This completes installing the sample.
Setting the sample height
The sample thickness influences the geometrical dimensions of the acquired image. With
the same elongation of the scanner tube, a thicker sample will move to a larger distance
from the probe in the XY plane (Fig. 3-5) thus increasing size of the image.
To account for this effect, the height of the sample above the scanner should be taken
correctly.

When defining the sample thickness, be careful not to miss thickness of the sample used
for XY calibration of the scanner.
To define the sample height, perform the following steps:
1. Open the Scanner Calibration Setup dialog (Fig. 3-6) by selecting the Main menu
command
Settings Calibrations Change Calibrations.
