10.3. Conductivity measurement with manual temperature
compensation
The measurement with manual temperature compensation may be made in
stable work conditions, e.g. during measurements in laboratory, especially
with use of thermostat, or in case of the temperature probe damage.
Disconnecting the temperature probe switches the meter to manual
temperature compensation.
In case of measurement with manual temperature compensation:
-
connect the conductivity cell to the F1 connector (pic.2);
-
disconnect the temperature probe;
-
turn the meter on with the button;
-
choose the conductivity measurement unit according to the subchapter 6.1;
-
if the conductivity cell has not been calibrated earlier, calibrate it according
to the chapter 9;
-
measure the temperature of the solution with thermometer;
-
enter the measured temperature value for manual compensation according
to the point 6.2.1 ;
-
place the cell in the measured solution, it canot touch the walls and the
bottom. The measuring cell should be filled with the sample solution and
shouldn’t include any air bubbles, the electrode’s surface should be evenly
moistened*;
-
after stabilisation read the result (pic.13).
Pic. 13
* - air bubbles may be removed by moving the immersed cell. In order to make moistening of the electrodes
easier, it is recommended to immerse the cell in distilled water with washing-up liquid, and than wash it in
distilled water.
