10.2.11Switching off the temperature compensation (TC off)
7 Slowly warm or cool the test sample (standard 1) until the end
temperature End temp. is achieved.
Each time the nominal temperature for a measuring point is
reached a dataset is stored.
At the end of the series of measurements for the solution (stan-
dard 1), the corresponding measuring record is displayed.
8 Confirm the record with [Continue].
9 Repeat the steps 5 to 8 for all further solutions (standard 2 to x).
The corresponding calibration record with the determined tem-
perature coefficients is displayed at the end of the calibration.
If the calibration is successful, the determined temperature
dependency for the TC nLin3 method is stored and used for fur-
ther measurements with this method.
10 Confirm the record with [Continue].
[nLin4] is displayed in the status line of the measuring channel.
1 Highlight the channel of the conductivity measuring cell in the
measured value display.
2 If necessary, select the measured parameter with <MODE>.
3 Switch off the usage of a temperature compensation with Mea-
suring / Temperature coefficient / TC off.
The temperature compensation is no longer displayed in the
status line.
