Parameters Control parameters

The control parameters for the endpoint are defined under Control
parameters
.

Endpoint at

Measured value for the endpoint.

Input range

–1250.0 ... 1250.0 mV

Default value

50.0 mV

Selection

off

Note

Note that the parameter Endpoint at is linked with the parameters
Dynamics and I(pol). Explanations in this connection can be found in
chapter 10.4 Control parameters and polarization current, page 95.

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 3, page
77
.

Dynamics

This parameter can only be edited with Titration rate = user.
