         is  then  "locked"  and  will  not  respond  to  further  changes 
from the   
         pH  electrode.  The  "locked"  display  is  the  pH  value  of  the 
sample at   
         the set sample temperature. 

       
              If "

OvEr/Undr

" is displayed, the pH value measured is  out 

of the 
              “16.00/-2.00 pH” range. 
 
  3.5  For samples that are inherently unstable, the instrument  

will not autolock. Use the pH NON-AUTOLOCK mode for 
measurements. 

 

4.Measurement with manual temperature compensation in the pH   

    NON-  AUTOLOCK mode.

 

 
  4.1  Connect the pH electrode to the top of the instrument.  
  4.2   Press the [MODE] key for the LCD to display pH and for 
the 

 AUTO annunciator to be off. 

  4.3   Rinse the pH electrode with distilled water and immerse it 
in the 

sample to be measured. 

  4.4  Set the instrument to the temperature of the sample as 2.2 of  
pH 

CALIBRATION section. 

4.5  Allow sufficient time for the display to stabilize. The 

instrument    
Will display the pH value of the sample at the set sample 
temperature. 

 
         If "
