Selection drift | time | 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).
off
The titration will not be stopped until the stop conditions have been
fulfilled.
Stop drift
This parameter is visible only when Stop criterion = drift.
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 is visible only when Stop criterion = time.
When the endpoint is 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
7.2.5 Control parameters EP2
Menu ▶ Parameters ▶ Control parameters EP2
The control parameters for the second endpoint are defined under Con-
trol parameters EP2. The parameters and the input ranges are the same
as for the first endpoint.
7.2.6 Stop conditions
Menu ▶ Parameters ▶ Stop conditions
The conditions for stopping a titration are defined under Stop condi-
tions, if this does not occur automatically. This could be the case when
the set endpoint is not reached or if the stop criterion (see "Stop crite-
rion", page 88) is not fulfilled.
Stop volume
The titration is stopped when the specified volume has been dosed since
the start of the titration. This volume should be adjusted to the size of the
titration vessel in order to prevent the contents from running over.
