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 28.1.4,
page 265) always lead to a stop, even if the stop criterion has not been
reached.
NOTE
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.
Selection drift | time | rel. drift | off
Default value drift
drift
The titration is stopped when the stop drift has been reached.
time
The titration is stopped if the endpoint has been exceeded during a
certain time period (Delay time).
rel. drift
The titration is stopped when the sum of the drift at the start of the
titration and the relative stop drift has been reached.
off
The titration will not be stopped until the stop conditions have been
fulfilled.
