4 DISTANCE MEASUREMENT
4.7.3 Plane Offset Measurement
Measuring will be taken for the place where direct measuring can not be done, for example distance or
coordinate measuring for a edge of a plane.
Three random prism points (P1, P2, P3) on a plane will be measured at first in the plane offset
measurement to determine the measured plane. Collimate the measuring target point (P0) then the
instrument calculates and displays coordinate and distance value of cross point between collimation
axis and of the plane.
zWhen setting the coordinate value for the occupied station, refer to Section 5.1 “Setting Coordinate
Values of Occupied Point”.
Example: Non-prism measurement
Operating procedure Operation Display
1Press the [F4](P1
) key from distance measuring
mode to get the function on page 2. [F4]
2Press the [F1](OFSET) key. [F1]
3Press the [F3](PLANE OFFSET) key. [F3]
4Press the [F3](NP/P) key to change to the non-
prism mode. [F3]
5Collimate first point P1, and press the [F1](MEAS)
key.
N-time measuring will start.
After measuring, the display will show the second
point measurement.
