Action to be taken
▶ After the pipes have been laid,
the trench has to be filled in
immediately in order to ensure
temperature stability.
▶ Give the pipes time to accli-
matize before proceeding with
measurement.
▶ Use a blower to blow air through
the pipe so that the air can mix
with and expel the mist/haze.
▶ Cover the pipe to prevent heat
from developing inside the pipe.
▶ Check the inclination of the
pipe.
▶ Secure the target plate in the
holder.
▶ Check the value that was
entered and the unit (% or ‰).
▶ Set up the laser and/or the
target plate in such a way that
the bubble is in the middle of
the spirit level.
