2.6 Parameters, key <PARAM>
The key <PARAM> is used for the entry of values that
determine the modes. Values marked with "cond." are
accessible during the conditioning in the SET and KFT
mode. "**titr." means that these values can be
changed during the titration. They influence the ongo-
ing determination. Other values can only be changed in
the inactive state.
The display texts of the Titrino are shown to the left.
The values are the default values.
2.6.1 Parameters for DET and MET
titration parameters
determine the course of the titration and measured
value acquisition.
stop conditions:
Parameters for the automatic termination of the titra-
tion.
statistics:
Calculation of mean values and standard deviation,
see page 77.
evaluation:
Parameters for the evaluation of EP's, fix EP's, and
pK/HNP.
preselections:
ON/OFF of various auxiliary functions such as auto-
matic requests after the start and activate pulse.

General titration parameters
Measuring point density (0...9)
0 means highest density, 9 lowest. Selection of the
meas.pt.density, see page 21.
Minimum increment (0...999.9 µL)
The increment is dispensed at the beginning of the
titration and in the region of the equivalence point.
Size of volume increment (0...9.999 mL)
Dosing step. Small volume increments are needed to
determine blank values or to assure accuracy with
highly unsymmetrical curves. Selection of size of the
increment, see page 21.
