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.
