Grounding 

 

Good grounding is highly demanded so as to avoid signal interference. Please see below pictures, all you need to do is 
to ground the displayer. And the sensor grounding is unnecessary. Grounding place is like stairs and railing. 

 

To define whether vortex is well grounded initially, user need to check whether frequency is 50HZ or 60HZ or not. If it’s 
always 50HZ or 60HZ, it means grounding is poor. Please see details in 

9.2

 to check frequency value.
