Maintenance 

The instrument is maintenance-free. 

We  recommend  the  following  regular  inspection  to 
guarantee reliable operation and a long service life: 

• 

Check the reading. 

• 

Check the function in combination with down-
stream components. 

• 

Check the leak-tightness of the pressure con-
nection lines. 

• 

Check the electrical connections. 

The exact test cycles shall be adapted to the oper-
ating  and  ambient  conditions.  If  various  instrument 
components  interact,  the  operating  instructions  of 
all the other instruments also need to be observed. 

Transport 

The instrument must not be exposed to mechanical 
shocks.  It  may  only  be  transported  in  packaging 
specifically intended for transport. 

Service 

All  damaged  or  faulty  instruments must  be  sent  di-
rectly  to  our  repair  department.  Please  coordinate 
all shipments with our sales department.  

Process  media  residues  in  and  on 
dismantled  devices  can  be  a  hazard 
to  people,  animals  and  the  environ-
ment.  Take  adequate  preventive 
measures.  If  required  the  instruments 

must be cleaned thoroughly. 

Accessories 

• 

Connection cable with M12 connector 

• 

Assembly set for wall mounting 

• 

Adapter for parameterisation via PC software 

10  Disposal 

For the sake of the environment ....  

 Please  help  to  protect  our  environ-
