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/ Transmitter
should change in pitch. The lower the pitch, 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.
For SGV4 and MXT4 only, there will be a visual representation
of the quality of the connection in addition to the audible pitch
change. The greater the response on the display, the better
the signal will be on the pipe.
7. Adjust the Output Power Level to suit.
Using the Signal Generator/Transmitter:
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/ Transmitter pitch does not change then there is no signal being transferred onto the service.
