9.5 Column Offset Mode
This function is for measuring the coordinates of column
center and column radius.
Firstly, you should measure the azimuth angle and coordinate
of ‘P1’ on the cylinder under this mode. Then calculate the
horizontal distance, azimuth angle and coordinate of the cylinder
by measuring the surface points of tangency edge1 and edge 2.
If you want to calculate just measuring the azimuth of edge
1, you need to let the line between instrument center and point
p1 through the column center.
