Maintenance 

7.3.1. 

Replacing the zero filter 

 

(1) 

Open the cover at the bottom of the 
main unit. 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

(2) 

Remove the zero filter. 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

(3) 

Insert a new zero filter. 

(The zero filter needs to be firmly 
inserted as an imperfect insertion could 
result in a leak, thus leading to incorrect 
measurement values being obtained.) 

 

 

<Example of imperfect insertion>
