Measurement optimization

5.6.1 P20 Damping Time
FACTORY DEFAULT: 40
Damping time reduces unwanted fluctuations in displaying the measured data (e.g., ripples). If the level jumps, the transmitted value
reaches 98% of the jump at this time. Unit: second (s). Value range: 0...999 s.

Damping time = 10 s
Level change (level) = 2 m (6.6 ft)

2 s
> 10 s
Damping time = 40 s
Level change = 2...3 cm (0.39"...0.79") ripple If a higher degree of
undulation is expected in the measured liquid column, it is
recommended to set a higher damping time. This way, the
fluctuation of the value of the transmitted level can be reduced.
