4 DISTANCE MEASUREMENT
6 Measure the second and third points in the same
way.
Collimate
P2
[F1]
Collimate
P3
[F1]
The instrument calculates and displays coordinate
and distance value of cross point between
collimation axis and of the plane. *1),2)
7 Collimate the edge (P0) of the plane. *3) ,4)
Collimate
P0
8 To show the slope distance (SD), press the [ ]
key.
Each time pressing the [ ] key, horizontal
distance, relative elevation and slope distance are
shown in sequence.
To show coordinate of point P0, press the [ ]
key.
9 To escape the measuring, press the [F1](EXIT)
key. The display returns to the previous mode.
*1) In case the calculation of plane was not successful by the measured three points, error displays. Start
measuring over again from the rst point.
*2) Data display is the mode beforehand of offset measurement mode.
*3) Error will be displayed when collimated to the direction which does not cross with the determined plane.
*4) The point height of the target point P0 is set to zero automatically
