Two-point calibration
Calibrating rel. cell constants, temperature coefficients, and TC-curves

The zero point and slope of the measuring characteristic curve are determined
with the aid of 2 measurings of 2 different reference solutions.
Two test solutions with defined values of the respective process variable are
needed as a references.
The calibration routines for conductivity measuring with the universal input cor-
respond to those for the Ci calibration.
