This exercise illustrates the use of
markers.
A total of four normal markers can
be placed on the graphical display.
The placement of the markers is
limited to the calibration points.
If there are 11 calibration points
then the markers can be placed on
each of the vertical graticule lines.
Each of the normal markers can
be changed to delta markers. For
example, marker 2 will change to
marker 2 and 2R where 2R is the
reference and 2 would be the delta.
