Median
S
The Median Filter (MDN) reduces noise on the measuring signal . The filter
level can be adjusted from 7 up to 13 or switched off .
Moving Average
S
Moving average filter (MAV) smooths out short-term fluctuations . The value
can be adjusted from 1 to 200 measuring periods .
The delay is calculated:
Delay [s] = ( MAV – 1) x T
The time (T) is given by the adjusted excitation frequency of the meter .
Excitation frequency [Hz]
T = Time for filter delay (s)

For example: MAV = 20 and the excitation frequency is 6 .25 Hz
means T=0 .08 s, the delay is 1 .52 s .
Display
S
Moving average filter smooths out short-term fluctuations only for the
display . The value can be adjusted from 1 to 200 measuring periods .
