Actual Value Output Freq.
Left fct. Up fct. Down fct. Right fct.
In case a change of this parameter is needed, consider to change P420 SENSOR RANGE
to the corresponding dimension unit too!
P410 CONF.SENSOR
Sets how the connected sensors are used and which sensor is active.
It is also possible to measure the difference of two connected sensors or to configure an
automatic switch-over in case of a faulty sensor.
