9.3 Plane Offset Measurement

Sometimes we wish to obtain the coordinate of some points where we cannot measure
distance. Fortunately, we can measure the distances of another points, and all these
points are in a plane. in this time the plane offset measurement can be used. the figure is
shown as follow:
1.Select the function of 【angle offset Measurement】

.
2. Start EDM , if you need the coordinate of A0
you should set the height of prism to zero. if you
need the coordinate of A1 you should set the height
of prism to the real height.
3. The result of the point positioned prism is shown
as the picture on the left. Press F4:【Enter】
4.582
4.567

4. The result of the target point appear. if you wish
to display coordinate then you must press
4.565
【CORD】 ,or if you wish display distance then you
1.150
0.871
must press【DIST】.
