Always connect just one sensor at a time! 

 
 

 
 
 
 
 
 

 
 
 
 
 
 

  

Always make sure that the connector sockets not in use are firmly capped, the sensor plug is 

        screwed on tightly and the USB connection cover is tightly sealed, otherwise the IP65 protection 
        cannot be guaranteed
