4.4 Calibration functions
4.4.1 Determining cell constants
Only the change in conductivity is measured an evaluated during the
Rancimat measurement. As a result, the cell constants of the conductivity
measuring cells used in the Biodiesel Rancimat, which are normally in the
range from 1.00...1.20, only have to be entered exactly if the absolute
conductivity measured value is to be displayed correctly.
The value also has to be entered before carrying out the GLP test "Con-
ductivity". The cell constants can thereby be entered manually or deter-
mined automatically using a defined standard solution (see Optional
accessories, page 180).
Entering cell constants manually
Proceed as follows if you wish to enter the cell constants manually:
