Option 2: Enter the filter length as a numerical value
If the predefined filter lengths are not suitable, an individual filter length can be entered for the
Moving Average and Moving Median filters. Especially when it comes to applications without dy-
namic changes in distances, such as the verification of the position of an object, a greater filter
length can improve the performance of the sensor. You can specify the length of the Moving Av-
erage and Moving Median filters after selecting the Custom filter.
