29.3 Endpoint titrations (SET) ￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭
Temp. measurement
Type of temperature measurement.
Selection
Default value continuous automatic
| automatic | off continuous
A temperature sensor must be connected. The temperature is measured continuously.
automatic
If a temperature sensor is connected then the temperature will be measured continuously. Otherwise, the temperature entered manually will be used (see dialog of the titration and measuring parameters).
off
The temperature will not be measured. The temperature entered manually is used (see dialog of the titration and measuring parameters).

Titrant
Selection of the titrant from the titrant list. We recommend always selecting the titrant. This ensures that the correct data (titer, concentration, etc.) is always used for the calculation. Titrants are defined under System ▶ Titrants . You can also enter a name which is not contained in the titrant list. When a determination is started there is a check whether the solution is contained in the list.
For buret units with integrated data chip, a check is made in the method run to verify whether the correct titrant has been attached and whether the type of dosing drive matches. For buret units without an integrated data chip, the cylinder volume and the type of dosing drive are checked.
For the selected titrant, the validity of the titer, the working life of the titrant and the time interval for the GLP test of the buret unit are checked at the start of the determination.
Selection
Default value
Selection of configured titrants | not defined not defined not defined
No check takes place.
