8.3 MET
There is a choice of four different MET modes for controlled titrations with
fixed volume steps. They differ only with regard to the measuring quantity:
MET_PH* Measuring quantity pH
MET_U* Measuring quantity mV
MET_UPOL* Measuring quantity µA (adjustable pol. voltage in mV)
MET_IPOL* Measuring quantity mV (adjustable pol. current in µA)
The following information applies to all MET modes. Discrepancies are indi-
cated.
MET_PH* monotonic equivalence point titration
Reagent Sensor
Concentr. Meas. input A1
Dos. drive A1
applies for ⇒
MET_PH*
, MET_U*, MET_UPOL*, MET_IPOL*
MET modes create the same system variables as DET modes, see
page 129.
Assignment parameters of the MET modes:
The assignment parameters (comment, reagent … etc.) of the MET modes
coincide with those of the DET modes, see page 130f.
8.3.1 [ * Param ] Specific parameters for MET modes
The specific parameters of the corresponding MET mode will be found un-
der the [* Param ]softkey.
