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.
Stop drift
This parameter can only be edited with Stop criterion = drift.
The titration is stopped when the endpoint and the stop drift have been
reached.
Input range
1 - 999 µL/min
Default value
20 µL/min
Delay time
This parameter can only be edited with Stop criterion = 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
10 s
Relative stop drift
This parameter can only be edited with Stop criterion = rel. drift.
The titration is stopped when the endpoint and the sum of the drift at the
start of the titration and the relative stop drift have been reached.
Input range
1 - 999 µL/min
Default value
10 µL/min

Titration parameters
Under [Titration parameters], the parameters influencing the sequence
of the entire titration are defined.
