Note
Evaluation of the value even when the option is disabled
If you enable one or both options and configure a value and then disable the option later, the
grayed out value is nevertheless evaluated.
To disable the two options, delete the previously configured values limit values from the input
boxes and then disable the relevant option.
Recommendation for quickly fluctuating analog values:
If the analog value fluctuates quickly, it may be useful to smooth the analog value first if limit
values are configured.
