For unattended sampling applications, selection of 8 at the Number of Samples to Average
prompt results in a somewhat different data processing sequence. In this case, the 6000
UPG will
take 8 turbidity readings 4 seconds apart at the time the unit wakes up to record a reading. The
software will calculate a simple average of these 8 readings and log this value to memory when
the final measurement of all parameters is complete. The disadvantage of this approach is that
the turbidity sensor will be activated for a longer interval during deployments and this, in turn,
will result in a shorter battery life. However, as for the discrete sample treatment, the advantage
of the data processing is a much more stable sequence of logged turbidity readings which are
likely to better reflect the overall cloudiness of the water being monitored.
Experience will allow the user to be better able to determine whether any averaging sequence is
appropriate for the particular sample in question, and, if so, how many samples to average for the
output or logged values.
See Appendix H for additional practical information on the measurement of turbidity with the
6000
UPG.
