14.2 Averaging
The average of a measured value is needed for various applications.
e.g. Smoothing a widely fluctuating measured value (e.g. wind, pressure, etc.)
Average flow velocity in a ventilation conduit
Hourly or daily average values for weather data (temperature, wind, etc.)
Also for consumption values (electric current, water, gas, etc.)
The average value
M
of a measured value is obtained by
adding together a series of measured values (M
i
) and
then dividing this total by the number of measured values
used (N).
If, in function selection, averaging is selected, a
new selection menu will appear listing the vari-
ous averaging modes.
These include measured value smoothing for
the selected channel with a sliding average win-
dow, averaging over individual measuring oper-
ations selected by place or time, averaging over
time, over cycles, or over specified measuring
points.

14.2.1 Smoothing meas. values by means of a sliding average
The first averaging method applies exclusively
to the measured value of the selected channel;
this is used to smooth measured values of an
unstable or strongly fluctuating nature, e.g. flow
turbulence, by means of a sliding average over
a specified time frame. The
level of smooth-
ing
can be set in the
Smoothing
function by
specifying the number of measured values to be averaged (range 0 to 99). The
