MET
Command for Monotonic Equivalence Point Titrations ( MET ).
Principle
With this command titrations with reagent addition at constant volume increments
are carried out. Measured value acceptance is drift-controlled (equilibrium titra-
tion) or after a waiting period. Equivalence points are evaluated automatically.
Note
This command is suited for titrations with relatively high signal variations or sud-
denly occurring potential jump and for slow titrations or slowly responding e-
lectrodes.
Commands
Depending on the measured value one of the following four MET commands can
be chosen:
• MET pH
Potentiometric pH measurement with pH electrodes (measured quan-
tity pH).
• MET U
Potentiometric voltage measurement with metal electrodes (measured
quantity voltage U).
• MET Ipol
Voltametric measurement with selectable polarization current (meas-
ured quantity voltage U).
