16 Calibrating Ci conductivity sensors

TC curve (for nonlinear temperature coefficients)
If the conductivity of a liquid whose temperature coefficient changes with tem-
perature has to be measured, this method can determine 5 temperature coeffi-
cients for 5 temperature intervals. In this way, it is possible to determine a good
approximation of the temperature coefficient curve. While the operator brings
the sample solution to the temperature values requested by the device, the de-
vice determines the temperature coefficient for each interval. This requires in-
stallation of a temperature sensor that the device can use to sense the
temperature of the sample solution.
16.2.2 Calibration presets for Ci conductivity sensors
Before you can perform a calibration, you must first enter the necessary calibra-
tion default settings. The possible settings for the Ci calibration are described in
the following.
Open the calibration default settings:
Device menu > Calibration > Select Ci Analysis Input or Universal Input >
Calibration Presets
Conductivity
6 calibration points
5 intervals
Temperature
NOTE!
The "Calibration default settings" menu appears in the Device menu only if a
user with corresponding user rights is logged in.
