Enter the „Offset(dist2)—distance‟ page through the offset
menu.
Firstly, enter the offset distance (OSD). If the directions of
„P1-A0‟ and „P0-P1‟ are the same, the distance is positive,
otherwise it is negative.
Press „ENT‟ or the soft key „Enter‟ to save settings and enter
the page of „Offset(dist2)-begin‟. To measure the point, you must
aim at P0 as shown above.
After the measurement, press „ENT‟ to end the dialogue and
enter the page of „Offset(dist2)—End‟
After the measurement, press „ENT‟ and the instrument is
now displaying the coordinate of the measured point.
◆
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.
8.4 Plane Offset Mode
Sometimes we wish to obtain the coordinate of some points
where we cannot measure distance directly . Fortunately, we can
measure the distances of another points, and all these points are in
a plane. At this time the plane offset measurement can be used.
Firstly, you can measure any three points (P1, P2, P3) to
define the measured plane. Then ,you can aim at the measuring
point P0, and the instrument will calculate and display the
coordinate of intersection of the defined plane and the collimation
axis. i.e the coordinate of P0.
