4 DISTANCE MEASUREMENT
4.7.2 Distance Offset Measurement
Measuring distance and coordinate of the center of a pond or a tree of which the radius is known.
Measuring the distance or coordinate till P0 point, input oHD value as an offset value and measure P1
point showing as following draw in distance offset measurement. The display shows distance or
coordinate value until P0 point.

oHD < 0
oHD >0
In case the measuring point of (P1) is front side than that of requiring
point of (P0), the offset value shall be plus, and if it is rear side, the
offset value shall be minus.
Occ. Point
● When setting the coordinate value for the occupied station, refer to Section 5.1 “Setting Coordinate
Values of Occupied Point”.
