____________adjustment knob very ______________ to focus. If you centered the part of the image you wanted to see in _____________ you should now see the detail somewhere in the view.
