the minimum value) of the
measured concentrations
within the selected sampling
time is stored.
The average value of all the
measured concentrations
within the selected sampling
time is stored
Measurements are stored if
they exceed a threshold
beyond the trigger value (rel-
ative to the last stored value).
Measurements within the
sampling time are stored.
Once the capacity of the
data-logger is reached, the
old data are overwritten by
new values.
Once the capacity of the
data-logger is reached, no
