5. Connect the black Earth Lead to the Earth Stake
(or an alternative earth point). If your earth point
is too far away from the pipe access point for
the black Earth Lead to reach then use the
yellow 10 metre Auxiliary Earth Lead instead.
6. As the Earth Lead is connected to the Earth
Stake the audible signal from the Signal Generator
should change in pitch. The lower the pitch,
then the better the signal will be on the metal pipe.
If there is no change in pitch it may be that
some dirt, rust or paint on the pipe is preventing
the Crocodile Clip or Magnet from making a good
contact with the pipe. Alternatively it may be that
your earth point is at fault. Change the position
of the Earth Stake or use an alternative earth point.
Using the Signal Generator: Direct Connection
NOTE If it is not possible to use the Earth Stake use a nearby metal fence post, manhole cover or gully cover.
NOTE If the Earth Stake cannot be inserted into the ground then simply laying it flat on the ground can sometimes
provide a successful earth connection (especially if the ground is wet).
DO NOT use something that may have another metallic service attached to it, such as a metal street lighting column.
NOTE If the Signal Generator pitch does not change then there is no signal being transferred onto the service.
