Microscope assembly
The battery has to be fully charged before turning the microscope on for the rst
time. Plug the power cable into the power cable socket on the microscope body (14)
and connect it to a power source. The battery status indicator (6) will turn red. Once
the battery is fully charged, the indicator will go out. You can now disconnect the
microscope from the power source and turn it on. The fully-charged battery allows
you to use the microscope for three hours. The illumination will grow dim and the
image quality will decrease to inform you that the battery is low. Charge the battery, as
described above.
A microSD card (purchased separately) is required to save captured images and
recorded videos. Turn the microscope o and insert the microSD card into the
corresponding slot on the microscope body until it locks in place with a click. Do not
apply excessive force when inserting the microSD card. Try rotating the card, if it does
not lock in place with ease. Format the card before using it. To turn the microscope on
press the power button (15). To turn the microscope o press the power button (15)
again (refer to Power saving for more information).
Display icons
Note: Interface icons will be hidden if no key has been pressed and held for 10 seconds.
Capturing an image
Turn the microscope on and place a specimen on the stage. The height of the
objective lens can be regulated with height adjustment knobs (8). Adjust the
illumination brightness, so that the specimen is evenly lit. You can use upper or
lower illumination. Change magnification and focus your view, if necessary. Press
the capture button (9).

and focus your view. Make sure that the vertical axis of the grid is parallel to scale divisions
and capture an image. Double-click the image thumbnail to open it in a separate window.
Click the corresponding icon on the toolbar to begin calibration. Using your mouse,
choose two points on the image (you have to know the actual distance between these two
points). Once you choose the second point, a dialog window will open, where you have to
enter the known distance in the Actual dimension eld. The application will automatically
calculate the magnication of the image. Click OK to close the dialog window. The
calculated magnication will be displayed in the Magnication eld.
Note: Chosen points should form a horizontal line.
You can check calibration results by measuring the same distance with the Straight line tool.
Click the measurements icon, choose the Straight line tool and draw a similar line on the
image. If the measured distance is equal to the actual distance, calibration has been successful.
Recalibration
The calibration process has to be repeated if the magnication or focus has been changed
during observations.
Click the corresponding icon on the toolbar again and select Reset picture magnication
from Reset magnication. Repeat the calibration process, as described above. Change the
magnication and capture a few images. Double-click one of the thumbnails to open the
resulting image in a preview window. Click the calibration icon on the toolbar and select
Set picture magnication from Set magnication. Enter the current magnication in the
dialog window that appears and click OK.
If you want to use the same magnication when capturing images in the future, click the
calibration icon on the toolbar and select Set capture magnication from Set magnication.
