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,
combined

all

all curves which can be
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 151) 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.
