maximum
The maximum dosing rate depends on the cylinder volume (see chap-
ter 32, page 492).
Min. increment
Minimum volume increment that is dosed at the beginning of the titration
and in the control range at the end of the titration. This parameter has a
decisive influence on the titration rate and thus also on the accuracy. The
smaller the selected minimum increment, the slower the titration.

Stop criterion
Stop criterion
The titration is stopped when the endpoint has been reached and this
stop criterion has been fulfilled. If no stop criterion has been selected then
the titration will not be stopped. The stop conditions (see chapter 29.4.4,
page 329) always lead to a stop, even if the stop criterion has not been
reached.
NOTICE
In older instructions the delay time was usually defined as the stop cri-
terion. The same delay time may however result in different stopping
time points – because of different smallest possible volume increments
(depending on the cylinder volume). In contrast, if the stop drift is used,
the titration will always be stopped at the same curve slope dV/dt.
