10) The antenna ring and connection plug must be fixed.
11) Each type of irregular stress (bending moment, lateral or longitudinal force, exceeding nominal (rated) torque) can only be
permitted up to its specified static load limit provided none of the others can occur at the same time. If this condition is not met, the
limit values must be reduced. If 30% of the bending limit moment and lateral limit force occur at the same time, only 40% of the
longitudinal limit force is permissible and the nominal (rated) torque must not be exceeded. The permissible bending moments,
longitudinal forces and lateral forces can affect the measurement result by approx. 0.3 % of the nominal (rated) torque. The load
limits only apply for the nominal (rated) temperature range. At temperatures <10 C°, load limits are expected to reduce by up to
30%, because there is an increased reduction in toughness as temperatures fall.

13) Static and dynamic.
14) The nominal (rated) torque must not be exceeded.
