POWER
The transmitter is powered by AC adapter or internal batteries. To use
the AC adapter, insert the round plug of the adapter into the “12V”
external power receptacle on the transmitter panel and plug into a
wall outlet.
The transmitter uses 8 “D” (LR20) alkaline or rechargeable batteries
that are installed inside the transmitter battery compartment. Remove
the battery compartment cover to install the batteries.
The receiver is powered by a 9 Volt square (6LR61) alkaline battery.
To install this battery, remove the battery compartment cover located
on the back top portion of the receiver. Install the 9 Volt battery by
connecting it to the battery snap boot inside the battery compartment.
Replace the battery cover.

TRACING WIRE
After the transmitter has been properly connected with a good
ground, turn on the receiver. The receiver defaults to the most recently
used mode with null antenna reception at every start-up. Place the
receiver near the operating transmitter. A beeping sound should be
heard indicating that the receiver is working properly. A steady high
pitched tone could indicate that you are too close to the receiver or
your batteries are low. A fading or scratchy signal may indicate low
battery.
There are two antenna methods for tracing a path; Null or Peak.
The receiver defaults to Null every time it is turned on. Null means
an absence of signal when pointed directly at the cable in question
and louder to the left and/or right of it a few inches. Peak means the
opposite, that the signal is loudest over the cable. You may select
which mode works best. In general, the closer you are to the cable,
the louder the signal should be except for directly over the cable in
the Null mode. The modes can also be flipped while tracing to give a
better indication of path trace quality.

KING INNOVATION
I
11
KING DL
In Direct Clip-on mode, begin the wire trace by sweeping the area
approximately 5-10 feet from the transmitter. Begin by searching for
the null response. Until the null is acquired, you may receive audible
responses of varying degrees. Follow the signal response until the
signal is lost while marking the path as you trace.
In the Broadcast mode, the signal saturates a circle for at least 20
feet around the transmitter, so you must begin by walking out of that
area, then circling to find the traced wire or pipe.
NOTE - THE RECEIVER AND TRANSMITTER MUST ALWAYS BE
IN THE SAME MODE TO OPERATE CORRECTLY.
The selector arrows on the receiver control panel regulate the
volume level of the receiver, both headphones and external speaker.
Additionally the signal bar on the receiver display will indicate the
signal level visually. After connecting and turning on the transmitter
and the receiver, point the receiver toward the ground in the direction
of the cable and listen for the beeping signal.
FINDING FAULTS
Breaks or severe wire damage can be found with the KING DL. The
setup of the unit when finding faults is the same as it would be when
tracing wire. However, whereas the traced wire continues to emit a
signal along the path of the cable, a break will cause the signal to
stop at the point of the break. A nick or damage will cause the signal
drop to a lower level but not necessarily end. Either the speaker or
the analog meter on the receiver will indicate this drop.
Be sure the cable or wire you are tracking is grounded - this
completes the “loop” for tracing the current signal. To trace a cable,
it must be grounded, either mechanically using a direct physical
ground at one end or capacitively using the ground stake. Capacitive
grounding generally applies to cable buried directly in the earth.
The signal needs a path to return to the ground stake and without
it, you will not get a good locate. A bad ground is indicated on the
transmitter output signal meter when an OK or mid-range signal level
doesn’t appear even at full power. In many cases, a direct buried
cable fault will provide this grounding and allow for
a cable to be located.

12
I
KING INNOVATION
INSTRUCTION MANUAL
A general rule is the greater the damage to a cable, the greater the
drop off signal at the point of damage. Conversely minimal damage
or weak grounding will show little change. Small faults are sometimes
difficult to locate.
FINDING IRRIGATION SOLENOIDS AND VALVES
Connect the red lead of the transmitter to the station wire leading to
that valve and the black to ground stake. Operate the KING DL as
above and begin your locate. When you reach the point where a
valve/solenoid is located, the signal will expand into a large (approx.
2-4ft) diameter area of signal. Many times this signal volume will get
louder. This is your indication that you are over a valve or solenoid.
An alternate method starts by tracing and marking the wire path.
Once the wire path has been traced you must power the transmitter
off, remove the black lead from the earth ground and connect it to the
common wire. In the case of multiple common wires it is suggested
that you isolate and connect to the common wire that services the
target valve. Connecting to multiple commons will work, however it
weakens the signal response.
Power the transmitter on and adjust the output signal to suit your
needs. High power output is not necessary and will limit battery life. It
is advised that you once again point the receiver at the transmitter to
assure that both units are on and functioning properly.
Slowly follow the pre-marked wire path. There will be an absence of
signal response due to canceling of the closely parallel wires until you
near the valve. As you move closer to the valve the receiver will begin
making a chattering sound which will intensify.
Even with the volume at its lowest setting the response of the valve
solenoid will be very loud. Pinpointing the exact location of the
solenoid is possible by decreasing the volume. The lower the volume
is, the more accurate you can be.
Slowly start moving the receiver in an X pattern above the high
pitched area, continue reducing the volume while moving the tip
of the receiver closer to the ground. Between the proximity of the
receiver tip to the ground and the reduction in volume you can tell
exactly where the valve solenoid is. Use a pointed probe to find
the outline of the valve box before excavating. This will assure that
unwanted damage isn’t a result of your locate.

KING DL
There may be more than one valve on the cable being traced.
You may wish to continue past the first valve located to determine
if other valves are also located on this wire.
BROADCAST MODE
Broadcast mode is connectionless and different from using the direct
clip-on method of connection that has previously been discussed. It
is not as precise or strong as direct connecting, but when access to
cables is limited or just a quick scan is required, Broadcast Mode can
be very useful.
Broadcast mode is excellent for finding telephone or cable TV lines.
It is less useful with wires attached to solenoids. The principle in use
with Broadcast mode is AC induction. On ordinary wires, that works
well. It can work for sprinkler wire but the solenoid sometimes has to
be eliminated from the circuit. This can be done by disconnecting the
solenoid and grounding the wire manually. The problem is that the
solenoid acts as a signal dampener with AC inductance. By removing
the solenoid from the circuit, you can find sprinkler wires in broadcast
mode. Deactivated 2-Wire systems do not have this issue and are
traceable as they exist in the ground.
Broadcast mode uses an inductive antenna located in the transmitter
case to broadcast a signal around the case in an approximately 25
foot radius in all directions. It allows the user to transmit or induce
signal from the transmitter directly into the ground. Any grounded
metallic cable or pipe traveling through this electromagnetic field will
pick up at least some of the tracing signal, making that conductor
traceable with the receiver.
Place the transmitter on the ground over the cable you wish to
trace and select Broadcast. The transmitter is now inducing signal
approximately 20 to 25 feet from it, and energizing any conductors
in that field. You may now trace any conductor that has picked up
that signal.
Also note, when the user is within 20 to 25 feet of the transmitter,
you cannot trace a cable because the signal from the case itself will
overpower the induced cable signal. The user will always hear the
transmitter signal within 20 feet of the transmitter case.
The Broadcast mode does not have a power output adjustment on
the transmitter. In addition, remember that ALL conductors in the
ground that can pick up the signal will be detected.

KING INNOVATION
INSTRUCTION MANUAL
Therefore, tracking is better in non-congested areas.
It is important to understand the uses and limitations of Broadcast
Mode when compared to direct connection with the alligator clips.
INDUCTIVE CLAMP MODE
To use the inductive clamp, plug the clamp into the clamp receptacle
on the transmitter and place the transmitter in the “Broadcast or
Clamp” mode. Clamp around the cable or pipe to be traced. Please
note, the clamp must be placed between grounding points on each
end of the cable and the cable must be grounded on both ends for
the clamp to work. The clamp induces current onto the cable and the
current will not flow if the cable isn’t grounded on both ends.
You can increase the effectiveness of the clamp by wrapping the wire
around the clamp as many times as possible. Like a transformer, the
more wraps, the more power.
TRACING LIVE ELECTRICAL LINES USING PASSIVE MODE
The KING DL receiver has the capability of detecting live electrical
AC lines in the ground without connecting to them. This is known as
Passive AC mode. In passive mode, no transmitter is used.
To use the passive mode, turn on the KING DL Receiver and select the
Passive AC mode using the control panel. This switches the receiver
into an unfiltered mode that detects the electrical field generated

DO NOT ATTEMPT TO CONNECT THE ALLIGATOR LEADS
OR ANY OTHER COMPONENT TO LIVE ELECTRICAL LINES.
DEATH OR INJURY COULD OCCUR.

by 50Hz or 60Hz electrical current. Once the KING DL Receiver is
on, simply search an area until you hear a buzzing sound. There is
no beeping signal as the transmitter is not used. Follow the buzzing
sound in either null or peak mode, both will work, to track the cable.
DO NOT RELY ON THE 50/60 Hz PASSIVE MODE AS
THE SOLE METHOD OF LOCATING POWER LINES. Passive
mode will not detect power cabling if there is no live electrical current
present in the cable at the time.
HOW TO DETERMINE DEPTH
Find the null over the wire path and mark it. Then place the tip of the
receiver on the ground at the mark. Without lifting the receiver tip
from the ground, lower the top of the receiver to approximately a 45
degree angle and slowly walk the receiver away from the wire path
until you re-acquire the null. The distance between the wire path and
the newly established null is the approximate depth of the target. This
is the Equilateral Triangle method.
DETERMINING TARGET ACCURACY
Place the tip of the receiver on the ground directly over your
suspected target location, switch from null to peak by pressing
the mode selection pad. The peak and null responses will agree if
the locate is accurate. If the peak and null are off by more than a
few inches the location is not accurate. Toggling between the null
and peak modes often when locating the wire path will ensure an
accurate reading.
