The stereo zoom microscope allows three-
dimensional viewing of objects in 7x to 45x
magnification and a eyepiece camera (e.g.

for documenting work in the form of photographs
and videos.
The microscope 1013377 is for operation with a
mains voltage of 115 V (±10%), and the
1013378 unit is for operation with 230 V (±10%).

3. 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 compo-
nents, leave the microscope in the original pack-
ing to allow it to adjust to room temperature.
•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-
pieces into the tube.
•Screw the housing for the top light into its
holder and plug the power supply connector
into the socket on the stand pillar.
•Insert the object plate into the stage opening
in the base.
4. Operation
4.1 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.
•Connect the mains cable to the net and turn
on the switch to get the object illuminated.
•When using transmitted- or mixed-light illu-
mination replace black and white plate with
the glass plate.
•Adjust the interpupillary distance between
the eyepieces by grasping the two prism-
housings with both hands and moving them
until one circle of light can be seen.
•Use the knob for the zoom objective to set
the required magnification.
•Focus the object by turning the side knobs.
•It might be necessary to loosen the lock-
screw and raise or lower the entire stereo
head-bracket until the outline of the object is
found in the field of view.
•Be sure to tighten the lock-screw to fix the
height of the stereo head on the pillar.
•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.
4.2 Changing the lamps
•Turn off the power switch, unplug the mains
plug and let the lamp cool down.
•In order to change the bulb for the top light,
undo the screw at the side, remove the lamp
housing and remove the plug from the stand
pillar.
•Use a flat tool (e.g. screwdriver) to gently (!)
lift the clip and pull the lap socket out of the
housing (see Fig.1).
•Replace the faulty bulb with a new one.
•Screw the lamp housing back into the holder
and connect the power supply again.
Fig. 1 Changing the bulb in the top light
•To change the lamp of bottom light remove
the cover from the base opening.
•Replace the defect the lamp by a new one.
•Remount the cover.
4.3 Changing the fuse
•Turn off the power switch and unplug the
mains plug.
•Unscrew the fuse holder on the back of the
stand base with a screwdriver.
•Replace the fuse and reinsert the holder in
its socket.
4.4 Fitting an ocular camera
•Screw the camera adapter onto the vertical
eyepiece.
•Put the ocular camera in the adapter and
connect it to a computer.
The camera can be put into use by means of the
slider for changing the beam path.

When the slider is pushed all the way in, the
object can be viewed through the binocular eye-
piece.
When the slider is all the way out, the camera is
activated so that photos or videos can be re-
corded.
5. Storage, cleaning, disposal
•Keep the microscope in a clean, dry and
dust free place.
•When not in use always cover the micro-
scope with the dust cover.
•Do not expose it to temperatures below 0°C
and above 40°C and a max. relative humid-
ity of over 85%.
•Always unplug the mains plug before clean-
ing or maintenance.
•Do not clean the unit with volatile solvents or
abrasive cleaners.
•Do not disassemble objective or eyepieces
to attempt to clean them.
•Use a soft linen cloth and some ethanol to
clean the microscope.
•Use a soft lens tissue to clean the optics.
•The packaging should be disposed of at
local recycling points.
•Should you need to dis
-
pose of the equipment it-
self, never throw it awa
y
in normal domesti
c
waste. Local regulations
for the disposal of electri-
cal equipment will apply.
