NOTE
Select optimal as titration rate when you are developing a new titra-
tion method. This parameter is suitable for virtually all titrations and
only needs adaptation in special cases.
The settings of the individual titration rates are listed in table 7, page
298.
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). This value is used for temperature correction in pH
measurements.
Input range –20.0 - 150.0 °C
Default value 25.0 °C
User-defined parameters
These parameters are only accessible when Titration rate = user.
Volume increment
Volume that is dosed in each dosing step. The choice of the correct vol-
ume increment is a basic requirement for achieving high accuracy. A good
guideline is 1/20 of the expected EP volume. For steep jumps the volume
increment should tend toward 1/100 and for flat jumps toward 1/10 of
the EP volume.
Small volume increments are used for determining blank values or with
very asymmetrical curves.
NOTE
The accuracy of the evaluation cannot be increased by using smaller
increments as the measured value modifications between two measur-
ing points are then of the same order of magnitude as the noise.
Input range 0.00005 - 999,900 mL
Default value 0.10000 mL
Dosing rate
Rate at which the volume increments are dosed.
Input range 0.01 - 166.00 mL/min
