OPERATION
Locating Wire Path
With the probe pointed toward the ground, walk completely around
the transmitter location. An absence of tone or null will be detected
directly over the path of the wire. Movement to either side will
cause the volume of tone signal intensity to increase. Follow the
null to determine the wire path. (Refer to Figure 2).
Finding Wire Breaks and Nicks
When attempting to find breaks and nicks, you should decrease
the sensitivity of the receiver when pointing it off to either side of
the null. You will be able to notice the charge in signal intensity
immediately. Do not allow the meter to peg or go above 10. This
will greatly help in the fault locating process.
NOTE: The wire must have a path to ground to be successfully
located. These paths exists in a great majority of all direct buried
wires due to insulation imperfections, nicks, and bad splices. If
not, create one by grounding the remote end.
SETUP
NOTE: The transmitter produces high voltage. Turn the transmitter
off before handling the output leads. Disconnect all wires when
fault locating. Turn the selector knob to the BATTERY TEST
position. The meter should read between 8 and 10.
IMPORTANT: To ensure that the transmitter is producing optimum
signal, connect the red and black leads together and turn the unit
on. Turn the selector knob to position #5. The meter needle should
rise to at least a 10 reading.
1. With the transmitter off, connect the red lead to the wire to be located
and the black lead to a good earth ground with the stake provided.
(Refer to Figure 1)
2. Turn the transmitter on and start rotating the selector knob clockwise.
Once you leave the BATTERY TEST position and go to #1, the meter
needle will fall off to near zero. As you increase the output, the needle
will rise slightly with each advancement. Stop when the meter reads
between 4 and 8. The transmitter is now set for maximum efficiency for
this job. If a reading of 4 is not obtainable, reposition the ground stake.
3. Plug the optional handset into the receiver if desired, turn the receiver on
and point the antenna or probe end at the transmitter. A pulsing tone
should be heard and an indication should register on the receiver meter.
NOTE: High pitched tones from the headset may occur if the headset
cord gets to close to the receiver antenna or the receiver battery is low.
CAUTION Electric shock hazard:
Do not connect transmitter to any active AC circuits.
Failure to observe precaution may result in injury
and can damage the instrument.

• The end of a cut or broken wire can be located by following
the path until the null disappears and gives way to a hot spot.
Beyond the hot spot, no null can be detected. Back up until the
null is detected, and this will be the approximate end of the
broken wire. (Refer to Figure 3)
• Larger nicks in the wire can be located in the same way as
locating cut wires. Follow the null and strong signal along the
sides of the wire until the signal becomes very weak along the
sides of the null. This will occur within a relatively short distance.
The transmitted signal bleeds to ground at the nick and then
wants to return to the ground stake along the outside of the wire
itself. The majority of the signals will stop at the nick indicated by
the low receiver reading just beyond the nick. (Refer to Figure 4)
• To more accurately define the location of an open or larger nick
(ground fault), position the receiver tip on the ground near the
point where the last strong signal was detected along the side of
the path. The receiver tip should be pointing at the ground and
be approximately 6 inches to either side from the null. Because
you are so much closer to the path, the sensitivity knob must be
adjusted down until the meter reads just below 10.
While maintaining the 6-inch distance from the null, move the
receiver down the line, paying close attention to the meter reading.
Once you pass the open or nick, the meter will fall off rapidly.
Determining Depth of Wire
To determine the depth of the wire, first mark the ground directly
over the path. Turn the receiver sideways to the path, and tip it 45
degrees. Move the receiver away from the path, maintaining the
45 degree tip until a null is detected. Mark this spot. The depth is
the distance between the two marks. (Refer to Figure 5)
Two-Step Solenoid Valve Locating Process
Solenoid valves can be located provided all the wires leading to
them are intact and the solenoid itself is still good.
Step 1
1. Set-up transmitter as in “Set-up Section”. The null will be present
until you pass over a solenoid valve, and then the signal will
become extremely strong. Mark this spot. Check around the
hot spot for a null leaving the area. If the null continues, follow
it and mark any additional hot spots. (Refer to Figure 6) If only
one hot spot or valve is located, it will be the valve in question.

Step 2
2. If more than one hot spot is found, mark them and return to the
transmitter and turn it off. Lift the black lead from the ground
stake and connect it to the common wire. Turn the transmitter
on, set the selector knob to the highest reading, and return to
the first hot spot with the receiver. Touch the tip of the receiver
antenna to the ground in the center of the first hot spot and
set the sensitivity knob to read near mid-scale. Now go to the
second spot and without touching the sensitivity knob, check the
strength of the signal at each hot spot and determine which, out
of all of them, is the strongest signal. This is the value for the
station wire you are connected to.

Paso 2
2. Si se localiza más de un punto caliente, márquelos y regrese
al transmisor y apáguelo. Levante el conductor de color negro
de la punta de tierra y conéctelo al cable común. Encienda el
transmisor, ponga la perilla selectora en la lectura más alta
y regrese al primer punto caliente con el receptor. Conecte
la punta de la antena del receptor a la tierra en el centro del
primer punto caliente y ajuste la perilla de sensibilidad para que
lea cerca de la escala media. Ahora pase al segundo punto y
sin tocar la perilla de sensibilidad, verifique la potencia de la
señal en cada punto caliente y determine cuál de todos ellos
constituye la señal más potente. Este es el valor para el cable de
estación al que está conectado.

KING 521MANUAL DE INSTRUCCIONES
• El extremo de un cable cortado o roto se puede localizar siguiendo la
ruta hasta que desaparezca la respuesta nula y dé lugar a un punto
caliente. Más allá del punto caliente, no se puede detectar ninguna
respuesta nula. Retroceda hasta que se detecte la respuesta nula y este
será el extremo aproximado del cable roto. (Consulte la Figura 3)
• Se pueden localizar melladuras más grandes en el cable de la misma
manera que se localizan los cables cortados. Siga la señal nula y
potente a lo largo de los costados del cable hasta que la señal se
vuelva muy débil a lo largo de la respuesta nula. Esto ocurrirá dentro
de una distancia relativamente breve. La señal transmitida se purga a
tierra en la melladura y luego querrá regresar a la punta de tierra a lo
largo del exterior del cable mismo. La mayor parte de las señales se
detendrán en la melladura indicada por la lectura baja del receptor
apenas más allá de la melladura. (Consulte la Figura 4)
• Para definir con mayor precisión la ubicación de una melladura abierta
o más grande (fallo a tierra), ubique la punta del receptor sobre el
suelo cerca del punto donde se detectó la última señal potente a lo
largo del costado de la ruta. La punta del receptor también debe
estar orientada al suelo y estar aproximadamente a 6 pulgadas hacia
ambos lados de la respuesta nula. Debido a que está mucho más
cerca de la ruta, la perilla de sensibilidad se debe ajustar abajo hasta
que la lectura del medidor sea justo menos de 10.
Mientras se mantiene la distancia de 6 pulgadas de la respuesta nula,
mueva el receptor a lo largo de la línea, prestando mucha atención a
la lectura del medidor. Después de pasar la apertura o la melladura, el
medidor bajará rápidamente.
Determinación de la profundidad del cable
Para determinar la profundidad del cable, marque primero el suelo
directamente por encima de la ruta. Gire el receptor lateralmente
hacia la ruta e inclínelo 45°. Mueva el receptor para alejarlo de la
ruta, manteniendo la punta de 45° hasta detectar una respuesta
nula. Marque este punto. La profundidad es la distancia entre las
dos marcas. (Consulte la Figura 5)
Proceso de localización de válvulas solenoide de dos tiempos
Las válvulas de solenoide se pueden localizar siempre que todos
los cables que llevan a ellas estén intactos y el solenoide mismo
aún esté en buenas condiciones.
Paso 1
1. Configure el transmisor como en la “Sección de configuración”.
La respuesta nula estará presente hasta que pase por encima de
una válvula de solenoide y luego la señal se volverá sumamente
potente. Marque este punto. Verifique alrededor del punto
caliente para detectar una respuesta nula que salga de la
zona. Si la respuesta nula continúa, sígala y marque los puntos
calientes adicionales. (Consulte la Figura 6) Si solo se localiza
un punto caliente o una válvula, será la válvula en cuestión.
