Using the Generator/ Transmitter: Direct Connection
5. Connect the black Earth Lead to the Earth Stake (or the
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 Generator/ Transmitter should change in pitch.
The lower the pitch, then the better the signal will be on the
metal pipe.
If there is no change of tone it may be that some dirt, rust
or paint on the pipe is preventing the Direct Connection Lead
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.
(SGV2 Generator and MXT2 Transmitter only:
There will also be a visual representation of the quality of the
connection in addition to the audible pitch change. The greater
the response on the display then the better the signal will be
on the pipe).
7. Adjust the Output Power Level to suit.
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 Generator/ Transmitter pitch does not change then there is no signal being transferred onto the service.
