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 29.6.3,
page 347) always lead to a stop, even if the stop criterion has not been
reached.
Selection drift | time | rel. drift | off | drift & time
Default value drift & time
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.
drift & time
The titration is stopped when the stop drift has been exceeded during
the time set and the endpoint has been reached.
Stop drift
This parameter can only be edited with Stop criterion = drift or drift &
time.
The titration is stopped when the endpoint and the stop drift have been
reached.
Input range 1 - 999 µg/min
Default value 15 µg/min
Delay time
This parameter can only be edited with Stop criterion = time or drift &
time.
When the endpoint has been reached, the specified time is allowed to
elapse after the last dosing and the titration is then stopped.
Input range 0 - 999 s
Default value 40 s
