2.2 Connection Methods

1. Ensure the transmitter is connected in a
closed circuit before performing any
function.
2. The cable locator can only detect lines
that are connected in this manner .

Optional connections:
1. One-pole connection: Connecting the
transmitter using one lead. Because of the
high-frequency signal generated by the
transmitter, only one conductor can be
located and traced. The second lead serves
as ground.
2. Double pole connection: Connecting the
transmitter using both leads (for both live
and inactive circuits.
Live circuits:
Connect the "+" lead of the transmitter to the
live line and the "-" lead to the neutral line. If
there is no load placed on the circuit, the
modulated signal from the transmitter will
simply go through the mains and return back to
the neutral side of the transmitter.
Dead circuits:
Connect the "+" lead of the transmitter to one
end of the of the circuit and the "-" lead to the
other end. Alternatively, connect the "+" lead to
end of the line and the "-" end to a grounded
terminal.
