- The supporting construction of the scale (and thus the load cells) and the vessel must
be stable enough to withstand the specified loads, horizontal (check with spirit level!)
and flat.
- Vessels should preferably be suspended by 3 load cells (see figure).
This minimizes the interference between pendulum movement and rotation and
ensures uniform load distribution.
- Transverse and/or horizontal forces and torques exceeding the permissible limits are
disturbances which can generate measuring errors and, in the worst case, may
damage the load cell.
- If the object to be measured is constrained properly, damage and measuring errors
can be prevented without affecting the required space for movement in the direction
of the measurement.
Consideration should be given to the fact that thermal expansion and contractions
may constrict the required space for movement of the object to be weighed and
could thereby lead to significant falsification of the measuring results.
Therefore, special attention should be paid to the design, arrangement, and
condition of the constrainers.
