Saving the results of analyses
When you click the right mouse button on the region where the results of analyses are
displayed, the submenu will appear.
If Save Data is selected from the submenu, Save as dialog box will appear, and the all
analysis results displayed on the screen can be saved on the disk file in the text form.

Average roughness (Ra)
The equation used for computing the average roughness Ra stipulated in JIS B0601
has been expanded to apply to a 3-dimensional plane. It is stipulated as the “arith-
metic average of the absolute value of the deviation from the average height Z
0
of
the analysis plane”.
