10.2.10 Selecting and determining the nonlinear temperature
compensation TC nLin4
Preparatory activities The nonlinear temperature compensation TC nLin4 is determined from
several standards of unknown concentration.
You prepare the required standards yourself through equidistant dilu-
tion of the standard with the highest concentration e.g.:
Standard with the high-
est concentration
Volume share in %
Deionized water
Volume share in %
Standard 1 100 0
Standard 2 95 5
Standard 3 90 10
Standard 4 85 15
Standard 5 80 20
1 Highlight the channel of the conductivity measuring cell in the
measured value display.
2 If necessary, select the measured parameter with <MODE>.
3 Immerse the measuring cell in the test sample.
4 Open the input window for the measurement of the tempera-
ture dependency with Calibration / TC calibration / TC nLin3.
