Levenhuk D670T Digital Trinocular Microscope - Manual (Page 6)

Insert eyepieces into the binocular head and attach objective lenses to the revolving nosepiece
in ascending order. Place a specimen in the middle of the stage and hold it in place with stage
clips.
Connect your microscope to a power outlet and adjust the brightness of illumination. When you
finish your observations, always dim the illumination before unplugging the instrument.
Start at the lowest magnification and center the observed specimen. Afterwards, switch to a
higher magnification by rotating the revolving nosepiece. If the image is out of focus, you can
use the fine focus system to adjust it. When using a 100x objective lens, you have to fill the
space between the lens and the specimen with immersion oil. There should be no air bubbles in
the oil, as this will reduce the resulting quality of the image.
For the best quality of your views, illumination has to be carefully adjusted. When switching to
a different objective lens, you will most likely have to readjust the iris diaphragm and the
illumination brightness.
If you need to change the light bulb, unplug your microscope, wait for the bulb to cool and
change it. Note that the lamp has to be leveled and inserted all the way to the end.
