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

28.1.3

Titration parameters

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

Titration direction

Selection

+ | - | auto
The default value depends on the measuring mode:
Ipol = -, Upol = +

+
Positive measured value modification, i.e. in the direction of a greater
voltage or greater current.
-
Negative measured value modification, i.e. in the direction of a lesser
voltage or lesser current.
auto
The titration direction is determined automatically from the start mea-
sured value and the set endpoint.
