Response time
The response time can be configured. The following step response times (as per DIN EN 61298-2)
1)
apply if the damping is switched off:
Tank height Sampling rate Response time
< 5 m (16 ft) 1 s
-1
< 3 s
1) According to DIN EN 61298-2 the step response time is the time which passes after a sudden change of the input signal until the output signal
assumes 90% of the steady-state value for the first time.
