on the object you would like to observe (see
section 3.4).
a) surface illumination (light from above),
b) substage illumination (light from below) or
c) surface and substage illumination (light
from above and below at the same time).
If you press the On/Off button (16) once,
the surface illumination (5) will be turned on.
If you press the button a second time, the il-
lumination switches to substage (8). If you
then press the button a third time, both sur-
face and substage illumination are engaged.
Another press of the button turns the lighting
completely off again.
Choosing the right lighting depends on what
you would like to look at (see section 3.4).
3.2 Live Observation
If you press the camera shutter release (2)
on your microscope, the "CamApp" window
opens. A (in general blurry) live image is dis-
played on the monitor. Focus the live image
by turning the setting wheels for the image
sharpness (11).
3.3 Choosing the magnification settings
You should begin your first observations with
the smallest magnification (20x). This makes
adjusting the image much easier. Because the
higher the magnification, the more carefully
the object of observation must be positioned
(with the transmitted-light microscope, for
instance, a slide would be the object of ob-
servation). Therefore, turn the magnification
adjustment knob (3) to "20x". Then, adjust the
microscope stage (7) to its lowest position us-
ing the focus adjustment knobs (11).
3.4 Observing an Object
When observing objects through a micro-
scope, you must distinguish between trans-
parent and opaque objects. Transparent
objects are generally completely flat, or liq-
uid (e.g. insect wings, a drop from a puddle,
etc.); opaque objects are generally larger and
not so flat (e.g. smaller insects, plant pollen,
rocks, coins, etc.).
3.5 Observing Transparent Objects
Your Digital Microscope comes with so-called
"permanent slide preparations". These are
slides on which transparent objects have al-
ready been mounted and prepared for obser-
vation with a microscope. Set one of these
permanent slide preparations onto the micro-
scope stage (7). Push the slide underneath
both slide clips on the microscope stage, so
that nothing can move about during the obser-
vation. Then, turn the light to substage illumina-
tion (8) by pressing the On/Off button for the
light (16) as described in section 3.1. In the
next step, adjust the permanent slide so that
the observation object is clearly visible on the
monitor, in the preview area of the camera soft-
ware. Now, slowly turn the focus adjustment
knob (11) left or right until the image depicted
is in focus. By pushing multiple times on the
buttons for light brightness (+/-) (15), you can
set the illumination such that the fine details of
the observation object appear clearly on the
monitor as well.
If you would like to switch to a higher magnifi-
cation, turn the magnification adjustment knob
(3) to the left, to the position "80x" or "350x".
Important:
Each time you adjust the magnification, you
must also use the magnification adjustment
knob (3) to change the focus.
3.5.1 Observing Opaque Objects
If you would like to observe opaque objects
with this microscope, the object must be lit
from above. Therefore, use the On/Off but-
ton for the illumination (16) to set the lighting
to surface illumination (5), as described in
section 3.1. Place the observation object on
the small, round disk in the middle of the mi-
croscope stage. Using the focus adjustment
knob (11), focus the image. It will also then
appear in focus on the monitor. You might
