IMPORTANT SAFETY INFORMATION

DANGER
Immediate hazards which, if not avoided, WILL result in severe injury or death.
WARNING
Hazards which, if not avoided, COULD result in severe injury or death.
CAUTION
Hazards or unsafe practices which, if not avoided, MAY result in injury or property damage.

WARNING
Read and understand this material before operating or servicing this equipment.
Failure to understand how to safely operate this tool could result in an accident causing serious injury or death.

WARNING
ELECTRIC SHOCK HAZARD

• Contact with a live circuit could result in serious injury or death.
• Never allow this unit to be exposed to rain or moisture.
• Any device operation other than intended and outlined in this manual can impair the protection provided by the unit.
• Use accessories appropriate for the application and refer to the category and voltage rating of the accessory.
• Examine test leads prior to use to ensure they are clean and dry and that the insulation is in good condition.
• Prior to removing the case or battery cover, power off the unit then remove the test leads from the circuit.

Failure to observe any and all of these warnings could result in severe injury or death.

CAUTION
ELECTRIC SHOCK HAZARD

• Transmitter should never be connected to any active AC circuits.
• This unit does not contain user-serviceable parts. Do not attempt to self-service or repair this unit. Refer to service/warranty instructions in this manual.
  Failure to observe any and all of these precautions may result in injury and/or damage to the unit.

SETUP

NOTE: The transmitter produces high voltage. Power off the transmitter prior to handling test leads. When locating faults, disconnect all wires. The selector knob should be turned to “Battery Test” position and the meter should read between 8 and 10.
Connect the red and black leads together and turn the unit on.
The selector knob should be turned to “Position #5” and the meter needle should rise to a reading of 10 or above. This ensures the transmitter is producing optimum signal.
Ensure proper setup of transmitter prior to beginning to use the unit.

CAUTION
ELECTRIC SHOCK HAZARD

Never connect transmitter to an AC circuit.
Failure to observe this precaution may result in injury and/or damage to the unit.

1. Turn the transmitter to off position. Use the stake provided to connect the black lead to a good earth ground. Connect the red lead to the wire you wish to locate. (Refer to Figure 1)
2. Switch the transmitter to on position. Rotate the selector knob clockwise. You will see the meter needle fall to near zero as you leave BATTERY TEST position and go to #1. As output is increased the needle will rise slightly. Continue rotating the selector knob until the meter readout is between 4 and 8, at which point the transmitter will be set for maximum efficiency for this job. If you are not able to reach a reading of 4, reposition the ground stake.
3. Turn the receiver on (also plug in the optional headset if desired). Point the antenna at the transmitter. An audible pulsing tone will be heard, and a visible indication will register on the receiver.
   NOTE: If a high-pitched tone is heard from the headset it is possible that the headset cord is too close to the receiver antenna or the receiver battery is low.

OPERATION

Locating Wire Path
Walk around the transmitter location while pointing the probe toward the ground. When you are directly above the wire path, the unit will go silent—no tone will be detected. As the receiver is moved to either side of the wire path the intensity of the tone signal will increase. To determine the wire path, follow the null. (Refer to Figure 2).

Finding Wire Breaks and Nicks
In order to use the King AL unit to locate a fault, lower the receiver sensitivity when pointing to either side of the null. The change in signal intensity will become apparent. Do not allow the meter to read above 10.

NOTE: Most direct bury wire will have a path to ground due to insulation imperfections, nicks and bad slices. If a path to ground does not exist, create one by grounding the remote end. In order to be located the wire must have a path to ground.

To find the end of a cut or broken wire, follow the path until
the null disappears. At that point you will hear a “hot spot” or audible and consistent tone. As you move past this point, no null will be detected. This is the approximate end of the broken wire.
(Refer to Figure 3)

To find wire nicks, continue along the path as previously described, tracking the null sound at the wire and the tone sounds along the sides. At some point the tone to either side of the null will weaken over the course of a short area. At this point, return to the point where the last strong signal was detected, and place the receiver tip on the ground approximately six (6) inches to one side of the null. Mark your null path if necessary. Adjust the sensitivity knob down until the meter reads just below 10 and move the receiver down the line, maintaining the 6-inch distance from null. Pay close attention to the meter reading as you move along the path—once you pass the wire nick the meter will fall off rapidly. (Refer to Figure 4)

Determining the Wire Depth
To determine wire depth, follow the instructions above to locate the wire path. Mark the ground directly above the path. Turn the receiver sideways to the path, and tip it 45 degrees. Maintaining the 45° angle, move the receiver away from the wire path until you detect NULL. Mark this spot and measure the distance between this spot and the wire path. This is the depth of the wire (Refer to Figure 5)

Two-Step Solenoid Valve Locating Process
If all wires leading to a solenoid are intact and the solenoid is good, then a solenoid valve may be located using the King AL device.

Follow the instructions shown above to set up the transmitter. Follow the wire path, detecting NULL and tone sounds, until the signal becomes extremely strong. When the strong signal is detected, mark this “hot spot” and move around that area, listening for a NULL moving away from that area. Follow this NULL tone, marking any additional hot spots. (Refer to Figure 6).
If only one hot spot is located, this is the valve in question.

In the case that more than one hot spot is found,
follow the steps below.
Mark each hot spot. Turn off the transmitter, move the black lead from the ground stake and connect it to the common wire. Turn the transmitter back on and set to the highest reading. Return to the first hot spot, touch the receiver tip to the ground, and turn the sensitivity knob to mid-scale. Move through each hot spot, watching the strength of the signal at each. Determine which hot spot has the strongest signal. This is the station wire you are connected to.
