LCD Module
This digital microscope is different than traditional microscopes --- instead of using eyepieces to look at a specimen in a traditional
microscope, the LCD monitor replaces the eyepieces so you can look at the specimen on the screen by yourself or share the views with
others. To begin to view specimens with your microscope, you will have to turn the LCD monitor on by turning the Power Button “On”
(see Figure 4). Push the button once and shortly the Monitor On LED (red color) will come on indicating the LCD monitor is “On”.
That is basically all you need to do to use the LCD screen for viewing specimens. The various keys on the LCD Module are mainly used
for taking images (snapshots and video) and will be discussed later in this manual.
Illumination
1. To turn the illuminator on, see Figure 5 below and turn the control dial to the left.
2. The illuminator is used for specimen slides where the light shines up through the hole
in the stage through the slide.
3. Rotate the illuminator dial to the brightness level desired when viewing specimens.
Figure 5
Adjusting the Lighting
Specimens of different size, thickness, and color variations will require different levels of illumination. There are two ways to change the
amount of illumination when viewing a specimen; adjusting the brightness on the dial shown above in Figure 5 and changing the EV
function on the LCD monitor. The EV (exposure value for brightness) function increases or decreases the brightness level by using the
Left and Right arrow keys on the LCD monitor.
When viewing a specimen that is not transparent or dark in color, you may need to increase the amount of light to resolve certain features
or details. This is best done by simply increasing the brightness of the illuminator by rotating the brightness control dial all the way to its
highest setting.
Optimum lighting will be found by experimenting with adjustments as each specimen may require slightly different illumination as well
as the same specimens viewed under different powers.

Viewing a Specimen
Your instrument is provided with a fixed, simple stage with holding clips to guide the positioning of the slide holder.
1. Place a specimen slide - 1” x 3” size (25mm x 76mm) into the slide holder. Do this by gently placing the specimen slide under the
small guides of the slide holder (Figure 6). Then, push the slide all the way into the cutout in the slide holder.
2. The slide holder with slide inserted will be placed onto the stage with the arrow on the slide holder pointed forward.
Inside the stage (Figures 7 & 8) are two small holding clips under which the slide holder is to be inserted.
3. Push the slide holder in until you begin to see the specimen (remember to start at the lowest power). You can examine the specimen
by moving the slide holder back and forth slowly and moving it slightly to the left or right.
4. For slides that have the specimen off to one side you may not be able to see the entire specimen and in these cases you can then
remove the slide from the slide holder and rotate the slide 180° and try again.
5. Manually moving the slide holder may seem difficult at first but after experimenting it becomes quite easy to use.
Figure 6 Figure 7 Figure 8
Once the slide is in place you will be ready to start viewing by setting the power.
6. Use the power knob (in the center of Figure 9) to rotate the objective lenses until the 4x
dot is lined up near the indicator – it will click when positioned correctly. Always start
with the lowest power objective (4x with this microscope) which gives you 24 power and
work your way up to higher powers. At 24 power you will have the widest field of view
and the brightest image.
7. Look at the LCD screen while turning the focus control (Figure 9) until the specimen
comes into view. You may need to position the slide specimen as discussed above so the
image is in the field of view.
8. With the 4x objective lens, you can also vary the power anywhere from 24x to 192x by
using the digital zoom of the LCD module. Use the direction keys (Up/Down) on the
LCD module to use the digital zoom. On the left of the screen will be an icon indicating
what digital zoom setting you are at. Note: Digital zoom is best up to 4x.
9. For
higher powers, you will need to rotate the power knob to the 10x objective position
for medium power and to the 40x objective for the maximum power. You will have to
refocus when changing the power of the objective lenses. While using either of the 10x
or 40x lenses you also can increase power by using the digital zoom.
Note: At maximum powers the images may not be as sharp and dark. Your best views will be at the lower powers.

Digital Imaging
You can take snapshots or a short video with your microscope using the built-in digital camera. With the internal storage memory, you
do not need to use a PC or any other devices to do imaging. Transferring of images to your PC for saving and or printing them is easy
and will be discussed later in this manual.
Note: If you are going to take images, do not connect the USB cable to your PC or damages could occur to the equipment. The
USB cable is not used at all for taking images!

LCD-Modul
Dieses Digitalmikroskop unterscheidet sich von herkömmlichen Mikroskopen: Anstatt wie in einem herkömmlichen Mikroskop die Proben
durch ein Okular zu betrachten, ersetzt der LCD-Monitor die Okulare und ermöglicht Ihnen die Betrachtung der Proben auf dem Bildschirm
allein oder auch gemeinsam mit anderen Personen. Vor der Betrachtung von Proben müssen Sie Ihren LCD-Monitor einschalten, indem Sie
den Netzschalter einschalten (siehe Abb. 4). Drücken Sie die Taste einmal. Kurz darauf leuchtet die Monitor-LED (rot) auf und zeigt an,
dass der LCD-Monitor eingeschaltet ist. Das ist im Grunde alles, was Sie wissen müssen, um den LCD-Monitor zur Betrachtung von Proben
zu verwenden. Die verschiedenen Tasten auf dem LCD-Modul dienen hauptsächlich zur Aufnahme von Bildern (Schnappschüsse und
Video) und werden weiter unten in dieser Bedienungsanleitung besprochen.
Beleuchtung
1. Abb. 5 unten zeigt, wie die Beleuchtung eingeschaltet wird: Drehen Sie den Drehregler nach
links.
2. Die Beleuchtung wird für Objektträger verwendet. Das Licht leuchtet durch die Öffnung im
Objekttisch durch den Objektträger.
3. Drehen Sie den Beleuchtungsdrehregler, um die gewünschte Helligkeit für die
Probenbetrachtung einzustellen.
Einstellung der Beleuchtung
Abb. 5
Proben von unterschiedlicher Größe, Dicke und Farbvariation erfordern unterschiedliche Beleuchtungsstufen. Es gibt zwei Möglichkeiten,
die Lichtmenge bei der Probenbetrachtung zu ändern: Einstellung der Helligkeit auf der Drehscheibe, die oben in Abb. 5 gezeigt ist, und
Änderung der EV-Funktion auf dem LCD-Monitor. Die EV-Funktion (Exposure Value for Brightness/Belichtungswert für Helligkeit) erhöht
oder reduziert die Helligkeitsstufe. Hierzu werden die Links- und Rechtspfeile auf dem LCD-Monitor verwendet.
Bei der Betrachtung von nicht transparenten oder dunklen Proben empfiehlt es sich u. U., die Lichtmenge zu erhöhen, um bestimmte
Merkmale oder Details aufzulösen. Das erreicht man am besten durch die Erhöhung der Helligkeit der Beleuchtung durch Drehen des
Helligkeitsreglers auf die höchste Einstellung.
Zur Erzielung der optimalen Beleuchtung werden Sie etwas mit den Einstellungen experimentieren müssen, denn jede Probe erfordert u. U. eine
leicht abweichende Beleuchtung. Das gilt auch für die gleichen Proben bei Betrachtung mit verschiedenen Vergrößerungsleistungen.
Betrachtung einer Probe
Das Instrument ist mit einem festen, einfachen Objekttisch mit Halteklemmen zur Führung der Positionierung des Objektträgerhalters
ausgestattet.
1. Setzen Sie einen Probenobjektträger (25 x 76 mm, 1 x 3 Zoll) in den Objektträgerhalter. Dazu setzen Sie den Probenobjektträger
vorsichtig unter die kleinen Führungen des Objektträgerhalters (Abb. 6). Dann schieben Sie den Objektträger ganz in den Ausschnitt
des Objektträgerhalters.
2. Der Objektträgerhalter mit eingesetztem Objektträger wird so auf den Objekttisch gesetzt, dass der Pfeil auf dem Objektträgerhalter
nach vorn zeigt. Im Innern des Objekttisches (Abb. 7 und 8) befinden sich zwei kleine Halteklemmen, unter denen der
Objektträgerhalter eingeschoben wird.
3. Drücken Sie den Objektträgerhalter ein, bis Sie die Probe sehen (immer mit der geringsten Vergrößerungsleistung beginnen). Sie
können die Probe untersuchen, indem Sie den Objektträgerhalter langsam hin und zurück und leicht nach links oder rechts schieben.
4. Bei Objektträgern, auf denen sich die Probe auf einer Seite befindet, ist möglicherweise nicht die ganze Probe zu sehen. In diesen Fällen
können Sie den Objektträger aus dem Objektträgerhalter nehmen, den Objektträger um 180° drehen und es dann noch einmal probieren.
