Product Manual

Contact Rod for Soil and Brass Valves
The contact rod is provided to assist in contacting the sensor to materials that
are soft, spongy, porous, or non-ferrous. To use, remove the nut on the base of
the ground microphone with the nutdriver and attach the contact rod to the brass
thread. If only a short rod is needed, attach only the pointed section of the con-
tact rod to the bottom of the sensor. For deep brass valves at curb stops, use all
three (3) sections of the contact rod, and push the point of the contact rod firmly
against the brass valve. For water leak searches in areas covered by loose soil or
grass cover over the water line, use only the pointed bottom section of the contact
rod.
In either application, do not try to hold the sensor or the contact rod with your
hand, since this will cause small movements and "crackling" sounds at the point
of contact of the rod. Let the sensor or the contact rod rest against the curb box
wall or the meter box wall. For water leak searches in areas covered by loose soil
or grass, push the pointed contact rod firmly into the dirt two to six inches, but do
not hammer it into the ground or try to force it in deeply. It only needs to make
firm contact in the ground.
WARNING!
The sensor and the contact rod are not a digging tool, boring bar, or other heavy
tool. Use these other tools for pushing through the soil or digging holes, and do
not risk damaging the ceramic element inside the sensor by using the contact rod
in this manner.
