9.2 Offset measurement
Offset measurement is performed in order to find a point where a target cannot be
installed directly or to find the distance and angle to a point which cannot be
sighted.
It is possible to find the distance and angle to a point you wish to measure by
installing the target at a location a little distance from the target point and
measuring the distance and angle from the surveying point to the offset point. And
if instrument station has been set up, the coordinates of the target point can be
calculated.
There are two offset-measuring methods: distance offset and angle offset.
9.2.1 Distance offset measurement
Finding it by entering the horizontal distance from the target point to the offset
point

When the offset point is positioned to the left or right of the target point, make
sure the angle formed by lines connecting the offset point to the target point
and to the instrument station is almost 90
°
. When the offset point is
positioned in front of or behind the target point, install the offset point on a
line linking the instrument station with the target point.
