4 Titrations
4.1 Monotonic equivalence point titration (MET)
Monotonic equivalence point titration is a titration mode for titrations
with relatively high signal fluctuations or suddenly occurring potential
jumps and for slow titrations or slow-response electrodes. The reagent is
added in constant volume steps. Measured value acceptance is drift-con-
trolled (equilibrium titration) or after a waiting time. Equivalence points are
evaluated automatically.

4.2 Endpoint titration (SET)
Endpoint titration is a titration mode for rapid routine determinations to a
preset endpoint (e.g. titrations in accordance with special norms) and
titrations for which reagent overflow must be avoided. The titration termi-
nation at the endpoint takes place either drift-controlled or after a waiting
period. The volume dosed until the endpoint is used for calculating the
content of the sample.
