5.4 Measured value recording  

For the ion measurement of the media to be examined, they 
must first be mixed with the strengthening solution (stock so-
lution, factor 1:50). 
The  ion  electrode  is  completely  immersed  in  the  medium  to 
be measured at the measuring head. If a number of different 
test solutions are to be measured, it is advisable to rinse the 
ion  electrode  with  deionized  water  between  two  measure-
ments  and  carefully  shake  off  the  water  to  avoid  cross-
contamination of the samples.  
 
 

5.5 Maintenance and cleaning of the electrode 

After  use,  clean  the  electrode  with  deionized  water  and  dry 
carefully. Fit the protective cover, but make sure that the low-
er  end  of  the  electrode  does  not  rest  on  the  bottom  of  the 
protective cover. 
 

5.6 Replacing the battery 
 
Remove the battery 

 

Open  the  sensor  by  turning  the  screw 
cap  on  the  back  of  the  sensor  counter-
clockwise, e.g. with a coin. 
 
 
 
 
 

  

 

 Fig. 5 

 
Lever  the  battery  sensitively, 
e.g.  with  the  help  of  a  small 
screwdriver  or  a  small  pair  of 
scissors,  out  of  its  socket.  In-
sert  the  screwdriver  as  shown 
in Fig. 6.

Insert new battery 

 
Slide the battery under the golden metal nose (Fig.7-1). Make 
sure that the battery is completely under the metal nose and 
completely pushed to the upper edge. 

Push  the  battery  into  the  socket 
by  pressing  lightly  on  the  oppo-
site side.  
The  battery  slips  under  the  two 
plastic  lugs  (Fig.  7-2),  which  is 
also noticed by a short "click".

Before  closing,  make  sure  that 
the seal in the lid is not bent and 
lies neatly on the edge of the lid. 
Then  tighten  the  cover  clock-
wise.
