Use
Illumination. Connect your microscope to a power outlet. Turn the power on; the power
џ
indicator will come on. You can change the level of brightness with the brightness adjustment
wheel.
Iris diaphragm is incorporated into the condenser. Adjust the iris diaphragm to match the
џ
numerical aperture of different objectives. Open or close the iris diaphragm with the adjusting
knob. When the knob is on the right, the iris diaphragm is fully opened.
Placing the specimen. Place the specimen on the stage and cover it with glass. Make sure to
џ
fix the specimen securely with the stage clips. Move the stage in horizontal and vertical
directions to point the objective lens at the specimen.
Focusing. Select the objective lens with the lowest magnification rotating the revolving
џ
nosepiece. Raise the stage turning the coarse focus knob. While observing through the
objective lens, turn the coarse focus knob slowly to let the stage down until you see an image
of the observed specimen. Turning the fine focus knob, make the image sharp. CAUTION: The
objective should not touch the specimen; otherwise, the objective and/or the specimen might
be damaged.
Adjusting the eyepiece head. Adjust the eyepiece tubes to make the view in the left and right
џ
eyepiece even. Start the diopter adjustment with "0" value and continue until the image
becomes sharp.
Immersion oil. For observing at high magnifications with a 100x objective lens, you have to use
џ
immersion oil. Place a drop of immersion oil on the specimen. Turn the revolving nosepiece to
place the 100x objective lens in its working position. Raise the microscope stage with a coarse
focus knob until the bottom of the objective lens touches the oil drop. Move the revolving
nosepiece back and forth to get rid of air bubbles in the oil. Then, fix the objective lens in its
working position. Make sure that oil fills the entire space between the objective lens and the
specimen.
Changing the bulb. The microscope is equipped with built-in LED illumination. Change the bulb
џ
only if necessary.
Digital camera
Levenhuk D900T comes with a 10Mpx digital camera. The camera allows you to observe
specimens in fine detail and true colors on your PC monitor and save images on the hard drive.
Connect the camera to your PC via a USB cable that also acts as a power cable.
