If for rope probes the DC value is less than 7, then measurement is not possible in the area of the straining
weight (0 to 250 mm from end of probe; lower blocking distance).

Reaction time
The reaction time can be parametrized. The fastest possible reaction time is given by the measuring rate:
Probe length
Level measurement
<10 m (33 ft)
3.6 measurements/second
up to 40 m (131 ft)
³2.7 measurements/second
