Locating Utilities**

Passive location Power 60Hz and Radio
(No compass indicator is available in Power 60Hz or Radio
Modes) All other Passive locate modes will show the Compass
line direction indicator. And left/right arrows as seen in the Classic
Locate Mode section of this document.
1. Select the passive frequency with the "f"-button. (If the desired
8
frequency is not preset, switch to the user menu by pressing
and holding the "i"-button and choose it in the sub-menu
"frequency." Press the "Enter" button to highlight it. Go back
with a short press on the "i" button.)
2. Hold the receiver vertically and adjust the sensitivity by
pressing the "+" / "-" buttons so that the bar graph shows a

Active locating

Direct connection**

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.
1. Switch on the transmitter and select the desired frequency
with the "f" button (If the frequency is not present, use the "i"
key to access "frequency selection" in the menu and mark the
desired frequency with the "f" key. Press the "i" key to return.
Always select the lowest possible frequency to minimize
coupling to other lines.
2. Set the output power accordingly. (less is more)
From this point on, follow points 1 through 6 of the Passive

location 60Hz / Radio / CTV section of this document.
Signal clamp** (Frequencies above 8kHz):
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.
Induction** (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.
