C. CALIBRATION AND MEASUREMENT
The Celestron Micro Capture Pro software includes a
+
measurement feature. To use this feature, you must first
perform a measurement calibration.
Make sure the X, Y Guide is set to "On" by selecting it in
+
the Options Menu.
Take a still image. The image will be displayed in the
+
column on the right side of the screen.
Click on the Calibration icon
+
Click and drag a line across a "known value" on the ruler image.
+
Try to keep the line as perpendicular to the lines on the ruler as
possible.
The "Adjust magnification" window will pop up as shown here.
+
In the box "Actual Dimension", enter the "known value" from the
+
calibration ruler.
Set the height of the microscope and focus on your
+
specimen. Then, replace your specimen with the
calibration ruler.
Re-adjust the focus and align the calibration ruler so that
+
the lines on the ruler are parallel with the vertical line on
the X, Y Guide.
Double click the saved image to open it in the Image
