INDEX MARK
By mirroring an index mark into the eyepiece (pendulum position of the compensator) compensation
errors can be eliminated and the accuracy can be increased.
(best accuracy)
Measurements should only be carried out if the black arrow is in the horizontal center of the white line
in the index mark.
Note:
The highest accuracy can only be achieved with the black arrow beeing centered in the white area.
USE OF THE LASER
(only model GFE 32-L)
With the built-in laser beam the target can be aimed at and marked. By focussing the laser dot can be
adjusted. Such, the marking of the target can be acomplished by one person only.
Power on the laser beam with the laser knob.
The smallest diameter of the laser dot will be achieved if the laser beam is focussed.
By means of the laser beam all measuring tasks can be acomplished and will be visualized to the user.
The transmission of the laser dot is exactly adequate to the accuracy indication of the unit GFE 32-L.
