Commands 407
Commands
Depending on the measured value one of the following two KFT commands can
be chosen:
• KFT Ipol
Voltametric measurement with selectable polarization current (measured
value voltage U).
• KFT Upol
Amperometric measurement with selectable polarization voltage (measured
value current I).
KFT Ipol
Command for coulometric Karl Fischer Titrations with voltametric measurement
(selectable polarization current).
Devices
This command can be executed with the following devices which have the KFT
mode:
Titrino: 720, 736, 751, 758, 784, 795, 799
Titrando: 835, 836, 841, 857
Appearance
The command has the following appearance:
without conditioning with conditioning
Parameters
The parameters for the command KFT Ipol 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 defin-
ing the conditions which have to be met at the start of the titration.
• Control parameters
Control parameter for the endpoint (measured value for the endpoint, titra-
tion 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.
• Additional measured values
Definition of additional measured values of other measuring commands
which are saved as additional column in the list of measuring points.
