14. Functions menus
smoothed measured value can thus also be used in all subsequent evaluation
functions in combination with averaging over individual measured values (s.
14.2.2).
To smooth a measured value over e.g. 15 values
Smoothing: 15
Sampling rate: 10 M/s
Time constant (s) = Smoothing x Scan time = 3s at a channel
In most D6 and D7-sensors, the moving average is already built into
the sensor. It is configured by entering the averaging time in the sen-
sor menu. The damping is no longer available in this case.
How the averaging menus operate:
The following averaging menus use some of the standard functions
such as averaging mode, output cycle, sampling rate - all appropri-
ately reprogrammed. Data output via the interface or to memory is
possible but this must be configured. To also display the average
value acquired as it is being output a function channel M(t) must be
activated on an additional channel for the sensor in question (s. 15.9).
14.2.2 Averaging over manually selected meas. operations
To obtain the average of individual measuring
operations at particular locations or times select
the menu
Average over meas. operations .
Here individual measuring point scans 'E
i
' can
be initiated manually.
