The selection of quantities on the Y-axis:
M. value pH, mV or µA (depending on
mode)
Volume i.e. volume against time
Temp. only for automatic measurements
MV, Temp measured value and temp.
combined
dMV/dV measured value derived from
volume
dMV/dt measured value derived from time
dV/dt added volume derived from time
MV,dMV/dV measured value, and measured
value derived from volume,

shown,combined
Quantity X_Axis
Representation size on the X-axis
Volume | time
Titration curves can be shown against volume or time.
Presentation on the time axis is only possible if time
recording (see page 150) has been switched on.
Scale
type of axis scaling
auto | fixed
Both axes of the curve can be scaled automatically by
the Titroprocessor. If a fixed scale is required then it is
essential that all scale parameters are entered (see
below).

Limiting values of fixed axis scales
Y-axis:
pH -20…20 | -2000…2000 mV
-200…200 µA | ERC 0…200
X-axis: 0…999.99 mL | 0…999 999 s
The limiting values of the axis scales can be set at will
within the particular measuring range. Fixed limiting
values are only effective if the scaling has been set to
'fixed'.
Division
Distance between the divisions on the X-axis
0.01…1…99.9 mL/cm
0.01…30…99.9 s/cm
The scale divisions of the X-axis only apply to the
printout of the titration curve.
