Direct Connection Using the Genny

Chapter 23 of 33 · printed page 13

Ensure there is a noticeable drop in Genny tone when a direct connection is made to a metallic structure (except when the capacitance method is used). If no drop in tone is heard, ensure the connection or earth is good.

A suitable earth is: the supplied Genny earth pin in the ground, a buried metal structure (i.e. a manhole lid), or use of water on the earth pin or placing it in a puddle.
