Description
Filter time constant
dF1
Digital filter
0.0...
0.6...
100.0...
Is used to adapt the digital 2nd order input filter (time in s; 0 s = filter off)
If the input signal changes abruptly, about 26% of the change are captured
after a time corresponding to the filter time constant dF (2 x dF: approx. 59%;
5 x dF: approx. 96%)
When the filter time constant is great:
- Great attenuation of interference signals
- Slow response of actual value display to changes of the actual value
- Low limit frequency (low-pass filter)
