900 Touch Control
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
device used.
Measuring mode pH:
Input range
0.001 - 20.000
Default value 2.000
Selection off
Measuring mode U and Ipol:
Input range
0.1 - 2,000.0 mV
Default value 100.0 mV
Selection off
Measuring mode Upol:
Input range
0.01 - 200.00 µA
Default value 10.00 µA
Selection off
Max. rate
Rate at which dosing is carried out outside of the control range.
Input range 0.01 - 166.00 mL/min
Default value 10.00 mL/min
Selection maximum

The maximum dosing rate depends on the cylinder volume (see Chap-
ter 32, page 488).
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. This parameter has a
decisive influence on the titration rate and thus also on the accuracy. The
smaller the selected minimum rate, the slower the titration.
Input range 0.01 - 9999.00 µL/min
Default value 25.00 µL/min
