5. MICROSCOPE SETTINGS

ESTABLISHING A MAINS CONNECTION

A
ATTENTION! Before setting up the microscope, check that the on/off
switch (main switch) (1) is in the O (OFF) position.
To start up the microscope, first insert the hollow plug (2) on the supplied
power adapter (12V, 4A) (3) into the power-in socket (4) on the back of
the microscope. Then plug the mains plug (5) on the power adapter into a
suitable socket (6) (max. 230V).
To switch on the microscope, move the on/off switch (main switch) (1) to the
'I' position.

POSITIONING THE SPECIMEN

B
The clamp holder (1) on the specimen stage is designed to hold a microscope
slide (2). The longitudinal XY stage (3) (for movement in the longitudinal
direction) and the transverse XY stage (4) (for movement in the transverse
direction) are coaxial. The specimen stage can therefore be moved according
to your requirements.
Swivel the 4x objective (5) into the working position by turning the nosepiece
(6).
NOTE: The lenses engage with an audible "click" when they are positioned
in the beam path.

CONFIGURING THE LIGHT

C
The lamp housing (1) is located in the microscope base.
The light is supplied by a halogen bulb (12V/30W).
You can adjust the brightness of the light source using the stepless dimmer
(2).
WARNING: Do not leave the dimmer at maximum brightness for long
periods of time. This shortens the lifespan of the lamp.

CONFIGURING THE OBSERVATION TUBE

D
Adjusting the interpupillary distance (A) (distance between the eyepieces)
Set the correct interpupillary distance for binocular observation by swivelling
the eyepiece tubes (1) on the microscope head so that the right and left fields
of view overlap completely or combine to form a circular image.
Setting the visual acuity correction (dioptre compensation)
Turn the 40x lens to the working position. First, look only through the right
eyepiece with your right eye, and then use the coarse and fine focus knobs to
focus the image. Next, look only through the left eyepiece with your left eye,
and then use the dioptre adjustment ring (2) to focus the image.
