The individual variables are described in Section 4.5.7. The ERC
(Equivalence point Recognition Criterion) is a measure of the size of
the jump in the titration curve. The ERC found is compared with EP
criterion defined in the method for the evaluation of the titration
curve (see Section 4.1.1). The ERC is therefore an important quantity if
you have to adapt the parameters for the evaluation of the equivalence
points.
Calibration and titrant data
The [Calibration data] and [Titrant data] buttons in the dialog
More determination data/View data are only present when the
determination has been loaded. In these dialogs the sensor data and
titrant data that were valid at the time when the determination was
carried out are shown. The concentration and titer of the titrant can
be subsequently altered here. When a loaded determination is
recalculated (see Section 3.18.8), the values shown here are used for
the variables TITER and CONC (concentration). Thereby, the values
saved under System/Titrants are not changed. The Calibration
data cannot be altered at a later date.

If Messages are produced during a determination sequence then
these will be shown under More determination data/Messages. The
[Messages] button in the dialog Results/ More determination data
is only active when messages have been entered during the run.
