Description of Sensor Parameters
8.4.9
Operating Temperature
With disabled temperature compensation (see "Temperature compensation" parameter), the
operating temperature specified here is used to calculate the object distance from the
measured sound propagation time. You can specify a value within the allowable value range.
8.4.10
Foreground Suppression
You can use the "Foreground suppression" parameter to define an area in front of the sensor
where all received echoes are ignored. The range extends from the transducer surface of the
sensor up to the distance value specified by this parameter.
By default, the value is set to <End of dead band>.
8.4.11
Background Suppression
You can use the "Background suppression" parameter to specify a range in which incoming
echoes are discounted. When doing so, the input value represents the start of this range and
therefore represents the distance from which all incoming echoes are discounted.
Note!
This parameter is visible in the DTM advanced view.
