5.1 Dynamic equivalence point titration (DET)
Dynamic equivalence point titration is a titration mode for all standard
titrations with an s-shaped curve progression. The reagent is added in vari-
able volume steps. The volume steps vary as a function of the slope of the
curve. An attempt is made to reach constant measured value changes
with each dosing. The optimal volume for dosing is determined from the
measured value changes of the previous dosings. Measured value accep-
tance is measured value drift-controlled (equilibrium titration) or after a
waiting time. Equivalence points are evaluated automatically.

5.2 Monotonic equivalence point titration (MET)
Monotonic equivalence point titration is a robust titration mode for titra-
tions with any curve shape and for slow titrations or slow-response elec-
trodes. The reagent is added in constant volume steps. Measured value
acceptance is measured value drift-controlled (equilibrium titration) or
after a waiting time. Equivalence points are evaluated automatically.
