RELATIVE 0-POSITION (REFERENCE POINT)
Within the range of ± 20 mm of the standard reference point (0-position) a relative 0-position can be
set. Press the „0SET“ button when the laser beam hits the receiving window (the „0SET“ symbol will
flash on the display). This current position of the laser beam is now set as the relative 0-position on the
receiver. Press the „0SET“ button to return to the default mode.
MM INDICATION
If the reference level of the receiver is e. g. 18 mm below the laser beam this height difference will be
