Tracking functions:

The laser plane is automatically centred to the receiver “on-grade”

  • Vertical: in both X and Y axis
  • Horizontal: one axis X or Y, other axis horizontal self-levelled
  • For highest demands: exact monitoring of the tracked axis by continuous radio link between rotating laser and receiver. This application requires the use of a 2nd receiver for height checking work. Zonal control with electronic beam screen svoids spurious measurements caused by crossing laser planes and refl etions - increases site safety indication of grade value in % after completion of tracking process shown on the instrument and remote control display.

Slope functions:


  • Digital grade setting of X and Y axis up to ±10 %
  • Manual slope setting of X and Y axise


  • Direction of X axis can be set up to ±10 % with Y axis self-levelled
  • Direction of X and Z axis can be set manually

Last tracked or keyed in grade value is retained after switching off and is retrievable from the memory (both X and Y axis).
