Dynamics
The control range defines the measured value range before the specified
control point. This control point has a vital influence on the titration rate
and thus also on the measuring accuracy.
The values that are actually measurable may vary from the values specified
here, depending on the hardware. The binding measurement value ranges
can be found in the "Technical specifications" chapter for the control
instrument used.
Measuring mode pH:
Input range 0.001 to 20.000
Default value 1.000
Selection off
Measuring mode U:
Input range
0.1 to 2,000.0 mV
Default value 60.0 mV
Selection off
Max. rate
The maximum permissible rate at which dosing takes place.
Rule of thumb for the maximum rate in mL/min:
0.005 · expected reaction rate in µL/min
Input range 0.01 to 166.00 mL/min
Default value 0.75 mL/min
Selection maximum

The maximum dosing rate depends on the cylinder volume (see chap-
ter 32, page 492).
Min. rate
The rate at which dosing is carried out at the very beginning of the titra-
tion and in the control range at the end of the titration. This parameter
has a decisive influence on the behavior at the control point. The mini-
mum rate also has a decisive influence on how exactly the control point
can be kept constant. The smaller the selected minimum rate, the longer it
takes until the control point is reached for the first time.
The following rule of thumb should be considered in order to obtain a
dosing at the control point as constant (regular) as possible:
Min. rate in µL/min = 0.1 · expected reaction rate in µL/min
Input range 0.01 to 9999.00 µL/min
Default value 10.00 µL/min
