Temperature

Manually entered titration temperature. If a temperature sensor is connec-
ted then the temperature will be measured continuously. This value is
used for temperature correction in pH measurements.

Input range

–20.0 - 150.0 °C

Default value

25.0 °C

Sensor

Selection of the sensor from the sensor list. The selection depends on the
measuring mode. Sensors are defined under System

Sensors.

Selection

Selection of configured sensors

Solution

Selection of the solution from the solution list. We recommend always
selecting the solution. This ensures that the correct data (titer, concentra-
tion, etc.) is always used for the calculation. Solutions are defined under
System

Solutions.

For buret units with integrated data chip, a check is made in the method
run to verify whether the correct solution has been attached and whether
the type of dosing drive matches. For buret units without integrated data
chip, the cylinder volume and the type of dosing drive are checked. The
validity of the titer is checked for the selected solution at the start of the
determination.
