Microscope assembly
The battery has to be fully charged before turning the microscope on for the first 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 off 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 off press the power button (15) again (refer to Power saving for more information).

Calibration
Calibration
Before calibrating the microscope, turn the grid display on. To do so, select
On from Options > XY Guide. By default, the grid is visible. Place the
calibration scale on the stage 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.
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 magnification or focus has
been changed during observations.
Click the corresponding icon on the toolbar again and select Reset picture magnification from Reset magnification. Repeat the calibration process, as described above. Change the magnification 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 magnification from Set magnification. Enter the current magnification in the dialog window that appears and click OK.
If you want to use the same magnification when capturing images in the future, click the calibration icon on the toolbar and select Set capture magnification from Set magnification.
Measurements
It is recommended to calibrate the system before proceeding with measurements.
Straight line. Press and hold the left mouse button to start drawing a line.
Release the left mouse button to complete the line.
Continuous Line. Press and hold the left mouse button and draw a line. Release
the left mouse button to complete the segment. You can continue adding more
segments to the free-form line.
Radius Circle. Draw a straight line on the image. The application will
automatically calculate the radius, as well as circumference and area of the
corresponding circle. Diameter Circle. Draw a straight line on the image. The
application will automatically calculate the diameter, as well as
circumference and area of the corresponding circle. Three Points Angle. Press
and hold the left mouse button to draw a line on the image. Release the left
mouse button and draw another line. The application will automatically
calculate value of the resulting angle.
