controlled. The closer the endpoint, the slower the dosing until the vol-
ume increment defined under Min. increment has been reached. The
larger the control range, the slower the titration. Outside the control
range, dosing is carried out continuously, and the dosing rate is defined
under Max. rate.
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 32 Technical specifications chapter, page 355.
Measuring mode 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
Selection maximum
Default value maximum
maximum
The maximum dosing rate depends on the cylinder volume (see Chap-
ter 31, page 338).
Min. increment
Minimum volume increment that is dosed at the 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 increment, the slower the titration.
Input range 0.10 - 99.90 µL
Selection minimum
Default value minimum
