First, find on the right-hand scale in the
nomogram the point indicating the
apparent height. Secondly find on the left-
hand double scale the point indicating the
ground point reading. Thirdly, connect
these points. The corrected reading will
be found from the pertinent middle scale
at the point of intersection. In this
procedure the slope angle can be
neglected as the left-hand ground point
scale has been constructed so that both
the ground slope angle and the average
eye level height of 1.6 m [5.5 ft] have
been taken into account.
