Parameters
The parameters for the command SET pH are configured in the following 8 tabs:
• General/Hardware
Parameters for devices, dosing devices, sensors and stirrers.
• Start conditions
Parameters for the measurement of the initial measured value and for
defining the conditions which have to be met at the start of the titra-
tion.
• Control parameters
Control parameter for endpoint 1 and endpoint 2 (measured value for
the endpoint, titration rate, user defined parameters, stop criterion).
• Titration parameters
Parameters for the run of the titration.
• Stop conditions
Definitions of conditions which cause the stop of the titration.
• Conditioning
Switching conditioning on/off. Definition of start drift, drift correction
and stop conditions.
• Additional evaluations
Definition of additional methods for evaluation of the titrations curves.
