This is a low-cost
receiver that is tuned to 50-60Hz and picks up the
electromagnetic wave when current is present in the cable. It
will detect loaded lines where most others fail, because of
advanced receiver circuit and a precision wound antenna.
Not only are low
energy signals or waves detected, but also some low impedance
grounded faults, underground transformers, and splices can be
found. Operating the receiver/antenna "gun" and headphones is
very simple.
The AT-9 comes
complete with headphones and foam lined carrying case designed
for rugged protection of the instrument. An external
loudspeaker box is available.
The model AT-9
requires less than 1 amp load current to operate to a depth of
3 feet. |
