The device will then return to measurement mode, or it will display an error
message if necessary.
The resulting relative cell constant is briefly shown and can always be viewed
in the "SEt ConF" menu under the parameter "CELL Corr".
This function enables the user to automatically calibrate the relative cell con-
stant with a selection of standard reference solutions.
