The possible pH end value input ranges from 0.000 to 14.000.
The possible mV end value ranges from -2000 to +2000.
The range of the µA input can be selected between 0.0 and 100.0.
Automatic detection of the equivalence point (EQ) can be switched on and off for linear or dynamic
titration.

If automatic EQ detection is off, titration will continue to the predefined end value in mV or pH or to the
maximum ml value, respectively. Nevertheless, it is possible to calculate the EQ subsequently on the
basis of the recorded measurement data.
If EQ detection is activated, you can define the slope value for the EQ:

The determination of the equivalence point (EQ) is done on the basis of the maximum of the first
derivation (red curve) of the measurement data.
Setting of the maximum titration volume should always make sense. It also serves as a safety
criteria to prevent excessive titration, i.e. a possible overflow of the titration vessel. The maximum
titration volume can be set between 1.000 und 999.999 ml:
