these screws it is possible to precisely position the object, in the left or
right direction (Fig. 3.27) and forwards or backwards (Fig. 3.26).
c) Then switch on the LCD monitor, by pressing the power switch on the
screen module (Fig. 1+2.12); the red operating light Fig. 1+2.11) will
light up. Then look at the LCD monitor (Fig. 1+2.2) and carefully turn
the focusing wheel (Fig. 1.16) until the image is sharp. With the stage you
can now center the object at the desired place on the LCD monitor.
d) For higher magnification turn the lens turret (Fig. 1.4) to a higher set
-
ting (objectives 10x and 40x).
Note:
Before you change the objective setting, first move the microscope table
fully downwards Fig. 1.7). This will avoid possible damage!
The higher the magnification, the more light is needed for a good image
quality.
Important notes:
Depending on the preparation in use, higher magnification in individual
cases will not lead to a better picture! The magnification is altered by
changing the objective. This alters the sharpness of the image which
must be adjusted by the focusing wheel (Fig. 1.16). Proceed here very
carefully. If you raise the microscope table too quickly, the objective and
the slides can touch each other and be damaged!
e) The magnification factor of the LCD eyepiece amounts to 12.5x. In
combination with the 4x-objective we obtain a total magnification of
40x, i.e. 1 mm of the object is shown as 40 mm on the LCD monitor.
With the 10x objective we have a total magnification of 125x, corre
-
spondingly, with the 40x objective 500x.
f) The color filter disc (Fig. 1+4.15, beneath the microscope table (Fig.
1+4.7) helps you when viewing very brightly or transparent prepara-
tions. For this please select the suitable color depending upon the object
being observed. The components of colorless or transparent objects (e.g.
grain containing starch, single-celled organisms) will be much easier to
recognize.
3.2 Operation of the screen module
3.2.1Observing the screen
If you switch on the LCD monitor (see section 3.1 c), you will see the
live image of your object as well as five different displays:
If you’ve set the LCD screen option (see section 3.1 c) then you’ll see a
live picture of your specimen with four different entries.
a) There’s a camera symbol at top left (photo mode) together with the
graphics resolution (number of pixels by width and height).
b) Bottom left the remaining sd card memory is shown in square brackets.
c) EV brightness correction is shown first bottom right. Press the up or
down arrows (illustration 2.20) to adjust brightness from -1.2 (dark) to
+1.2 (bright).
d) The electronic zoom factor is shown second bottom right next to a
magnifying glass symbol. Use the right and left arrows (illustration 2.20)
to enlarge the image by factors from 1 to 4. – Maximum LCD Micro
enlargement is hence 4 x 500 = 2000x.
3.2.2 Producing photographs
By pressing of the photo button “SNAP “(Fig. 2.21) a photograph is
taken of the live image, which is stored to your sd card.
3.2.3 Photograph management
By pressing the change button “ESC “(Fig. 2.23) you change from live
images to
the list of stored photographs. In the list, you can select a required
picture by pressing the appropriate arrow keys (Fig. 2.20); the selected
picture has a yellow border. To display it press the ”OK” input key (Fig.
2.20). By pressing “ESC”
you can return to the list, press “ESC “again to return to the live image.
By pressing the “MENU” button (Fig. 2.22) while displaying the list, a
menu bar appears, which you can control using the appropriate arrow
keys (Fig. 2.20, ). Here you can also change certain settings and bring
them into force by pressing the “OK” input key (Fig. 2.20).
Menu overview in list display.
a) File Protect, Lock, Unlock, Exit. Use the left arrow key to leave the
selection screen.
b) Del File – Current (delete chosen graphics file), All (delete all graph
-
ics files). This is queried for certainty reasons. If you decide yes use the
left arrow key to
go to OK and press OK. If not leave Cancel activated and press OK to
return to
the list.
c) Video (list of film records, Video Player), Picture (list of photo re
-
cords, Picture
View). Video can be reached from the picture list and vice versa.
d) Exit has the same effect as “ESC“.
3.2.4 Revise settings
By pressing the “MENU” button (Fig. 2.22) while displaying the live
image a menu bar appears, which you can control using the appropri-
ate arrow keys (Fig. 2.20). Here you can also change settings and bring
them into force by pressing the “OK” input key (Fig. 2.20).
Menu overview (during live image display):
a) Mode (photography mode): Single, Auto (at intervals given in Set-
ting), Setting (photo intervals in minutes and seconds, adjusted using
arrow keys and OK). Start the photo session with “„SNAP“; the count-
down to the next photo is shown in the middle of the screen. End it after
the next snap with ESC.
b) Size (pictorial resolution, width x height): A selection of different
resolutions are available.
c) Effect (graphical effect): Normal (normal positive color image),
Negative (negative image), Sepia (sepia shading), Black-White.
d) Date Label of the stored snaps: Setting (time), Yes (label), None (no
label).
If you’re in Setting press OK. Use the up and down arrows to change the
year shown by a yellow arrow. Use the right and left arrows to alter the
month and day in “Date“, the hours and minutes in “Time“. Select the
time set with OK - this will be acknowledged by brief display of “Suc-
cess”. The year, month and day of a picture is shown top left.
e) DV Record (mode for filming).
f) Exit (the menu).
3.2.5Produce and administer film
In this mode resolution is shown top left outside the image during live
picture display and the memory time available for film at bottom left.
The electronic zoom factor (1.0 to 2.0) is shown bottom right. Start film
-
ing with SNAP (illustration 2.21); press this key again to end filming.
During filming a camera symbol blinks at top left and the current filming
time is shown at bottom left. Film image resolution is 320 x 240. In Ef-
fect the same pictorial effects as for
photos are selectable. Use Capture to toggle between filming and
photographing. Use Exit or ESC to get out of the menu and then ESC
to revert to the live picture display. To view the stored films use ESC to
get to the photo list and then
MENU to get to the film list via Video (see section 3.2.3). Use the ar
-
rows to
choose a film, select it and then play it endlessly with OK. During play
use OK
to toggle between Pause (||) and Play ( ). Use the left arrow to choose
the
previous film (| ) and the right the next ( |). A strip showing a film
playing bar graph, play duration and functions is briefly displayed here.
This can also be shown using Snap if you want to know current status.
Use ESC“ to end the play
function. Delete films using MENU and DelFile as for photos (see sec
-
tion 3.2.3).
You can view your films and manage them on any connected PC (see
