SETUP AND SIGNAL COUPLING
4.3.2 Coupling using special connection accessories
• Coupling via adaptor cable
(The house connection set described
in this section is an optional accessory
- see "Spare parts and optional
accessories" on page 28)
The signal from the transmitter can be
directly coupled to plug sockets, cable
TV connections and telephone jacks
with the aid of a suitable adaptor
cable. In doing so, it is not necessary
to disconnect the lines.
Elcometer offers a ready made house
connection set for this type of
coupling.
• Coupling via transmitter clamp
(The transmitter clamp described in
this section is an optional accessory -
see
"Spare
parts
and
optional
accessories" on page 28).
The transmitter signal can be coupled
to cables which are easily accessible
with the aid of a transmitter clamp. It is
not necessary to disconnect the
cables.
By ensuring that the transmitter clamp
is completely closed around the cable,
only a small leakage field will be
generated.
This
can
significantly
reduce the unwanted coupling of the
signal to neighbouring lines.
Ideally the cables must be grounded
at both ends; but even if they are not
grounded at one end, selecting high
power transmitter output will assist
easy location.
