Titration rate
Three predefined sets of parameters can be selected for the titration rate.
Selection slow | optimal | fast | user
Default value optimal
slow
For samples with a low water content or samples which release their
moisture only slowly.
optimal
For all standard titrations. The parameters have been optimized for the
most frequent applications.
fast
For uncritical samples with high water content.
user
The individual titration parameters can be modified.
The settings of the individual titration rates are listed in table 1, page
55.
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 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.
Measuring mode Ipol:
Input range
0.1 - 1250.0 mV
Default value 100.0 mV
