Cell grounding

The TIM870 calculates and displays the κ conductivity based on a G
measured conductance and the K cell constant of the conductivity cell
used.
The K constant (expressed in cm
conductivity cell depending on the cell geometry.
To measure conductivities, you must know the cell constant value.
With the TIM870, you can directly enter K in the Edit electrode menu
( see "Cell constant (parameter)", page
determine K by calibrating the conductivity cell
( see "Electrode calibration (conductivity)", page
Defines the grounding of the measuring cell. Select one of the
following options:
Reference
Grounding is ensured by a reference electrode - general use.
Metal
Grounding is ensured by a metal electrode connected to the GND
socket on the Titration Manager. Use this option in case of high
resistive solutions in order to avoid measuring background noise at
the electrodes.
Others
Grounding is not ensured by the reference electrode and is defined
outside the method.
