Firstly, enter the offset distance (OSD). If the directions of
P1-A0 and P0-P1 are the same then the distance is positive,
otherwise it is negative.
Press „ENT‟ or soft key „Enter‟ to save setting and enter
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 page of „Offset(dist2)—End‟
After the measurement, press „ENT‟ and he instrument is
now displaying the coordinate of the measured point.
If the measured point is A0, then the target height should
be 0. If the coordinate of A1 is wanted, please enter the target
height ahead depending on facts.
8.4 Plane Offset Mode
The plane offset mode is specifically adequate for
measurement of points that cannot be measured with its
horizontal distance. e.g Measuring the distance or coordinate of
a ridge of a plane.
Firstly, measure any three points (P1, P2, P3) to define the
measured plane. Aim at the measuring point P0, then the
instrument will calculate and display the coordinate of
intersection of the defined plane and the collimation axis. i.e
the coordinate of P0.
