4.6.4.3 Linear titration
If linear titration control was selected, you have to define the step size (Fig. 97).
Fig. 97
Linear step size can be set from 0.0005 to 5.000 ml (Fig. 98)
Fig. 98
Linear step width can also be set for End-Point titration (pH, mV and dead stop).
In this type of titration, linear step width is used after the first continuous titration stage.
4.6.4.4 Titration direction
The titration direction can be set to «increase» or «decrease» (Fig. 99).
Fig. 99
Example:
increase
decrease
total acidity titration to a pH value of 8.1 using NaOH
titrating for the alkalinity ("m value") to a pH value of 4.5 using HCl
