If you specify the starting and end points, a line for
measurement is drawn between them.
5 Draw the second line by specifying two arbitrary points
(C and D on the figure) on the screen.
If you draw two lines, an angle surrounded by two
intersecting lines is shown.
If an angle cannot be measured such as when you specify
the same point for starting and ending points of a line or two
lines are completely parallel, "NG" is displayed.
6 Repeat steps 4 and 5 to continue measuring another
angle.
