value is displayed and continuously updated after the next cycle is
finished.
Duration
Depends on the settings in the
Measuring interval
menu.
Note
The WTW background correction procedure is used to determine the
concentration taking into account the color of the sample.

– The heating of the
digestion reactor switches
off.
– The cooling fan switches
on.
Digestion, Treactor = ... °C
6
– When T is < 50 °C, the
valves on the digestion
reactor are opened and the
sample is pumped on to
the photometer.
– The C and D reagents are
added.
Reaction
9
– After a waiting period, the
absorbance is measured
and the concentration is
calculated.
