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.
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 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 the 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 the 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 the value of the resulting angle.
Draw and text
PortableCaptureHD allows you to add drawings and text boxes 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 text boxes.
Working with the application for Mac OS users
Browse to the mac folder on the installation CD and copy the PortableCaptureHD file to the desktop. Use a USB cable to connect the microscope to your computer. Run the PortableCaptureHD application by double-clicking its icon.
A magnified image of the observed specimen may be seen in the main window of the application. From the Options menu, select Preview Size to set the image resolution. Keep in mind that the preview window cannot be resized (the standard resolution is 640×480). The image resolution is shown in the bottom left corner of the preview window.
From the Options menu, select Date/Time to display or hide the date and time of capture during the preview.
