If the marking point of the receiver is located above the laser beam, a fast pulsed signalling tone will
sound and upper LED will flash.
Move the receiver downward accordingly.
If the marking point of the receiver is below the laser beam, a slow pulsed signalling tone will sound and
lower LED will flash.
Move the receiver upward accordingly.
If there is a constant signalling tone and / or the green LED is visible, the marking location is exactly
aligned with the laser beam.
Use a pen to mark the height of the laser beam at the marking locations. The receiver can be aligned
vertically with the help of the tube vial, when the marking points on the left and right sides are at the
same height.
7.5 Applications
7.5.1 PROTON
The PROTON is an easy to use, self-leveling laser device which can be used by one or more people to
perform accurate horizontal measurements with the help of a receiver device. The aim is to describe a
possible application in greater detail, using the construction operation as an example.
Building construction
1. The device height (HI) is the height of the laser
beam.
2. It is determined by adding the measuring
rod reading to a height marking or a known
elevation.
3. Set-up of the laser and positioning the measu-
ring rod with the receiver on a known height or
reference peg (NN).
4. Align the receiver to the position „At height“ of
the laser beam
5. Add the measuring rod reading to the known
NN height to determine the laser height.
