Measurement
Filter
S
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) × T
The time (T) is given by the adjusted excitation frequency of the meter.
Excitation frequency [Hz] T = Time for filter delay (s)
15 0.03333
12.5 0.040
7.5 0.06666
6.25 0.080
3.75 0.13333
3.125 0.160
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.
For calculation of the delay see Moving Average above.
