2. CENTRE LOOP LAYOUT (TL-1K6, 40x 40m Transmitter Loop)
A. Lay out the TL-1k6 transmitter loop first:
−
to ensure current flow and measurements are all positive, we
lay everything in a clockwise order;
−
a compass, optical square or tapes can be used to help make
the loop square - it does not need to be a perfect square
to still perform acceptably;
−
leave the loose end of the loop near the TX unit and
walk around with cable drum;
−
use the black markers on the
loop as a guide for the
corner positions:
B. Lay out RC-5 receiver coil next:
−
this is easiest to locate centrally;
−
either use people on the corners of the transmitter loop to
align someone in the middle
OR (easier) walk from the middle
of one side, toward the middle of the other side, measuring
the distance as you walk.
−
the RC-5 coil is running
clockwise when the black
connector is on the top (right);
−
ensure that the RC lead-in
cable is not coiled and
crosses the transmitter
loop at 90° (or as close as possible).
C. Lay out RC-200 receiver loop:
−
use the RC-5 as a guide for centring
and aligning the RC-200;
−
the RC-200 loop also has
corner markers on the cable;
−
at the corner of the RC-200 there is a
connector box with a diagram on it to show
which is the correct direction for laying
it out (see image, right);
−
ensure that the RC-200 cable
is not coiled, runs parallel to
the RC-5 cable separated by
~2m, and crosses the transmitter
loop at 90° (or as close as possible).
