Response Time
The response time can be configured. The following step response times apply
(in accordance with DIN EN 61298-2) when damping is switched off:
Tank height
< 20 m (66 foot)
Sampling rate
-1
1 s
Response time
< 3 s
In accordance with DIN EN 61298-2, the step response time is the time following an abrupt
change in the input signal up until the changed output signal has adopted 90 % of the
steadystate value for the first time.
