68 Reference Plane
Reference Plane is used to measure points in reference to a
defined plane.
The plane is defined by 2-10 points. Two points define a vertical
plane. If more than 3 points are used a least squares adjustment is
calculated.
Points are calculated by intersection of the line of sight with the
determined plane. The coordinates are updated with telescope
movement. If a distance is measured to a point, the deviation of
this point from the plane is also displayed.
The plane can be determined in the instrument coordinate system
or a local coordinate system can be set by entering local
coordinates for the first point. All measured points are calculated in
the selected system.
Introduction
Basic Procedure The first step is to define the plane using 2-10 points. The
coordinate system is selected in the Main Menu.
Before starting Reference Plane:
If
Instrument Coordinates are used, the station must be setup and
oriented.
