8.4 SET
Four different SET modes are available for rapid controlled titrations to a
preset endpoint; they differ only in the measured quantity or the measuring
mode:
SET_PH* measured quantity pH
SET_U* measured quantity mV
SET_UPOL* measured quantity µA (selectable pol. voltage in mV)
SET_IPOL* measured quantity mV (selectable pol. current in µA)
The following information applies to all SET modes. Any discrepances are
noted.
SET_PH* Titration to preset endpoint
Reagent Sensor
Concentr. Meas. input A1
Dos. drive A1
applies to ⇒ SET_PH*, SET_U*, SET_UPOL*, SET_IPOL*
SET modes create the same system variables as DET modes, see page
128. In addition the following variables are provided for calculating a drift
volume reduction (see page 154):
DOD Dosing duration during the titration, cumulative
ITD Time duration between conditioning and titration
Assignment parameters for SET modes:
The assignment parameters (Comment, Reagent, etc.) for the SET modes
are the same as those for the DET modes, see page 129f.
8.4.1 Specific parameters for SET modes [* Param ]
The specific parameters for the respective SET mode can be found under
the softkey [* Param ].
