2.7 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 mode.

"**titr." means that these values can be changed dur-

ing the titration. They influence the ongoing determina-

tion. 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.

2.7.1 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 also page 55.

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 32.

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 33.
