SD card (not included in delivery)
If you want to store photos or videos with your microscope,
you need an SD card up to 32 GB.
Insert the card into the slot (Fig. 2 Fig. 12) until it clicks into
place. You can also do this when the device is switched on.
To remove it, press the SD card until you hear a clicking
sound. Now you can easily pull it out.
If the shutter button is pressed when the SD card is not inser-
ted, an error message appears: „No card".
General/location
Select a suitable location before starting to set up your
microscope. First make sure that your microscope is standing
on a stable, vibration-free surface. In order to put the
microscope into operation, the power supply provided must
be connected to the microscope (Fig. 1, image 7/11) and a
230 V plug socket. The appropriate illumination is switched
on using the switch (Fig. 1, image 20/21), and the brightness
is controlled for optimum illumination of the specimen by
turning the selection wheel. (For safety reasons, please only
use the power supply provided. Other power supplies may
not meet the required technical specifications. Damage to the
device caused by other power supplies is not covered by the
guarantee.)
Electric LED illumination with dimmer
Transmitted light illumination (Fig. 1, image 6) is used for
transparent specimens (specimens on microscope slides).
Select incident light illumination (Fig. 2, image 15) to observe
opaque objects. The simultaneous use of transmitted
and incident light illumination is only advisable with semi-
transparent objects. This mode is not recommended for
transmitted light objects on slides since too much light may be
reflected on the slide.
Colour filter wheel
The colour filter wheel (Fig. 1, image 8) beneath the microscope
table can be used to influence the image quality when
observing transparent specimens. Fine details are displayed
better depending on the colour and object. A coloured lower
light in combination with a white upper light can also optimise
image details when observing objects under incident light (e.g.
transparent objects).
Observation
Turn the nosepiece (Fig. 1, image 3) to select the 4x objective
for observing objects. Depending on the object, select upper
or lower lighting for optimum illumination.
To do this, place a permanent specimen directly under the
objective on the microscope stage (Fig. 1 Fig. 5) by clamping
it into the cross stage (Fig. 2 Fig. 16). To do this, first press the
lever for the clamp holder (Fig. 2 Fig. 17) to the side, place the
permanent specimen on the cross table and let the clamp hol-
der carefully return to the permanent specimen. The object to
be observed must lie exactly above/below the illumination. To
achieve this, there are two knurled screws on the cross table,
the so-called cross table drives (Fig. 2 Fig. 18, 19). By turning
these screws it is possible to position the object exactly, to the
right or left (Fig. 2 Fig. 18) and to the front or back (Fig. 2 Fig. 19).
To focus the specimen, first turn the coarse focusing knob
(Fig. 2 Fig. 10, inner knob). Precise focusing is achieved
with the fine focusing (Fig. 2 Fig. 10, outer rotary knob).
To change the magnification,
ece (Fig. 1 Fig. 3) onto the 10x objective. Now focus
the image with the fine focus only. For the 40x objecti-
ve, proceed in the same way as for the 10x objective.
The dimmers (Fig. 2, image 20) and (Fig. 2, image 21) can be
used to optimally adjust the contrast and quality of the image
of the object under observation.
Turn the nosepiece (Fig. 1, image 3) to switch objectives if
increased magnification is desired. Incidentally: The higher
the level of magnification, the more light is required for good
image quality.
Incident light illumination is optimised for the 4x objective. The
specimen is generally no longer fully illuminated if the 10x or
40x objective is used.
Digital zoom (up to 4x)
The screen magnification can be increased to a maximum of
4x by „stretching" with two fingers. By „pushing together" the
image can be reduced back to its original size.
Hide/show on-screen menu
By pressing on a free area of the screen, the menu can be
shown or hidden.
Connection to a PC/Laptop
You can transfer images and videos stored on an SD card to
a PC/laptop.
To do this, put the microscope into operation. Then plug the
USB cable supplied into the USB socket of the microscope
(Fig. 2 Fig. 13) and into a free socket on the PC/laptop.
The message „Connecting" appears on the screen. If it goes
out, you can access the SD. The microscope is now recog-
nized as a mass storage device.
Log off the microscope properly to exit. Pull out the USB cable.
Press and hold the on/off switch for about 2-4 seconds. The
microscope turns off, which is signaled by a beep.
HDMI connection
The microscope can transmit the image to a device with HDMI
input (e.g. monitor, TV set or beamer).
