8.5 Calibrating the temperature coefficient using

manual temperature entry

Note

During calibration, the reference temperature and the working 
temperature can be approached in any sequence.

Immerse the conductivity cell and the temperature sensor in the 
medium to be measured.

WORK.T shows you that the working temperature that will be used 
later on has to be entered.

Note

The reference and working temperatures must differ by at least 5°C.

Enter the working temperature (e.g. 40.0 for 40.0°C), continue 
with .

Temper the medium to be measured to the reference 
temperature.

- The uncompensated conductivity is shown in the bottom line in 

the LC display.

The current value can be accepted immediately by pressing 

 

(for less than 1 second).
