Measuring mode Upol:
Input range
0.01 - 125.00 µA
Default value 10.00 µA
Selection off
Max. rate
This parameter is visible only when Titration rate = user.
Rate at which dosing is carried out outside of the control range. The maxi-
mum dosing rate depends on the cylinder volume (see Chapter 10.1.1,
page 70) .
Input range 0.01 - 166.00 mL/min
Selection max.
Default value max.
Min. increment
This parameter is visible only when Titration rate = user.
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 0.1 - 99.90 µL
Selection min.
Default value min.

Stop criterion
The titration is stopped when the endpoint has been reached and this
stop criterion has been fulfilled. If no stop criterion has been selected then
the titration will not be stopped. The stop conditions (see Chapter 7.1.5,
page 58) always lead to a stop, even if the stop criterion has not been
reached.
