CAUTION
Although the output signal is still in the range -10 ... +10V, force can still be
present after a RESET. The addition of further loads can lead to an overload
and therefore damage to components and danger to persons.
Make sure that the force transducer is not overloaded, even if the output signal
is still in the -10 ... +10V range.
