Using The Microscope - Levenhuk LabZZ 101 Guia Del Usuario

Using the microscope

Getting started
• Unpack the microscope and make sure all parts are available.
• Move the stage to the lowermost position using the focusing knob.
• Make sure the batteries are correctly installed in the battery compartment; insert new batteries
if required.
• Insert the eyepiece into the eyepiece tube.
• Slowly adjust the illumination brightness, from dark to light.
Focusing
• Place a specimen on the stage and fix it with the holders.
• Select the 4x objective rotating the revolving nosepiece.
• Move the specimen to place its thickest part exactly under the objective.
• Rotate the focusing knob to slowly raise the stage until the objective is close to the specimen;
keep checking the distance between the objective and the object to avoid their contact.
CAUTION: The objective should not touch the specimen, otherwise the objective or/and the specimen
might be damaged.
• Look through the installed eyepiece and lower the stage slowly rotating the focusing knob until you
see the specimen image.
• Such adjustment protects the frontal lens from contacting the object when you use objectives of other
magnifications; though, slight refocusing might be required.
• If the image is too bright, rotate the diaphragm disk until the passing light ray is reduced to a
comfortable brightness level. If the image is too dark, select a larger aperture to increase the light ray.
Selecting the objective
Start your observations with the lowest magnification objective and select a specimen segment for
detailed research. Then move the specimen to center the selected segment in the field of view, to
make sure it keeps centered when the objective is changed to a more powerful one. Once the segment
is selected, you should center its image in the microscope's field of view as precisely as possible.
Otherwise, the desired segment might fail to center in the field of view of the higher power objective.
Now you can switch to a more powerful objective by rotating the revolving nosepiece. Adjust the image
focus if required.
