Dynamics pH

The control range defines the measured value range before the given control
point. It has a decisive influence on the titration rate and thus also on the
accuracy. The dosing is also monitored by the Min. rate within the control
range. The nearer the control point, the slower the dosing takes place until
the Min. rate has been reached. The larger the control range, the slower
the titration. Outside the control range, dosing proceeds continuously at the
Max. rate.

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. The following rule of thumb should be used as a starting
point for parameterization: Max. rate in mL/min = 0.005 • Expected rate
of reaction in µL/min.
