Measuring mode Upol:
Input range
–125.00 - 125.00 µA
Selection
off
Default value
off
Titration rate
Three predefined sets of parameters can be selected for the titration rate.
Selection
slow | optimal | fast | user
Default value
optimal
slow
For steep titration curves for which dosing must be carried out in small
steps at the endpoint.
optimal
For all standard titrations. The parameters have been optimized for the
most frequent applications.
fast
For flat titration curves for which the endpoint is reached only slowly.
user
The individual titration parameters can be modified.
The settings of the individual titration rates are listed in table 3, page
104.
Dynamics
This parameter is visible only when Titration rate = user.
This parameter defines the control range before the specified endpoint.
Individual volume steps are dosed in the control range, the dosing is finely
controlled. The closer the endpoint, the slower the dosing until the dosing
rate defined under Min. rate has been reached. The larger the control
range, the slower the titration. Outside of the control range, dosing is car-
ried out continuously, and the dosing rate is defined under Max. rate.
