!
!
!
!
!
!
Walk along the suspected path of the pipe. When you’re within proximity of the sonde,
your receiver will produce a tone that is known as a peak signal. When the receiver
passes over the equator of the Sonde the tone will suddenly become void which is
called a null.
You’re looking for a peak -null- peak signal when you are passing the Equator of the sonde during step 1.
3.
Place a marker on the surface where you just located your first null.
4.
Walk in a circular motion no more than 6ft towards the other side of the suspected path of the pipe. The receiver
will produce a peak -null- peak signal again when you pass over the other side of the sonde.
5.
Place a marker on the surface where you just located your second null and have completed step 1.
NOTES:
The receiver can be at any rotation along during Step 1.
The deeper or further away you are from the Sonde, the wider the peak -null- peak signal will be. Adjust signal strength
up or down with the gain control as needed to narrow your peak -null- peak signal . This step is usually performed only
for Step 1.

Locating the Equator is no different than if the Sonde was laying flat. It is however necessary to go back
and adjust your location for pinpoint accuracy. !
!
This adjustment is performed only after completing all the steps. In Step 2 you will discover the Sonde is
not laying flat.!

Selecting A Trace Signal Frequency
The choice of 512Hz, 8kHz, 33kHz, 65 kHz and 116kHz Frequency is dependent on the conditions of the locate .!
The 512 Hz, 8 kHz, 33kHz, 65kHz and 116 kHz signals each have their advantages . It is recommended to begin by using
the 8 kHz signal, and continue as long as you are confident in the results . If the signal is very weak try to adjust the
connection or grounding . If there is no improvement in signal then try 33kHz. Repeat adjustments of ground and
connection point again until switching to 116kHz. The 512Hz signal 8 kHz and 33kHz takes the best of both high and low
frequency.!
!
512Hz (lower frequency) !
• Signal is usually preferred for a loop trace. !
• Has a long locating range. !
• Not very susceptible to bleed off or coupling!
• Less likely to jump impedance on the utility than mid-range and high-range frequencies.!
• Susceptible to locating errors caused by nearby high voltage electrical cables (50Hz- 60Hz). !
• Will not travel well through disconnected shield bonds or insulated pipe bushing .!
!
8 kHz (mid-range frequency) 33kHz (high frequency)!
• Less susceptible to locating errors caused by nearby high voltage electrical cables (50Hz- 60Hz).!
• Has a better locating range than higher frequencies.!
• Not very susceptible to bleed off or coupling!
• Less likely to jump impedance on the utility than high-range frequencies.!
• Mid range frequency is not very susceptible to bleed off or coupling but can jump impedance on the utility better than the
512 Hz!
• 8 kHz is one of the most common frequencies used to locate coaxial cable and telecom pairs .!
!
65kHz and 116kHz (high frequency) !
• Less susceptible to locating errors caused by high voltage electrical cables (50Hz- 60Hz) .!
• Locating range is shorter than the 512Hz, 8kHz and 33kHz signal . !
• 65 kHz (higher frequency) is sometimes better than the 8kHz (mid-range frequency) and 33kHz (high frequency) for
locating sharp corners in cables or pipes.!
• 65kHz and 116kHz signal is also better for “jumping” disconnected shield bonds or grounds, or tracing signal may indicate
one of these characteristics. !
• The locating range is quite short for the 116kHz signal so the Transmitter must be repositioned more often during the
tracing operation. !
• High Frequencies are useful for applying a signal using the Inductive Coupler.

SR-1 Precision
Absolute Signal Strength
The SR-1 Precision 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 top of the LCD display. The measurement
range is from 0 to 999 indicating a very week signal (0) to a very strong signal (999). Absolute 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 will not be displayed if the meter reading is. too high or too low. Adjust the GAIN to move the
meter reading to mid-scale.The numerical display will change from ‘---’ to a valid measurement.!
Absolute Signal Strength measurements are more sensitive to signal changes than the meter display PEAKS and NULLS
can be more precisely pin-pointed.This measurement can also be used to monitor signal loss as the conductor is being
traced.
Absolute Signal Strength
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 midscale. Likewise, if the meter reading is very
high, pressing the GAIN down button will center the meter reading to midscale.
Passive 50Hz / 60Hz ~ Locating
The SR-1 Precision Receiver is capable of locating power utility frequencies. This MODE is useful for locating
underground primary and secondary power utilities. In certain circumstances, this MODE will also locate water pipes,
sewer lines, cable television, and telephone.The reason is that common electrical grounds are sometimes found among
these various utilities Select the 50/60~ (Hz) frequency on the receiver. Select 60Hz mode. The SR-1 will locate conductor
using the Sharp PEAK mode.!
This method is useful because of its speed and convenience. Start at a known reference point and keep in mind that other
conductors in the area may produce this same locating signal.!
The SR-1 TX transmitter is not required to locate in this mode.
Passive Radio Frequency Locating
The SR-1 Precision Receiver is capable of passively locating metallic utilities where radio frequencies have coupled to the
utility. This mode is useful for sweeping a green area for utilities. In certain circumstances, this mode will locate water
pipes, cable television, gas lines and telephone. This locating option does not always detect buried utilities even when
radio frequencies are present.This.method is useful because of its speed and convenience. Start at a known reference
point and keep in mind that other conductors in the area may produce this same locating signal .!

SR-1 Precision
Push Button Depth
The only way to be sure of the depth of a utility is to exposes the utility. !
At any given time, the depth readout may be inaccurate.!
!
!
The SR-1 Precision Receiver can measure depth with the push of a button. The depth is displayed at the top of the LCD
display in feet and inches. Push button depth is useful in quickly determining the depth of the utility during path locating.!
Begin this measurement by locating the path of the cable or pipe. Move to the location where you want to measure the
depth. Stay at least 15 feet (4 .6 . meters) away from the SR-1 TX transmitter. Pin-point this location as accurately as
possible (see Peak Mode Locating page, Null Mode Locating page and Absolute Signal Strength page). Place the
receiver vertically over the conductor and rest the foot of the locator on the .ground. While holding the receiver vertical,
press and release the DEPTH.button.The receiver will briefly indicate a measurement is being performed and then display
the depth at the top of the LCD .display.!
!
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 readings. For information on identifying tilted magnetic fields, refer to
Tilted Magnetic Field Identification and Depth Measurement 45º Method.!
!
Note: !
The SR-1 Precision Receiver is designed to alert the operator of potential current and depth measurement errors . If the
display reads ‘Err’ during a current and depth measurement, the receiver has.detected a condition that could produce
inaccurate readings.!
!
!
Errors can exist when the conductor signal flow is too small. Check SR-1 TX transmitter hookup and far end access point
for poor connections. This.cause of error can be identified by a high.GAIN setting (80 or greater on the bar-graph display).!
The receiver may also be detecting adjacent cables or is not directly over the target conductor. Verifying target conductor
path precisely before measuring current again.!
If at anytime the display reads ‘CAL’, .contact EPL Solutions, Inc at (714) 453-9760.
Current Measurement
The SR-1 Precision Receiver later models contain a feature that is very useful in identifying a desired cable in a field of
various conductors and/or utilities. !
It is not unusual for the target conductor (the conductor connected to the SR-1 TX transmitter) to induce a signal into
nearby conductors in a crowded field. In these instances, the radiated signal on the conductors close to the surface of the
earth, may be stronger than the transmitter signal on the target conductor buried deep in the ground. !
The operator will find two or more paths and must determine which is the target conductor. By using the current
measurement feature of the SR-1 Precision Receiver, the operator can determine the amount of 512 Hz, 8kHz, 33kHz
65kHz or 116kHz current flowing on the conductors, regardless of the depth. !
The highest current flow indicates the target conductor.

SR-1 Precision
Tilted Magnetic Field Identification
When adjacent cables or pipes are present, they will sometimes create locating errors. Some of the SR-1 TX transmitter
signal is picked up by the adjacent conductors and is redirected so that it combines with the original signal. The result is a
Tilted Magnetic Field.This is often the reason that numeric depth readouts.are sometimes created in error.!
The operator can verify the accuracy of path locate by performing the 45º Angle Method locate and the Depth
Measurement Calculation. If readings agree to within 5 inches, the path locate is accurate. !
If the two depth readings do not agree, then dig with care A closer locate would be halfway between the two outside
depth locate marks !
This is an important technique that should be used to ensure the most accurate location possible.
Depth Measurement 45º Angle Method
Move to the location you want to measure depth. Stay at least 15 feet away from the SR-1 TX transmitter. With the SR-1
Precision Receiver in Peak Mode sweep the receiver left to right across the path until the utility is located. Mark the path
on the ground as precisely as possible using the Peak Locating Method.!
The Depth measurement 45º Angle Method should be performed at different areas along the path of the utility and is
effective for checking accuracy of location.!
Place the receiver on the ground with.the LCD meter facing up. Position the unit so that the BUBBLE LEVEL (if equipped)
on top of the meter is centered(45º). Pull the receiver away from the cable path (at 90º to the cable path) keeping the
BUBBLE LEVEL (if equipped) centered. When the receiver indicate. a Peak-Null-Peak signal, mark the location of the
receiver’s foot. The distance between the receiver and the cable path is the depth of the pipe or cable.!
A false depth reading may be caused by nearby buried metallic objects, such as a second cable, pipe, sewer, fence or
railroad track. Confirm the depth measurement by repeating. the above steps on the opposite side of the pipe or cable.!
A variance greater than 5 .inches in depth measurement may indicate the presence of additional buried cables, pipes or
other objects.

SR-1 Precision
Depth Measurement Calculation
Move to the location you want to measure depth. Stay at least 15 feet away from the SR-1 TX transmitter. With the SR-1
Precision Receiver in Peak Mode sweep the receiver left to right across the path until the utility is located. Mark the path
on the ground as precisely as possible using the Peak Locating Method.!
The measurement calculation should be performed at different areas along the path of the utility and is effective for
checking location accuracy because it is unlikely to have the signal distortion in each direction of the utility path.!
Adjust the gain up so the bar-graph is at the 100%. Move left of utility until the bar-graph drops to 50% and mark this
point. Perform the same to the right of the utility. They should be about equal distance from center. Measure the distance
from both marks, they should be twice the depth of the utility.

SR-1 Precision
Two-Thirds Plus One Third Rule
When adjacent cables or pipes are present, they will sometimes create locating errors. Some of the SR-1 TX transmitter
signal is picked up by the adjacent conductors and is redirected so that it combines with the original signal. The result is a
Tilted Magnetic Field.This is often the reason that numeric depth readouts are sometimes created in error.!
The operator can verify the accuracy of path locate by performing the Two-Thirds Plus One Third Rule.!
!
Move to the location you want to measure depth. Stay at least 15 feet away from the SR-1 TX transmitter. With the SR-1
Precision Receiver in Peak Mode mark the path on the ground as precisely as possible using the Peak Locating Method.!
With the SR-1 Precision Receiver in Null Mode mark the path on the ground as precisely as possible using the Null
Locating Method.!
If the Peak and Null marks are the agree (in the
precise.!
same location) it can be assumed you location is accurate and
The location is not accurate and precise if the Peak and Null marks do not agree. Both marks will show the error on the
same side of the utility. True utility line position will be close to the peak location. The utility line is half as far to the side of
the peak position as the distance between the
Peak and Null.
