900 Touch Control

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 µg/min

Default value

5 µg/min

Titration parameters

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

Pause

Waiting time, for example for dissolving the sample. During this time no
bromine is generated.

Input range

0 - 999999 s

Default value

0 s

Extraction time

Minimum duration of the titration. The titration will not be stopped during
the extraction time, even if the endpoint has already been reached. The
titration is however stopped if a stop condition is fulfilled during this time
(see Chapter 29.6.3, page 347).

Input range

0 - 999999 s

Default value

0 s

Temperature

Temperature entered manually. The temperature is being continuously
measured when a temperature sensor is connected and when Temp.
measurement
= automatic or continuous is defined (see sensor dialog
of the command).

Input range

–20.0 - 150.0 °C

Default value

25.0 °C

Time interval MP

Time interval for entering a measuring point in the measuring point list.
The measuring point list is limited to 1000 measuring points.

Input range

0.1 - 999999.0 s

Default value

2.0 s
