Measuring lines
A minimum of 2 points are required to measure a line. A maximum of
100 points can be probed and will be processed by a fit algorithm to
define the line.
 Press the Line Measurement key. The Probe Line
screen will be displayed. Press the key twice to
measure a series of lines using auto repeat.
 Move the stage to position the crosshairs over an end
