Low Pass Time Constant: Attenuation of measurement signal in the event of a
stable measurement value
Non-linear filter low pass Time constant: Attenuation of measurement signal upon
measurement value change > than defined threshold
Non-Linear Filter Threshold: The threshold in % of span is relative to the largest
measurement range. It is set so that it is above the peak-to-peak noise of the
measurement signal.
