The Earth Tester is designed for testing the resistances of any system of conductors
which is a conductive loop.
In particular, it enables measurements of earth resistances if it is in series in a loop with
its continuity conductor and different earths (extended earth produced for example by
means of a guard wire linking electricity pylons together, for energy transportation or
telecommunications; earths connected to one ground only).
