4.6 Measured value damping (dAP)
The damping time enables to set after how many seconds the output signal has
reached 63 % of the final value if the flow value changes suddenly� The set damp-
ing time stabilises the outputs, the display and the process value transfer via the
IO-Link interface� The signals [UL] and [OL] (→ 13 Fault correction) are defined
under consideration of the damping time�
