10.2.9 Selecting and determining the nonlinear temperature
compensation TC nLin3
Note
The measuring method can only be started if Ref. temp., Start temp.
and Temp. interval are selected so that the reference temperature cor-
responds to the nominal temperature of a measuring point: Ref. temp.
= Start temp. + x*Temp. interval
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.
5 Enter the start temperature (Start temp.), end temperature
(End temp.) and temperature interval (Temp. interval).
Enter the number of standards and the corresponding concen-
trations.
The concentration unit entered here is displayed as the unit of
the measured value display after the calibration is completed.
6 Confirm with [Continue].
The display shows:
z the current conductivity value
z the current temperature
z information on the nominal temperature of the next measur-
ing point and the temperature difference between the cur-
rent temperature and the nominal temperature
