The foundation at the installation location must be capable of safely supporting the weight of
the scale at the support points when it carries the maximum load. At the same time, it
should be so stable that no vibrations arise during weighing operations. This applies also
when the weighing platform is integrated in conveying systems and the like.

Ensure that vibrations due to machines near the installation site are kept to a minimum.
