The shield is connected to the case.
Ensure that no moisture can enter at the cable end.
Functional check
The output signal must be proportional to the mass. If this is not the case, this may
indicate a damaged measuring cell. In this case, see chapter "9. Faults".
When weighing a gas cylinder make sure that the gas cylinder scale is
seated on a solid and level base and that it cannot catch on any other
objects.
