INTRODUCTION

The CL 2150 Locator is specially designed to detect camera systems

and sondes and the unit is capable of detecting buried power cables,

CATV cables, gas and water pipes, sewer lines, telephone cables, fi-

ber optic cables with sheath.

The Transmitter/Sonde emits a signal. The Receiver detects the sig-

nal. You can locate the relative position of the buried pipe of camera

by following the tracing signal.

For sonde locating & camera head locating a signal is generated by

the sonde or camera head and the receiver detects the signal giving

the user proximity cues to determine its location.

Unpack your new CL 2150 Camera and Sonde Locator. Make sure

there is no shipping damage and all the parts are included.

Locate the battery compartment on the back of the “head” of the Re-

ceiver. Open the compartment using a Phillips screwdriver. Install

the six Duracell® “C” batteries as marked. NOTE: For longer bat-

tery life and reliable operation under adverse conditions, use only Du-

racell® alkaline batteries

DISCLAIMER OF LIABILITY

HATHORN CORPORATION SHALL NOT BE LIABLE TO DIS-

TRIBUTOR, RESELLER, OR ANY OTHER PERSON FOR AN IN-

CIDENTAL, INDIRECT, SPECIAL, EXEMPLARY OR CONSE-

QUENTIAL DAMAGES, OR INJURY OF ANY TYPE WHATSO-

EVER, AND CAUSED DIRECTLY BY PRODUCTS SOLD OR

SUPPLIED BY HATHORN CORPORATION.

ABSOLUTE SIGNAL STRENGTH

The CL 2150 Locator receiver provides the operator with a direct

measurement of the receiver’s signal strength. The measurement is

displayed with three numerical digits (ex: 485) located at the bottom

of the LCD display. The measurement range is from -100 to 999 indi-

cating a very week signal (-050) to a very strong signal (999) Abso-

lute Signal Strength is independent of the GAIN setting or meter

reading. It gives the operator information about the actual amount of

signal being radiated from the conductor and received by the receiver.

Measuring Absolute Signal Strength at any time is done by reading

the number at the top of the LCD display. The Absolute Signal

Strength is displayed even when the meter reading is off scale (too

high or too low).

GAIN CHANGE INDICATION

The GAIN up and down buttons are used to increase and decrease the

gain in small amounts. If the meter reading is very low, pressing the

GAIN UP button will center the meter reading to mid-scale. Like-

wise, if the meter reading is very high, pressing the GAIN DOWN

button will center the meter reading to mid-scale.

DIGITAL DEPTH ESTIMATE

The CL 2150 Locator estimates the depth automatically. The depth is

displayed at the top of the LCD display in feet or inches. Digital

depth is useful in quickly determining the depth of the conductor dur-

ing path locating.

To change the Depth Measurement from SONDE to LINE, hold the

Frequency Key for three seconds and the next setting will appear.

Caution must be exercised when using the digital depth feature, as

tilted magnetic fields and adjacent conductors can significantly influ-

ence this measurement. The operator should periodically check for

adjacent conductors and tilted magnetic fields when taking push but-

ton depth readings.

LOW BATTERY

The CL 2150 Locator will indicate low battery condition by display-

ing the low battery icon at the bottom right of the LCD screen.

FREQUENCY &

MODE BUTTON

The configuration of the

unit (See page 3), will

determine the functional-

ity of the Frequency & Mode button. If configured to 512, the unit

will only operate in 512Hz Sonde locating mode and the Frequency

Button will be functionless.

If configured to U3, the unit will only offer multiple sonde locating

frequencies. Press the frequency button to toggle through available

frequencies. Press and hold the frequency button for 3 seconds to tog-

gle between line mode and sonde locating modes.

SONDE MODE: 512HZ, 640HZ, 8KHZ, 33KHZ.

The unit may be configured to the following line mode frequencies:

passive 50hz & 60hz, passive rF, 512hz, 640hz, 8khz, 9khz, 33khz,

65khz, 82khz, 200khz, 478khz

GAIN BUTTON (UP OR DOWN)

Used to adjust the gain level for the receiver. When the gain button is

pressed, The receiver will adjust the gain up or down. If the bar graph

is off scale, pressing the GAIN up or down key will automatically

adjust to 85% on the scale display.

NOTE:

WHILE HOLDING “POWER” BUTTON, PRESS THE

“DEPTH” BUTTON TO NAVIGATE THROUGH FRE-

QUENCY OPTIONS. CHOOSE “512 Hz” FOR

HATHORN SYSTEMS.

LOCATING A SONDE OR CAMERA HEAD USING THE CL

2150

Before you begin, you must

choose a Sonde that will

match the same frequency as

the receiver. You will need a

Sonde with a frequency of

512HZ, 640HZ, 8KHZ, or

33KHZto use with the CL

2150 Locator Receiver.

The key to Sonde locating

success is practice and patience. Before going out on your first locate, it

is a good idea to take your receiver and Sonde out and try locating the

Sonde and calculating the depth.

Attaching a Push Device

Attaching a push rod to the

Sonde can be accomplished

by using the coupling on the

end of the Sonde. A spring

coupling is recommended to

allow the sonde to move eas-

ier. Or, if you need to attach

the Sonde to a sewer auger, it

is recommended you use

duct tape and apply as the

shown in the figure below. If

taping the Sonde on a metal

pushing device, it is recom-

mended to place the battery

side of the Sonde closest to

the device. This will allow

for the best performance.

Wrap the snake for approxi-

mately 1 foot in the location

where the Sonde is going to

be attached. Also attaching the Sonde 18 inches behind the cutting head

is recommended. First, wrap the Sonde in the duct tape and then attach

the Sonde to the snake using the duct tape.

LOCATING A SONDE

Hold the Receiver antenna direct-

ly above and in line with the

Sonde, as shown below. The Re-

ceiver sensitivity needs to be ad-

justed for a meter reading indica-

tion between 60% to 80%.

The radiation pattern of the Sonde

is shown below. The PEAK sig-

nal is when the Receiver is held

directly over the Sonde with the

antenna in line with the Sonde.

Both Ghost signals can be located

behind and in front of the Sonde. By locating the ghost signals, the

user is confirming the accuracy of the locate.

Start by following the suspected path of the pipe and use the CL

2150 Locator to locate the SONDE. Stop locating when the PEAK

reading is found. Then rotate the RECEIVER as shown in the fig-

ure below. When pivoting the RECEIVER, do not change the verti-

cal position. The RECEIVER will indicate a PEAK when the RE-

CEIVER antenna is in line with the SONDE.

Now move the RECEIVER side to side (across the path of the pipe)

as shown below. When the PEAK is found, the RECEIVER is di-

rectly over the SONDE. Mark this location. Next, check for ghost

signals in front and in back of the SONDE to confirm the location.

DEPTH MEASUREMENT OF CAMERA HEAD OR SONDE

Once the SONDE has been located, the depth can then be found. Refer to

the figure below for a reference. Start by moving the RECEIVER along

the path behind the SONDE with the antenna in line with the SONDE and

find a NULL between the PEAK ghost signals. Mark this point (A). Then

move the RECEIVER along the path in

front of the SONDE and find another

NULL. Mark this point (B). Next,

measure the distance between these two

points. The depth of the pipe is 0.7

times the distance between the two

points.

PUSH BUTTON DEPTH

The CL 2150 Locator is specially de-

signed to measure the SONDE depth

digitally.

To use this feature, the RECEIVER must be placed in the position shown

in the diagram above. The RECEIVER antenna must be in line with the

SONDE.

The RECEIVER must also be in the SONDE mode (holding the Depth for

a long press of three seconds switches depth mode). Locate the SONDE

as described previously.

When the SONDE has been located, press the DEPTH button. The LCD

display will indicate dEP, SON and display the depth of the SONDE in

feet or meters.

The only way to be sure of the depth of a utility is to expose the utili-

ty. At any time, the depth readout may be inaccurate as it may be af-

fected by metallic objects in the ground.

Caution must be exercised when using the push button depth feature, as

tilted magnetic fields and adjacent conductors can significantly influence

this measurement. The operator should periodically check for adjacent

conductors and tilted magnetic fields when taking push button depth read-

ings.

LOCATING A CABLE OR PIPE PATH

Using either a Line Transmitter or Passive locate mode a user

may be able to locate a buried utility. Hold the RECEIVER so

that you can see the LCD bar graph and controls easily. Make

sure the RECEIVER and the TRANSMITTER FREQUENCY are

both set the same, 512Hz.

PEAK MODE LOCATING

Keep the RECEIVER in a vertical position. Move the RECEIVER

left to right across the path. When the RECEIVER is directly

above the cable or pipe, rotate the RECEIVER for a maximum sig-

nal. As you move the RECEIVER away from the cable path, the

meter reading (and audio frequency response) will drop off.

If you rotate the RECEIVER while over the cable, a sharp NULL

will identify the cables’ direction. It is aligned with the flat side

of the RECEIVER.
