4 Collimate prism P1, and press the
[F1](MEAS) key.
Measuring will start.
After measuring, the second point
measurement screen will be shown.

5 Measure the second and third prism in the
same way. *1)
The instrument calculates and displays
coordinate and distance value of cross point
between collimation axis and of the plane. *2)

6 Collimate point P0 on the plane using the
horizontal motion clamp and horizontal
tangent screw.
P0 data will be shown.

*1) In case the calculation of plane was not successful by the measured three points, error displays. Start
measuring over again from the first point.
*2) Error will be displayed when collimated to the direction which does not cross with the determined
plane.
*3) The reflector height of the target point P0 is set to zero automatically.
*4) To repeat the offset measurement, press the [F1](NEXT) key. The display will return to step 4.
