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).
• MET Upol
Amperometric measurement with selectable polarization voltage
(measured quantity current I).
•
MET pH
Command for Monotonic Equivalence Point Titrations with potentiometric pH
measurement.
