4Collimate prism P1, and press the [F1](MEAS) key.

Measuring will start.

After measuring, the second point measurement screen will be shown.

5Measure 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)

6Collimate point P0 on the plane using the horizontal motion clamp and horizontal tangent screw.

P0 data will be shown.

7To show the slope distance of point P0, press the [F2](SD) key.

8To show the coordinates, press the [F3](NEZ) key. *3),4)

*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.
