Calibration and measurements

It is recommended to calibrate the system before proceeding with

Calibrating

Before calibrating the microscope, turn the grid display on. To do so, select
on from Options > X (Grid). 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.

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 field.

The application will automatically calculate the magnification of the image.
Click OK to close the dialog window. The calculated magnification will be
displayed in the Magnification field.

Note: chosen points should form a horizontal line.

You can check calibration results by measuring the same distance with the

Any Angle Line tool. Click the measurements icon, choose the Any Angle
Line tool and draw a similar line on the image. If the measured distance is

equal to the actual distance, calibration has been successful.

Measurements

This section explains all the measurement tools.

Any Angle Line

Press and hold the left mouse button to start drawing a line. Release the left
mouse button to complete the line.

Continuous Line

Use this tool to draw a curve on the image and measure its length.

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

Place three points on the image with your mouse. The application will
automatically calculate the angle value.

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
