28.4.3 Rate evaluation (EVAL RATE)
The rate evaluation provides the median dosing rate in a defined range
(so-called window). The median dosing rate is determined by means of lin-
ear regression through a minimum of three measuring points. If the dos-
ing is carried out with only one dosing device and if more than one cylin-
der volume is dosed, then the median dosing rate will be reduced as a
result of the filling time.
When the command is opened for the first time, a window over the entire
time range is already defined. In contrary to the potentiometric evaluation
of a DET/MET titration the individual windows may overlap. A maximum
of 9 windows can be defined.
