5.2.2 Composite sample
It is possible to calculate a composite sample.
Terms A composite sample is the mean value of several single values that
were measured in a specific time window. For example, the mean value
of 08:00 o´clock to 10:00 o´clock is calculated.
The Time shift of sampling start is the daily time shift (in hours) of the
time windows of a composite sample. For example, each day the com-
posite sample is calculated two hours later than on the previous day.
Note
TresCon carries out the calculation required by the ATV (Abwasser-
technische Vereinigung e. V.) itself.
