6.5.2 Scan Analysis

After transferring the scan images to your computer (as described in section 6.8.6 “Copy files to USB

stick” on page 69), you will now see a scan that is a straight line. This scan is now ready to begin the
analysis.

To see the differences within the scan rotate it to the side.
