2. Unpacking and assembly
The microscope is packed in a molded styro-
foam container.
• Take the container out of the carton remove
the tape and carefully lift the top half off the
container. Be careful not to let the optical
items (objectives and eyepieces) drop down.
• To avoid condensation on the optical com-
ponents, leave the microscope in the original
packing to allow it to adjust to room tem-
perature.
• Using both hands (one around the pillar and
one around the base), lift the microscope
from the container and put it on a stable
desk.
• Put the head onto the top of the stand and
tighten the head-lock-screw. Insert the eye-
piece into the tube.
3. Operation
3.1 General information
• Set the microscope on a level table.
• Place the object to be observed in the center
of the object plate. Use the clips to fasten it
into place. Make certain that the specimen is
centered over the opening in the stage.
• Connect the plug-in power supply to the net
and turn on the switch to get the object illu-
minated.
• To obtain a high contrast, adjust the back-
ground illumination by means of the iris dia-
phragm and the variable illumination control.
• Rotate the nosepiece until the objective with
the lowest magnification is pointed at the
specimen. There is a definite “click” when
each objective is lined up properly.
NOTE: It is best to begin with the lowest power
objective. This is important to reveal general
structural details with the largest field of view
first. Than you may increase the magnification
as needed to reveal small details.
To determine the magnification at which you are
viewing a specimen, multiply the power of the
eyepiece by the power of the objective.
• Adjust the coarse-focusing-knob which
moves the stage up until the specimen is fo-
cused. Be careful that the objective does not
make contact with the slide at any time. This
may cause damage to the objective and/or
crack your slide.
• Adjust the fine-focusing-knob to get the im-
age more sharp and more clear.
• Colour filters may be inserted into the filter
holder for definition of specimen parts.
Swing the filter holder out and insert colour
filters.
• Use the knobs of the mechanical stage to
move the slide side-, back- and forwards.
The vernier provides accurate location of the
specimen area.
• Always turn off the light immediately after
use.
• Be careful not to spill any liquids on the mi-
croscope.
• Do not mishandle or impose unnecessary
force on the microscope.
• Do not wipe the optics with your hands.
• Do not attempt to service the microscope
yourself.
3.2 Installation of the software
• Insert the installation CD into the computer’s
CD drive.
• Follow the installation instructions (see also
the description of the software on the instal-
lation CD).
3.3 Displaying images on the computer
• Connect the microscope to the computer
using the USB cable.
• Start up the software.
• After clicking on the camera icon in the tool-
bar, the image of the specimen will appear
on the computer screen.
• If necessary, re-adjust the brightness and
contrast using the iris diaphragm and the va-
riable illumination control.
• Adjust the sharpness of the image by means
of the focusing knobs of the microscope.
• If necessary, adjust the settings of the ca-
mera in the video window according to the
particular requirements.
• For further work using the software, see the
instructions for the software that are on the
installation CD and the help files in the soft-
ware.
