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.
Select the passive frequency with the "f"-button. (If the desired
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.)
Hold the receiver vertically and adjust the sensitivity by
pressing the "+" / "-" buttons so that the bar graph shows a
signal.
Continue locating in a grid across the area. See illustration (a)
below.
Determine signal maximum by carefully moving the receiver
back and forth. Adjust the sensitivity again with the "+" "-"
buttons.
Continue to locate the position of the line.

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.
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.

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.

Advantages: Automatic gain adjustment; easy finding/routing of lines with
the 3D mode.
Advantages: Automatic gain adjustment; line depth is permanently
measured, even when running offset to the line.

Classic locate modes (refer to the vLoc3 Series manual)
Available modes: peak, peak with arrows, null, broad peak, delta
null, omni direction.
The individual modes within the classic view can be changed by a
short press (<1 sec.) on the "Enter" button. If a mode is not visible
or not desired, it can be switched on or off in the user menu (long
press on the "i" key / classic display/selection with "Enter" key).
Locate Screens**
For all subsequent locating views, except Transverse Graph
and Sonde Mode:
The distortion level is displayed on the bar graph.
Green = low interference, Blue = some interference, and Red = high
interference level, treat the locating results with caution.
NOTE:
Locating views (classic, vector, plan view,
transverse graph, and sonde can be changed by a
long press on the "Enter" key (approx. 2 seconds).

The target line is below the receiver
when both signal peaks are on the
center line and the signal is not distorted.
The centerline does not indicate the
target line but serves as an orientation
for the two signal peaks and the cable's alignment!

Transverse Plot Screen (Refer to the vLoc3 Series manual)
Analyze the field shape at a particular location.
Signal overload - When the receiver is too close to the
inductive operated transmitter or a power transformer.
Shallow cable - When the cable is possibly less than 6-inches
deep. Proceed with caution!
Swing alert - When excessively swinging the receiver. Doing
so could result in misleading information.
Overhead cable - When the signal is mainly radiating from
above distorting the below-ground signal.
Warnings - Are audible sound with a vibration of the handle. Warnings
can be activated or deactivated in the user menu.
