7.4.7 AutoTemp
The AutoTemp function controls the automatic start of the measurement after
checking the temperature adaptation.
The pretemperature regulation to the precise incubator temperature is
recommended but not essential. Recommendation: e.g. regulate the tempera-
ture of the sample for BOD5 measurements from 15 °C up to 20 °C.
You can tightly close the sample bottle with the measuring head immediately
and start the measurement. The
AutoTemp function then automatically triggers
the start of the actual measuring after checking the temperature adaptation.
The measuring time of the
AutoTemp phase (adaptation phase plus the test
phase) is added to the sample measuring time selected in the settings.
Pretemperature
regulation of the
sample
With the AutoTemp function switched on and, adhering to the recommendation
according to the table, the error quota that results from the temperature adap-
tation of the sample to the incubator temperature, T
Incubator
, is smaller than 1%
of the selected measurement range final value.
