Load Coils
This function counts up to five load coils on the pair and
determines the distance to the first one. The distance
measurement requires that you specify the wire gauge
of the pair. This is done in the Load Setup screen. Use
the [Up] and [Down] arrow keys to highlight the correct
wire gauge. Use [Enter] to accept that choice.
The Load Coils screen will appear and an hour glass
will be visible at the bottom of the screen during the
measurement. When complete, the load coil count will
be visible in the box on the right and the distance to the
first load coil will be visible in the box labeled “Nearest
Load”. If no load coils are present the count will be 0 and
“Not Found” will be visible in the “Nearest Load” box.
After the test is done, press the [Enter] key to repeat the
load coil count. Press the [Return] key to return to the
Toolbox menu or press the [Setup] key to change the
wire gauge.
It is not necessary to have any particular length of
cable before the first load coil, but you must have at
least 3000 feet (1000 meters) of cable after each load
coil for the Load Coil function to count properly.
You may also use the TDR function to find the distance
to the first load coil on the pair.
