7.3.3 Plane Offset Measurement
Measuring will be taken for the place where direct measuring can not be done, for example distance or
coordinate measuring for a edge of a plane.
Three random points (P1, P2, P3) on a plane will be measured at first in the plane offset measurement
to determine the measured plane. Collimate the measuring point (P0) then the instrument calculates
and displays coordinate and distance value of cross point between collimation axis and of the plane.
