Automatic detection of the equivalence point (EQ) can be switched on and off for linear or dynamic titration
(Fig. 161).
Fig. 161
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 (Fig. 162).
Fig. 162
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. The slope value (dmv/dml) can be read on the printout. It is put between
brackets to the right of the EQ value.
