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 when Stop criterion = drift or drift &
time.
The titration is stopped when the endpoint and the stop drift have been
reached.
Range 1 ... 999 µg/min
Default value 15 µg/min
Delay time
This parameter can only be edited when 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.
Range 0 ... 999 s
Default value 40 s
Relative stop drift
This parameter is can only be edited when 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.
Range 1 ... 999 µg/min
Default value 5 µg/min
2.2.2 Titration parameters
Under [Titration parameters], the parameters influencing the sequence
of the entire titration are defined.
Pause
Waiting time, for example for dissolving a sample. During this time no
bromine is generated.
Range 0 ... 999999 s
Default value 0 s
