• Description

The photo shows 2 examples of a plug assembly to send the electric field into the Earth of a power point. - Please understand that we can't sell these, as they are not to Australian Standard, without certification of any kind.  They are not necessary in Europe, as the Earth contact is part of the power points.

To get an objective indication of the electric field, your instrument must be grounded to earth. 

DANGER >>>  Have this done by an electrician, if you are not totally sure about how to do it. 

You must only use the EARTH contact in the plug, otherwise you will electrocute yourself and destroy the instrument.
