Calibrating

Before calibrating the microscope, turn the grid display on. To do so, select on from Options > Crossing. 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.

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.

• 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.

Draw and text

MicroCapture Pro allows you to add drawings and textboxes to your images. Open an image in a preview window and click the Pencil icon on the toolbar. Select one of the tools from the drop-down menu and draw something on the image. By clicking the TT icon on the toolbar, you can edit font type and color to be used in textboxes.
