• When using a reflecting prism equipped with a target for distance and angle measurements, be sure
to direct the reflective prism correctly and sight the center of the prism target accurately.
• Each reflective prism has its own prism constant value. When changing prisms, be sure to change
the prism constant correction value.

Reflecting Prism System (AP Series)
Use an appropriate system for DX.
The figure on the right is an example.
Because all reflecting prisms and accessories
have standardized screws, it is possible to

Prism (ATP1)
This column-shaped prism reduces the possibility
of "losing" the prism during Auto Tracking
measurement.
3D positioning accuracy (standard deviation):
3mm (Horizontal acceptance angle: 360° (full
transit). Angles of elevation and inclination both
less than 20°)
