Connect the transmitter with the supplied connection leads. Connect
the red wire to the target conductor and the black wire to ground. The
ground stake should be at a 90o angle to the target line if possible. To
help reduce signal interference, there should be no other lines (if
possible) between the ground spike and the target line.
Active locating
Direct connection**
Connect the signal clamp to the transmitter and place it around the
corresponding target line.
Then follow points 1 - 3 from the Direct connection section of this
document.
Signal clamp** (Frequencies above 8kHz):
Place the transmitter (without connection leads or clamp attached)
on the ground with the handle in the cable's direction. Do not place
the transmitter on manhole covers or other metallic objects as the
signal will not be able to penetrate them. When locating, maintain
a distance of at least 50ft from the transmitter. Otherwise, the
airborne signal from the transmitter will be located and not the
target line. Now follow points 1 through 3 in the Direct Connection
section of this document.
