For the solutions listed above, the Transmitter can determine the sub-
stance concentration from the measured conductivity and temperature
values in % by wt. The measurement error is made up of the sum of
measurements errors during conductivity and temperature measure-
ment and the accuracy of the concentration curves stored in the
Transmitter.
We recommend to calibrate the Transmitter together with the sensor.
For exact temperature measurement, you should perform a tempera-
ture probe adjustment. For measuring processes with rapid temperature
changes, a separate temperature probe with fast response should be
used.
When measuring processes such as dilution or intensification of CIP
solutions (Clean-In-Place), it is helpful to switch between the parameter
sets for measuring the process medium and for measuring the CIP solu-
tion.
