Dynamics pH

Dynamics defines the measured value range before the given endpoint. It
has a decisive influence on the titration rate and therefore on the accuracy.
In the control range, dosing is controlled by the Min. rate. The closer the
endpoint, the slower the dosing until the Min. rate has been reached. The
larger the control range, the slower the titration. Outside the range the dos-
ing takes place with Max. rate (see Chapter 5.6.3.4.2, page 650).

Max. rate

Rate at which dosing is carried out outside of the control range. The max-
imum dosing rate depends on the cylinder volume of the exchange unit or
dosing unit used.

Titrando, 855
Range

0.01 ... 166.00 mL/min

Default value

1.00 (slow), 10.00 (optimal), 166.00
(fast) mL/min

Titrino
Range

0.01 ... 150.00 mL/min

Default value

1.00 (slow), 10.00 (optimal), 150.00
(fast) mL/min

Min. rate

Rate at which dosing is carried out at the very beginning of the titration and
in the control range at the end of the titration. The smaller the selected
minimum rate, the slower the titration.
