2. Move the machine to the elevation reference point. The
measurement of this point brings the entire plane up or down to
intersect the point and determine its relative elevation.
3. When the sensor is over the point, press

to measure
the elevation reference point (Figure 3-25). The

Creating a Sloping Plane Surface
The sloping plane surface model is composed of four basic factors:
• a mainfall orientation
• a mainfall grade
• a crossfall grade and
• a reference elevation point on the plane.
Just like aligning the rotating laser plane and adjusting the laser
receiver height, the operator needs to be prepared with a set of

If you have the NEZ coordinates for the elevation
reference point, press the corresponding entry box
and enter in the information.
