The electronic principle on which radar operates is very similar to the principle of sound-wave reflection. If you shout in the direction of a sound-reflecting object (like a rocky canyon or cave), you will hear an echo. If you know the speed of sound in air, you can then estimate the distance and general direction of the object. The time required for an echo to return can be roughly converted to distance if the speed of sound is known.
Radar uses electromagnetic energy pulses in much the same way, as shown in Figure 1. The radio-frequency (rf) energy is transmitted to and reflected from the reflecting object. A small portion of the reflected energy returns to the radar set. This returned energy is called an ECHO, just as it is in sound terminology. Radar sets use the echo to determine the direction and distance of the reflecting object.
The term RADAR is an acronym made up of the words:
RAdio (Aim) Detecting And Ranging
The term “RADAR” was officially coined as an acronym by U.S. Navy Lieutenant Commander Samuel M. Tucker and F. R. Furth in November 1940. The acronym was by agreement adopted in 1943 by the Allied powers of World War II and thereafter received general international acceptance. [1]
It refers to electronic equipment that detects the presence of objects by using reflected electromagnetic energy. Under some conditions, radar system can measure the direction, height, distance, course, and speed of these objects. The frequency of electromagnetic energy used for radar is unaffected by darkness and also penetrates fog and clouds. This permits radar systems to determine the position of airplanes, ships, or other obstacles that are invisible to the naked eye because of distance, darkness, or weather.
Modern radar can extract widely more information from a target's echo signal than its range. But the calculating of the range by measuring the delay time is one of its most important functions.
Basic design of radar system
The following figure shows the operating principle of a primary radar set. The radar antenna illuminates the target with a microwave signal, which is then reflected and picked up by a receiving device. The electrical signal picked up by the receiving antenna is called echo or return. The radar signal is generated by a powerful transmitter and received by a highly sensitive receiver.
Figure 2: Block diagram of a primary radar
All targets produce a diffuse reflection i.e. it is reflected in a wide number of directions. The reflected signal is also-called scattering. Backscatter is the term given to reflections in the opposite direction to the incident rays.
Radar signals can be displayed on the traditional plan position indicator (PPI) or other more advanced radar display systems. A PPI has a rotating vector with the radar at the origin, which indicates the pointing direction of the antenna and hence the bearing of targets.

3. SECTION I: GENERAL
Introduction
The TraceMaster is the first pipe and cable locator on the market to offer a Remote Link between the
transmitter and the receiver units. This is accomplished through a radio frequency (RF) two-way
communications channel, and makes it possible to change the transmitter frequency from the receiver. The
link also allows the receiver to monitor the transmitter battery status and other operating parameters.
The TraceMaster operates on a passive mode, three different active modes (conductive, inductive and
clamp), and a sonde mode. In the passive mode the transmitter shuts down its output and the receiver
searches for 50/60 Hz signals. In the active modes the transmitter operates at a low frequency (575 Hz), a
mid-range frequency (8 kHz), a high frequency (82 kHz), and a very high frequency (455 kHz). In the
sonde mode the receiver searches for the signal transmitted by a small sonde (either 512 Hz or 82 kHz) that
has been routed through a pipe. The choice of frequencies depends on the specific active mode, as
explained elsewhere in this manual. In addition, the receiver can determine the approximate depth of the
target, and has the ability to operate in manual or automatic gain modes.
Tested to Comply with FCC Standards.
This Class A device complies with Canadian ICES-003

FCC ID: NS999P2 CANADA: 3143 102 1527A
Receiver
The receiver's front panel is designed to be intuitive and require a minimum of training for effective use of
the instrument. The controls and the information display area are large and easy to understand. Yet they
include everything necessary to control and monitor the transmitter remotely.
Controls
MASTER ON/OFF SWITCH - This switch is built into the VOLUME control. When the VOLUME
control is in the full CCW position, past its “click”, power to the unit is removed, and the ON/OFF
TRIGGER SWITCH is disabled. The intention of this switch is to prevent accidental turn on by depression
of the trigger switch when the unit is stowed away.
ON/OFF TRIGGER SWITCH - The trigger switch is located in the handle of the receiver and it applies
power when the unit is picked up and held by the handle. When the trigger is released (the receiver is put
down or stored away), the power is removed from the instrument. There is a 5-second delay to prevent
premature power removal when changing hands or letting the handle go momentarily. This switch helps to
conserve battery power by preventing the user from leaving the power on accidentally.
NOTE: The trigger switch is enabled by the MASTER ON/OFF switch built into the volume control (see
description above).
VOLUME - The volume control adjusts the volume of the tone coming from the speaker. The volume
increases as the control rotates in the CW direction.
4. GAIN - When the gain control is in the full CCW position, past its “click”, the receiver is in the automatic
gain mode. In this mode the receiver adjusts its sensitivity as a function of the strength of the detected
signal. When the control is rotated CW, the receiver is in the manual gain mode. The sensitivity of the
receiver increases as the control rotates in the CW direction.
FREQ - An operating frequency can be selected by depressing this button consecutively until the desired
frequency is indicated on the display of the receiver. The passive mode, sonde modes, and active modes
are accessible via this button.
NOTE: When the FREQ control is depressed, the "Antenna" symbol comes on while the receiver sends the
new frequency command to the transmitter and awaits for confirmation that the frequency has changed.
Because of this, a delay of up to 2-3 seconds will occur before the new operating frequency is indicated on
the display. If the new frequency is not indicated on the display shortly after the "Antenna" symbol goes off,
then try to depress the FREQ control again. See Section III "Operation" for additional hints on operating
the FREQ control.
The TraceMaster comes standard with five operating frequencies:
Passive Frequency - In this mode the transmitter is not active (see note below). The receiver picks up
the AC power (factory selected 50 or 60 Hz) off the buried cables and pipes.
NOTE: The receiver "remembers" the last frequency it was operating at when it was turned off. When
the power to the receiver is restored, you will have to depress the FREQ button to switch away from
the frequency "remembered". If the transmitter power is turned off, the transmitter will not
acknowledge receiving the commands to change frequency, and therefore the receiver will not be able
to change to passive frequency. You will have to temporarily turn the transmitter on to allow it to go
to passive, then you can turn it back off or leave it in the very low-power consuming "passive" mode.
Low Frequency (575 Hz) - This frequency will not jump to adjacent conductors and can only be
induced with the conductive clips connected directly to access points on the utility to be traced.
Mid-range Frequency (8 kHz) - This frequency will not usually jump to adjacent conductors, but may
jump across non-conductive joints in a pipe for longer tracing. It can only be induced with the
conductive clips connected directly to access points on the utility to be traced, or the optional inductive
clamp.
High Frequency (82 kHz) - This frequency can typically jump to adjacent conductors and can be
induced by the conductive clips, the optional inductive clamp, or the built-in inductive antenna.
Very High Frequency (455 kHz) - This frequency can easily jump to adjacent conductors and it is a
good frequency to use for total field survey or "quick scan" of a small area. It can be induced by the
conductive clips , the optional inductive clamp, or the built-in inductive antenna.
NOTE: See Section VII: Sonde Operation, for additional considerations regarding operating
frequency.
DEPTH - To determine the depth of the target place the receiver directly over the target, then press the
depth button. . There is a delay of 2.0 seconds between pressing the depth button and displaying the depth
on the LCD. The measured depth will continue to be displayed on the LCD for as long as the button is
depressed, otherwise (if the button is pressed and quickly released), the depth will show on the LCD for a
few seconds, along with the word "DEPTH" on top of the LCD. Then the LCD will revert back to display
signal strength. The TraceMaster can be factory set to display depth in feet and inches or in meters.
NOTE: See Section VII: Sonde Operation, for additional considerations regarding depth measurements
when using a sonde.
5. NOTE: Depth is not available at 455 kHz.
NOTE: The DEPTH button can also be used on power up to
"defeat the RF link". See Section III "Operation" for details.
LCD Display
The LCD display has five general areas to display information to
the user: a Receiver (RX) Window, a Transmitter (TX) Window,
a Frequency Indicator, a Direction Indicator, and a Numeric
Display.
The TraceMaster has an ambient light sensor located right under
the "s" of the word "TraceMaster". Under very dim or dark
lighting conditions, this sensor activates backlighting of the
LCD to improve readability.
RX WINDOW - This window groups a symbol (battery) and a
legend concerning the receiver status.
The "Battery" symbol indicates the receiver's battery status as follows: when all 3 segments inside the
battery symbol are present, the battery is fully charged. When only 2 segments are present the battery
has a medium charge. A single segment present signals a low battery. Always replace the receiver
batteries when only the bottom segment is visible.
NOTE: IF THE BATTERY LEVEL GOES BELOW THE LEVEL INDICATED BY A SINGLE
SEGMENT, ALL 3 SEGMENTS WILL START TO FLASH, AND THE RF LINK WILL BE
DISABLED.
The "AUTO GAIN" legend indicates when the gain is in the automatic mode. If the legend is not
visible the receiver is operating in the manual gain mode.
TX WINDOW - This window groups three symbols concerning the transmitter status. These symbols are
automatically updated via the RF link every 10 seconds.
The "Battery" symbol indicates the transmitter's battery status as follows: when all 3
segments inside the battery symbol are present, the battery is fully charged. When
only 2 segments are present the battery has a medium charge. A single segment
present signals a low battery. Always replace the transmitter batteries when only the
bottom segment is visible.
The "Inductive Mode" symbol indicates that the transmitter is operating in the
inductive mode. If the symbol is not visible the transmitter is operating in either the
conductive or the clamp mode because the conductive clips or the optional inductive
clamp are plugged into the transmitter's jack. For additional information on how to
switch modes see the transmitter section.
The "Antenna" symbol indicates that the receiver is attempting to communicate with
the transmitter via the RF link. It comes on briefly each time the FREQ switch is
depressed, and also every 10 seconds to request a status update from the transmitter.
NOTE: The "Antenna" symbol should only come on for a brief period and then go off. This is an
indication of a good communications link with the transmitter. If it stays on longer (up to about 3
seconds), the communications link with the transmitter is poor or non-existent. See also Section III -
Operation - "Defeating the RF Link".
6. FREQUENCY INDICATOR - When a dot appears to the left of a given frequency, that frequency is active
in the receiver and the transmitter. When the receiver operates in the sonde mode two dots will appear,
one to the left of the "Passive" legend and one to the left of the sonde's operating frequency. See Section
VII: Sonde Operation, for additional information.
NOTE: In the passive mode the transmitter is not active. However, a dot next to the "Passive" indicator on
the LCD means that the transmitter has successfully received the command to go "inactive".
DIRECTION INDICATOR - The purpose of the arrows and center bar in this indicator is to tell the
operator in which direction to move the receiver in order to be directly over the target.
Right Arrow - Receiver should be moved to the right to get closer to the target.
Left Arrow - Receiver should be moved to the left to get closer to the target.
BOTH ARROWS and BAR - Receiver is placed directly over the target. This
is also accompanied by a beeping sound.
NOTE: When all three elements of this indicator are OFF, the signal strength is not adequate to make
a directional determination. Keep searching based on the signal strength indication (see below) and
the audio feedback, until one of the arrows comes ON. Directional indication is not available at 455
kHz.
NUMERIC DISPLAY - The numeric display consists of 3 ½ digits (the half-digit can only be a "1" or be
off) and it is used to display signal strength, depth, and transmitter output current.
Signal Strength - This is an indication of the relative signal level detected by the receiver and is a
function of the gain setting. Good signal strength will typically be between 20 and 80, however see
also Section III - Operation - "Gain", for a better understanding on how to interpret the signal strength
readings.
Depth Reading - When measuring depth the word DEPTH lights up above the numeric display. Then,
after the calculation is done, the depth of the target in feet and inches (or meters) is displayed
as shown below for as long as the button remains depressed, or for just a few seconds if the button was
pressed and released:
12 4 or (factory set) 4.10
FT IN m
Transmitter Ouput Current - If the transmitter is in conductive mode and operating at 575 Hz, 8 kHz,
or 82 kHz frequency, the transmitter will measure the amount of current being deliverd through the
conductive clip when the “SHOW STATUS” switch is depressed. Then, upon receiving the next status
request from the receiver via the remote link, the transmitter will send the value of the current
measured in mA (milliamperes). This value will be displayed momentarily on the receiver’s display.
NOTE: There is no current measured for Passive, any of the clamp modes, any of the inductive mode
frequencies or the conductive mode at 455 kHz.
7. Speaker
An audible indication of signal strength is also provided. The pitch of the sound will increase with
increasing signal strength. However, the volume is determined only by the VOLUME control. See Section
III - "Operation" - "Gain"- for additional hints on the effective use of the signal strength indicators.
Transmitter
The transmitter's frequency setting is performed automatically via the RF link at the receiver. The user
needs only to plug in the conductive clips, optional inductive clamp, or nothing (to operate in inductive
mode), then turn the transmitter ON. Turning the transmitter ON/OFF cannot be performed remotely from
the receiver.
Controls
With only three controls plus the ability to change frequencies from the receiver, the TraceMaster's
transmitter is very simple to operate.
ON/OFF - This is a momentary push-button switch that toggles the power to the transmitter on and off.
When power to the transmitter is ON, the nearby green LED will illuminate and remain ON.
NOTE: The ON/OFF switch needs to be pressed until the green LED illuminates, then released, to turn the
unit ON. Press the switch again until the green LED goes off to turn the unit OFF
NOTE: Power to the transmitter must be ON before the receiver is able to communicate with the
transmitter through the RF Link.
SHOW STATUS - In order to conserve battery power all LED's (except "Power ON" and “Battery”)
remain OFF unless this switch is pressed (see LED Indicators section). Press and hold this switch to
display LED indicators. In addition, when this switch is pressed and the transmitter is in conductive mode
and operating at 575 Hz, 8 kHz or 82 kHz frequency, the transmitter will measure the amount of current
being delivered through the conductive clips. When the receiver requests the status of the transmitter via
the remote link for the first time after pressing this switch (remember that the receiver interrogates the
transmitter every 10 seconds); the transmitter will include the value of the current measured in its response.
The value will subsequently be temporarily displayed on the receiver's LCD. See Receiver/LCD
Display/NUMERIC DISPLAY section for additional information.
SELECT - Press to manually select an operating frequency or to place the transmitter in the "Passive"
mode. Each press advances the frequency/mode as follows: Passive >> 575 Hz >> 8 kHz >> 82 kHz >>
455 kHz >> Passive, and so on. However, in induction mode the 575 Hz frequency and the 8 kHz
frequency are skipped (there is no induction mode at these frequencies). In addition, while using the
optional inductive clamp all frequencies not supported by the clamp will be skipped.
NOTE: The only reason to use the manual selection of a frequency is in the event a remote link with the
receiver fails to be established due to environment conditions (distance, obstacles, etc.), or a broken RF
antenna. When the remote link is established it ALWAYS takes precedence over the manual selection. In
some cases it is necessary to press the FREQ control in the receiver to synchronize the receiver and
transmitter units. See Section III "Operation" for additional hints.
LED Indicators
The transmitter has three LED Indicator sections on the front panel. They are labeled REMOTE,
FREQUENCY, and STATUS/MODE. In order to see these indicators the "SHOW STATUS" button must
be pressed and held, as explained in the previous section. The only exception to that rule is when the
8. SELECT button is pressed to select a new frequency. In that case the LED corresponding to the new
frequency will light up GREEN while the SELECT button is pressed.
NOTE: To conserve battery power, and because of the fact that the RF link allows the information the user
needs to know about the transmitter to be displayed on the receiver's display, the LED's are relatively dim,
especially under bright lighting conditions. Usually a hand shade is all that is needed to adequately see the
LED's.
REMOTE - The single indicator in this section is labeled "Link". It will glow GREEN every time a
successful "status request" is received from the receiver. It will glow RED when more than 20 seconds
have passed without receiving a successful "status request" from the receiver.
FREQUENCY - One of the five (5) indicators in this section will glow GREEN to indicate the current
operating frequency.
STATUS/MODE - There are four (4) indicators in this section providing information about the operating
mode and status of the transmitter battery. They are:
CONDUCTIVE/CLAMP - This LED will glow GREEN when the conductive clips or an optional
inductive clamp is plugged into the jack (see Transmitter Jack section), and the transmitter is not in
passive mode.
OUTPUT POWER - This LED provides a rough indication of how good a circuit the transmitter is
hooked to, by attempting to measure the impedance range. It is only meaningful when the transmitter
is in conductive mode, ignore it in any other operating mode. It will glow as follows:
GREEN when the circuit is very good, which typically means the impedance is below 2 kohms;
GREEN & RED, alternating when the circuit is of medium quality, which typically means the
impedance is between 2 and 4 kohms.
RED when the circuit is poor, which typically means the impedance is higher than 4 kohms.
NOTE: If the indicator is RED or alternating GREEN & RED, you should try to improve the
connection (check the cables, the clips, the ground stake, wet the ground, clean rust or dirt, etc.).
However, in many cases the reason for the high impedance is the soil itself (sandy or very dry) and/or
the composition of the pipe or cable you are trying to trace (cast iron pipes, rusted or broken wires,
heavy insulation to ground, etc.), and you may not be able to improve the connection. This DOES NOT
MEAN that you won't be able to locate, it just means that there is a smaller amount of current
circulating in the circuit and you may have to increase your receiver gain, or not be able to trace the
signal as far as you would with a higher current.
NOTE: If the transmitter is in conductive mode and operating at 575 Hz, 8 kHz or 82 kHz frequency,
the current measurement feature can provide a better indication of how good a circuit the transmitter
is hooked up to. See Receiver/LCD Display/NUMERIC DISPLAY and Transmitter/Controls/SHOW
STAUS sections, as well as Section III: Operation & Accessories for additional information on the
current measurement feature
INDUCTIVE - This LED will glow GREEN when there is nothing plugged into the transmitter jack
and the transmitter is NOT in Passive Mode Therefore the transmitter is emitting its signal via the
built-in induction antenna.
BATTERY - This LED will glow GREEN when the battery is fully charged. It will glow RED when
the battery has a medium charge, and it will flash RED when the battery voltage reaches a level where
the batteries must be replaced. Always replace the transmitter batteries when this LED is flashing
RED. It is not necessary to press “SHOW STATUS” to see this LED.
9. NOTE: Certain operating modes and/or frequencies tax the batteries more than others. It is possible
for the battery indicator to indicate different levels of charge while operating in different
modes/frequencies. If the LED flashes RED consistently in most operating modes the batteries should
be replaced.
Transmitter Jack
This jack is used to connect the conductive clips or the optional inductive clamp to the transmitter. The
unit automatically detects what accessory has been plugged in and adjusts its operation and indicators
accordingly.
NOTE: It is recommended that you turn the transmitter's power OFF before removing or inserting
accessories from/into the jack.
WARNING
DO NOT CONNECT CONDUCTIVE CLIPS TO LIVE POWER LINES! THIS IS A HAZARDOUS
PRACTICE AND CAN PERMANENTLY DAMAGE THE TRANSMITTER. IF YOU ARE
CONNECTING TO DEAD POWER LINES, MAKE PROVISIONS TO AVOID ACCIDENTAL
ACTIVATION OF POWER TO THE LINES.
Transmitter Time Out
The transmitter will turn itself off after approximately 85 minutes without receiving a status request from
the receiver via the RF Link.
Car Battery Adapter (optional)
Power your TraceMaster transmitter from your auto battery. (Requires factory upgrade of transmitter, if
not ordered with a new unit.)
The car adapter plugs into the cigarette lighter receptacle of your vehicle and it is equipped with an LED
that will light up when 12V are present. Please note that in some vehicles the ignition switch needs to be
on for power to be available to the cigarette lighter receptacle. The other end of the cable plugs into a
receptacle inside the storage compartment of the TraceMaster Transmitter.
The coiled cable allows you to place the TraceMaster Transmitter up to approximately 15 feet from the
vehicle. Do not overextend the cable.
The adapter can be plugged in with or without batteries installed in the TraceMaster Transmitter unit, but it
is recommended that the Transmitter be turned off.

11. SECTION III : OPERATION & ACCESSORIES
Operation
1) Determine which is the best method to induce the transmitted signal into the cable or pipe. The
choices are one of the active modes (conductive, inductive, or inductive clamp) or the passive mode.
Technically in the passive mode the signal is not transmitted by the TraceMaster’s transmitter, but it is
already there due to AC power lines. Whenever possible use the conductive mode, which provides
the strongest and best coupled signal.
2) For Conductive Mode plug the conductive clips into the transmitter jack BEFORE TURNING THE
POWER ON. Connect the red clip to the access point for the cable or pipe. Connect the black clip to
the ground stake, which should be buried on a line perpendicular to the utility to be traced and as far
from it as possible.
3) For Inductive Mode make sure nothing is plugged into the transmitter jack. It is recommended that the
conductive clips or the inductive clamp be removed while the transmitter power is OFF. Place the
transmitter case over the buried cable or pipe in the direction indicated by the arrows on the transmitter
case.
4) For the optional Inductive Clamp Mode insert the plug into the transmitter jack BEFORE TURNING
THE POWER ON, open the jaws of the clamp and place it so that it completely encircles the desired
cable or pipe. Make sure the clamp can fully close so that both ends touch.
5) For Passive mode it is not necessary to turn the transmitter on. However, the receiver always
remembers the last frequency it was operating at when it was turned off. Therefore it is possible for the
receiver to power up in a frequency other than "Passive". If that is the case it is necessary to turn the
transmitter on to allow the RF link to be established and the receiver frequency to be changed to
"Passive". Alternatively, the RF link can be defeated as explained later in this section.
6) Turn on the transmitter power by pressing the ON/OFF button on the transmitter and waiting for the
power on indicator to glow.
7) Verify that you are operating in the desired operating mode by pressing and holding the "SHOW
STATUS" button on the transmitter and observing the STATUS/MODE LED's.
8) Verify that you have a good circuit by checking the output power LED as described in the “LED
Indicator” section.
9) Make sure the master ON/OFF switch built-in the volume control is ON, and pick up the receiver by
its handle. The hand pressure action on the trigger switch will turn its power ON.
10) Fold up the transmitter's RF antenna so that it is perpendicular to the panel. Make sure the receiver's
RF antenna is also in the vertical position.
11) Verify that you have established a good remote link by observing the antenna symbol on the receiver's
LCD display and the "Link" LED indicator on the transmitter front panel (remember to press and hold
the "SHOW STATUS" button). The "Link" LED should glow green after 10 seconds, indicating that
you have established a link with the receiver.
NOTE: Depress the FREQ control on the receiver a couple of times, as described in Section II, to
verify correct operation of the RF link.
12) Frequency changes - The frequency of both the receiver and the transmitter can be changed from the
receiver by pressing the FREQ button on the receiver. Alternatively the SELECT button on the
transmitter can be used to manually select the frequency, but after the first status request from the
12. receiver, the remote link will always cause the transmitter's frequency to revert back to the frequency
selected by the receiver.
NOTE: Selecting the "Passive" mode on the receiver and the transmitter (via the RF link or manually)
will render the transmitter inactive (except for the RF link) and provide transmitter battery savings.
See item 5 above for further details.
13) Gain - When the gain control is in the fully CCW direction, the gain is set automatically. For best
results, the experienced operator has the option to set the gain manually by rotating the control in the
CW direction, beyond the "click". As the control is rotated in the CW direction, the gain increases. As
a guideline, always operate at the minimum gain that shows a clear "peak" over the target. It is not
important what the signal strength number is at the peak, as long as it clearly decreases on each side of
the target. It is NOT necessary to operate with a signal strength close to 99, in fact, if "99" appears on
the numeric display, the signal is saturating the amplifiers and the gain should be reduced. For best
results keep between 20 and 80.
14) Locating Target with arrows - As the operator moves toward the buried target, one of the arrows will
indicate in which direction to move. If the operator moves beyond the target, the other arrow will
indicate that the operator should reverse direction. When the operator is right over the target the tone
will reach maximum pitch and the digital reading will reach a maximum. Both arrows and the center
bar on the display will be ON, and the receiver will start beeping.
NOTE: Directional indication is not available at the 455 kHz frequency.
15) Depth Measurement - Place the bottom of the arrow against the ground, and then push and hold the
DEPTH button. The digital display will indicate the approximate depth. The reading will show as
long as the button is depressed.
NOTE: Depth is not available at the 455 kHz frequency.
16) Defeating the RF Link - It is possible to defeat the RF link to allow the setting of the receiver and
transmitter frequencies independently. This may be needed in situations where the environment
prevents a reliable RF link to be established or if there is a need to operate in passive mode without a
transmitter and the receiver powers up in a different mode, as explained in item 5 above. The RF link
can be toggled between active and defeated by the following sequence:
a- Turn master ON/OFF switch off (click CCW)
b- Hold the unit by the handle so that the trigger is activated
c- Press and hold both the DEPTH and the FREQ controls before you turn
the master ON/OFF switch CW.
NOTE: The antenna symbol will blink continuously while the RF link is defeated. Each time the unit is
turned on with the DEPTH button depressed, it alternates between operating with the RF link active
and operating with the RF link defeated. In other words, repeating the procedure above will re-enable
the RF Link.
17) Using the Current Measurement Feature - The current measurement feature allows the user to know
the amount of current that the transmitter is delivering to the load. The load is everything connected
between the red and black connectors of the conductive clips. In general, larger currents flowing
through the pipes or cables being located will result in longer tracing distances and/or deeper targets
found. However, there is no quick recipe for the amount of current that works best for a particular
situation. The TraceMaster can display currents from 0 to 99 mA, and the usefulness of the feature is
in helping to improve the circuit so that as much current as possible flows through it, this can be done
by improving ground connections, placement of the clips, or even changing frequencies.
13. Since the transmitter does not have a display, it uses the remote link to send the information about the
output current measured to the receiver for displaying purposes. The measurement is triggered by
depressing the Show Status switch, and is received by the receiver when it next requests the status via
the remote link (up to 10 seconds after depressing the switch). The feature is only available in the
conductive mode at 575 Hz, 8 kHz and 82 kHz.

16. SECTION VII: SONDE OPERATION
(You must have a Schonstedt Sonde for this option)
Introduction
If your TraceMaster unit is fitted with the sonde option then it supports the detection of of one or more of
thses sondes:
- Schonstedt's 512 Hz sonde
- 512 Hz sondes from any other manufacturer
- Schonstedt's 82 kHz sonde
These types of sondes are usually attached to devices that are sent through sewer pipes or water pipes. The
emmitted frequency penetratres the walls of such pipes.
Since the signal being traced by the receiver is produced by the sonde, and not travelling along the pipes,
there are some differences in the way the receiver is used. The following section explains how to use the
Tracemaster receiver for sonde operation.
Setting the Receiver for Sonde Mode
How you set your receiver for sonde operation will vary
slightly depending on whether you have purchased a
receiver-only unit or a complete TraceMaster unit
(receiver and transmitter). In both cases, you will know
you are in the sonde mode because the dot next to the
"PASSIVE" and the dot next to another frequency legend
on the display will BOTH be lit, as shown in the figure
below. The frequency legend with a dot next to it will
either be 575 Hz (for a 512 Hz sonde) or 82 kHz (for an
82 kHz sonde).
Receiver Only Unit or Receiver Without RF Link
If your TraceMaster is a "Passive Only", or "Passive + 1 active Frequency", pressing the "FREQ" button
will cycle through the "Passive" mode, "Sonde" modes and the single frequency (if present). That simple!
Receiver with Transmitter and Multiple Frequencies
To use the sonde mode, first make sure the RF link is disabled--(see page 15). If the RF link is not disabled
you can still access the sonde mode(s), even if the transmitter is off, but you will not be able to then switch
to another active frequency or the passive mode, if the transmitter remains off. Access the sonde mode by
pressing the "FREQ" switch a few times, until the dots next to the "Passive" and the "575 Hz" legends on
the display are BOTH lit.
NOTE: Make sure to re-enable the RF link when you are finished with the Sonde Mode.
17. Searching for the Sonde
Due to the nature and strength of the sonde signal, it is necessary to have some idea of where the sonde is,
to narrow the search area to a circle of several feet radius centered at the sonde. This is usually not much of
a problem, since the sonde is "guided" by a device under control of the work crew, often with a camera
attached to it.
Once in the surroundings of the sonde, it is important to differentiate whether you are positioned along the
axis of the sonde (the direction of the pipe) or off to either side. In the sonde mode the arrows are not
functional, so the signal strength is the only indication available, and it will be "null" (very close to zero) if
the receiver is placed on the axis of the sonde with the plane of the sensors perpendicular to it. Move away
from the axis and follow the direction that results in increasing signal strength. Rotate the receiver back
and forth and move in the direction that produces the maximum. As the receiver gets closer to the sonde
the signal strength increases to a maximum when directly over the sonde, if the plane of the sensors is
parallel to the axis of the sonde (approaching from a direction that is perpendicular to the direction of the
pipe). A rotation of 90 degrees from this position should produce a null.
Measuring Depth
To measure depth simply place the tip of the unit on the ground and press the DEPTH button when the
signal strength is at a maximum. The achievable depth depends on a number of factors, but typically it is
possible to read depth up to 5 to 8 feet.
