Temperature Coefficient 

The unit uses the temperature coefficient to calculate 
temperature compensated conductivity. The default value is 
1.91%. To change the temperature coefficient, use the “UP” 
and “DOWN” keys to adjust the value between 0 and 4.00%. 
Press “ENTER” to save the new value and the unit will go into 
the next calibration parameter automatically. If “MODE” is 
pressed instead of “ENTER”, any changes made will be 
cancelled and the previous calibration settings will be 
retained. 

Temperature Reference 

The unit uses the temperature reference value to calculate 
temperature compensated conductivity. The default value is 

25

℃

. To change the temperature coefficient , use the “UP” 

and “DOWN” keys to adjust the value between 15

℃

 to 25

℃

. 

Press “ENTER” key to save the new value and the unit will go 
into the next calibration parameter automatically. If “MODE” 
key is pressed instead of the “ENTER” key, any changes 
made will be cancelled and the previous calibration settings 
will be retained.
