Description
The RIDGID®A-Frame Fault Locator is a highly
sensitive transmitter and receiver specifically
designed to detect the location of a path to
ground fault (Direct Fault Finding (DFF)) in
the insulation of a buried conductor (such as a
wire or cable). Damaged insulation, severed
conductor, and other faults with ground leak-
age are easily and precisely located.
Model FT-103 Transmitter connects to the insu-
lated conductor and establishes a current flow,
the current leaks to ground through the insula-
tion fault and back to the ground stake. Model
FR-30 Receiver detects the current flow to
ground through the insulation fault. The re-
ceiver provides audio and visual indications of
both signal strength and direction to assist in
detecting and locating the fault. For the A-
Frame fault detector to work, the conductor
must be in contact with the earth – it will not
work with conductors in conduit.
Additionally, the transmitter can be used to
apply a signal to the conductor for path locat-
ing with other receivers, such as RIDGID
SeekTech®or NaviTrack®Locators. This can be
done by direct connect and inductive methods.
Multiple frequencies and power levels are pro-
vided.

Model FT-103 Transmitter and Model FR-30
Receiver are used for fault locating of con-
ductors through direct connect method.
The Model FT-103 Transmitter only can be
used for path locating with RIDGID SeekTech®
and NaviTrack®Locators. This can be done by
direct connect and inductive methods.
1. Confirm have appropriate work area (See
Ge eral Safety Rules). Operate in clear,
level, stable, dry location.Do not use trans-
mitter while standing in water.
2. Determine the correct equipment for the
application, see Descriptio and Specifi -
catio s sections.
3. Make sure all equipment has been in-
spected and set up as directed in their in-
structions.
F ult Loc ting
It is good practice to locate the conductor path
before attempting to fault locate. This can be
done using a variety of RIDGID locating equip-
ment. If during the location of the conductor
path an unusual amount of signal loss occurs,
this may give some indication of the conductor
insulation fault location. Additionally, use visual
cues and past history to aid in identifying the
conductor path and potential fault locations.
Once the conductor path is determined, the
RIDGID FT-103 Transmitter and FR-30 A-Frame
Receiver can be used to locate ground faults in
the insulated conductor. The Model FT-103
Transmitter connects to the insulated conductor
and establishes a current flow, the current
leaks to ground through the insulation fault
A-Frame Fault Locator
999-995-095.10_REV. A
8
and back to the ground stake. The Model FR-30
Receiver detects the current flow to ground
through the insulation fault. For the A-Frame
fault detector to work, the conductor must be in
contact with the earth – it will not work with con-
ductors in conduit. Generally, the A-Frame Fault
Locator works best in earth. Use with gravel,
asphalt, concrete or other ground covers may
not work as well.
The signal strength at the fault depends on
the amount of current leaking there. The greater
the leakage, the greater the signal strength.
Connecting Tr nsmitter
1. Disconnect all loads and grounds from
the conductor to be tested and all neigh-
boring conductors to prevent damage from
high voltage and false reading. Both ends
should be known and disconnected. Dis -
connecting both ends of the conductor
forces all of the transmitter signal through
the fault, improving the fault locate.
2. Insert supplied ground stake into the earth.
Ideally, the ground stake should be in line
with the conductor, 3' to 6' (1m to 2m)
from the end. If conditions require, the
ground stake can be placed to the side of
the conductor. Do not to place the ground
stake over the conductor. It is not recom-
mended to use other existing grounds,
existing grounds may result in signal being
inadvertently applied to non-target cables.
A good ground results in a stronger tracing
signal. To get a good ground, insert the
ground stake as far as possible into the
earth. Moist earth will give a better ground
than dry earth. Wetting the earth around
the ground stake can improve grounding.
This lowers the resistance of the circuit.
While moist earth around the ground stake
improves the circuit, do not use the trans-
mitter in areas that are wet, this can in-
crease the risk of electrical shock.
3. Make sure that the transmitter is OFF.
4. Connect BLACK test lead to the ground
stake. Always connect to the ground stake
first.
5. Connect the BLACK and RED test leads
to the Transmitter.
6. Connect the RED test lead to the conduc-
tor to be tested (see Figure 9).

Loc ting
1. Make sure that no one is near or touching
the conductor, transmitter, leads or ground
stake. Press the ON/OFF button on the
transmitter to turn the transmitter ON.
When the transmitter is turned on, it is set
to the last used frequency. If needed,
press the frequency button on the trans-
mitter until “dFF” is shown on screen
(Figure 9).
Figure 9 – Transmitter Screen
Adjust the signal power by pressing the signal
power button to cycle through the settings (low,
medium and high). Using high power may re-
sult in signal going to ground at non-target
points, low power may mean a circuit is not cre-
ated. The transmitter will display circuit resist-
ance (O MS) at the bottom of the LCD. The
lower the resistance the better the locate signal.
To improve the circuit, improve the ground,
check the lead connections or increase the
power.
The transmitter will continuously beep when
there is a circuit. The lower the circuit resist-
ance, the quicker the beep. The transmitter
will beep three times and a pause (repeat-
ing) if there is no circuit.
If the transmitter display shows voltage warn-
ing (Figure 3), the transmitter is connected to
live voltage. If this happens, DO NOT TOUCH

THE TRANSMITTER, EADS OR CONNEC-
TIONS. The target conductor is energized and
there is the risk of electrical shock. Use high
voltage precautions to disconnect.
2. When fault locating, generally the receiver
should be used over the conductor, with
the front receiver spike towards the ex-
pected fault and the rear receiver spike to-
wards the ground stake. The receiver
spikes should evenly penetrate the earth
to make good electrical contact. The cur-
rent flowing in and out of the ground
spikes supplies the signal to locate the in-
sulation fault (see Figure 10).
Figure 10 – Receiver Positioning
3. To start the locate, place the A-Frame
receiver between the ground stake and
the transmitter connection to the conduc-
tor. Press the A-Frame Receiver ON/OFF
button to turn receiver ON.
The signal strength will appear on the
receiver display. Signal strength will be the
highest near the ground stake and at
faults. Press the “Ref” button to store a ref-
erence signal strength near the ground
stake.
The receiver display arrows will indicate
the direction of the fault. Fault direction is
also indicated audibly - a long slow beep
indicates forward direction and a quick
beep indicates backward direction.

4. Remove the receiver from the earth and
move several steps as indicated by the
directional arrow and beeping along the
conductor path. Reinsert the receiver
spikes into the earth (Figure 11).
Continue moving away from the ground
stake along the conductor path. Signal
strength should drop (in some cases going
to zero) and then rise as you move to-
wards a fault.
5. Signal strength will peak over the fault. If
you pass the fault, the directional arrow will
change direction and the beep will change
from long slow to quick beep and the sig-
nal strength will decrease. Continue to
move the receiver back and forth until
slight movement causes the directional
arrows and beeping to toggle back and
forth. At this point, the fault is centered be-
tween the spikes of the receiver.
Compare the signal strength to the refer-
ence signal strength taken near the
ground stake. They should be similar. If the
fault signal strength is much lower than the
reference value, you may not have lo-
cated a fault. For instance, a grounded
splice point would behave as a fault during
the locate, but would give a much lower
signal strength. For a low fault signal
strength, you may want to mark the loca-
tion and continue down the conductor
path looking for a fault signal strength
closer to the reference signal.
Once a fault is located with a signal similar
to the reference signal, turn the A-Frame
Locator perpendicular to the path of the
conductor. Move the receiver back and
forth until slight movement causes the di-
rectional arrows and beeping to toggle
back and forth. At this point, the fault is
centered between the spikes of the re-
ceiver. See Figure 12. Mark the location of
the fault.
6. Once the locating is completed, press the
ON/OFF button to turn the transmitter OFF.
Always turn the unit OFF before discon-
necting the cable leads to reduce the risk
of electrical shock. Remove the cable lead
from the target conductor first. Always dis-
connect the cable lead from the target
conductor first before removing the cable
lead from the ground spike to reduce the
risk of electrical shock. Disconnect the
cable lead from the ground spike.
Loc ting Below P ved
Surf ces
Locating can be difficult if the fault is below a
paved surface, because the receiver spikes
cannot make good electrical contact with
the earth. In this case, there are several
methods that can be used.

• If the paved area is relatively small, the
receiver can be used around the periphery
of the area. The receiver can be rotated
side to side, and where the receiver di-
rectional arrows and beeping toggle back
and forth, extend a straight line perpendicu-
lar to the center of the A-Frame Receiver.
Do this in several locations around the
suspected fault area. The straight lines
should all intersect at the same point. This
is the location of the fault. This method of
locating is less exact than placing the re-
ceiver directly over the conductor. See
Figure 13.
• An alternate way to locate below paved
surfaces is to improve the conductivity be-
tween the pavement and the receiver with
water. One method is to attach sponges to
the spikes of the receiver. Wet the sponges
with water and keep wet. Conduct the fault
locate normally.
• Another method is to wet the surface of the
pavement with water and conduct the fault
locate normally. Do not do this in the area
of the transmitter – this increases the risk of
electrical shock.
Figure 13 – ocating below paved surfaces
Multiple F ults
If there are multiple faults in the conductor,
the faults will have signals proportional to
the amount of current leaking. The locate is
done the same as for a single fault, but the
signal strength will not be as strong. Typically,
the largest fault (least resistance fault) is
easiest to find. Best practice is to find and re-
pair the first fault and continue the locate
for other faults.
P th Loc ting
The FT-103 Transmitter can be used with other
commercially available receivers (such as the
RIDGID SeekTech or NaviTrack receivers) to
path locate conductors. The FT-103 transmitter
can be used to apply an active tracing signal to
a conductor in three ways:
• Direct Connect – The transmitter’s leads
are connected directly to the target conduc-
tor and a suitable ground. This method is
most commonly used when the target util-
ity is accessible. Direct connect should not
be used for energized (live) conductors.
• Inductive Clamp (optional equipment) –
the jaws of the inductive clamp encircle
the target conductor; if the conductor is in-
sulated, there is no metal to metal contact.
This method is commonly used when the
target utility is accessible but direct con-
nect is not possible on an insulated cable.
• Broadcast Inductive Mode – The transmit-
ter generates a field, which in turn induces
a current in the target conductor. There is no
direct connection between the transmitter
and the target conductor. The transmitter is
placed over and inline with the target con-
ductor. The transmitter’s internal antenna in-
duces a signal onto the target conductor.
This method is most commonly used when
the target utility is not accessible.
Disconnect all loads from the conductor to
be tested and all neighboring conductors to
prevent damage from high voltage and false
reading.
Direct Connect P th Loc ting
Method
1. Insert supplied ground stake into the
earth. Or, if other good grounds are avail-
able in the area, they can be used.
A good ground results in a stronger tracing
signal. To get a good ground, insert the
ground stake as far as possible into the
earth. Moist earth will give a better ground
than dry earth. Wetting the earth around
the ground stake can improve grounding.
This lowers the resistance of the circuit.
While moist earth around the ground
stake improves the circuit, do not use the
transmitter in areas that are wet, this can
increase the risk of electrical shock.
The far end of the conductor should be
grounded.
2. Make sure that the transmitter is OFF.
3. Connect BLACK test lead to the ground
stake. Always connect to the ground stake
first.
4. Connect the BLACK and RED test leads
to the Transmitter.

5. Connect the RED test lead to the conduc-
tor to be tested.
6. Press the ON/OFF button to turn the trans-
mitter ON. When the transmitter is turned
on, it is set to the last used frequency.
Press the frequency selection button to
cycle through frequency settings to the
desired locating frequency.
Adjust the signal power by pressing the
signal power button to cycle through the
settings (low, medium and high). Using
high power can couple into non-target
conductors, low power may mean a circuit
is not created. The transmitter will display
circuit resistance (O MS) at the bottom of
the LCD. The lower the resistance the bet-
ter the locate signal. To improve the circuit,
improve the ground, check the lead con-
nections, increase power or change the
frequency.
If the transmitter display shows voltage
warning (Figure 3), the transmitter is con-
nected to live voltage. If this happens,
DO NOT TOUCH THE TRANSMITTER,
EADS OR CONNECTIONS. The tar-
get conductor is energized and there is
the risk of electrical shock. Use high volt-
age precautions to disconnect.
7. Check the circuit and adjust signal power,
grounding or connections to ensure locat-
able field.
8. Turn ON the receiver/locator and follow
the instructions for the receiver. Make sure
the receiver’s frequency is set to match that
on the transmitter. Confirm the receiver is
picking up the transmitted frequency by
holding it near the transmitter and observ-
ing the increase in receiver signal.
9. Once the locating is completed, press the
ON/OFF button to turn the transmitter
OFF. Always turn the unit OFF before dis-
connecting the cable leads to reduce the
risk of electrical shock. Remove the cable
lead from the target conductor first. Always
disconnect the cable lead from the target
conductor first before removing the cable
lead from the ground spike to reduce the
risk of electrical shock. Disconnect the
cable lead from the ground spike.

all instruction for the use of the inductive
clamp.
2. Insert the plug of the inductive clamp
into transmitter (see Figure 2).
3. Clamp the jaws of the inductive clamp
around the target conductor. Make sure
that the jaws of the clamp are fully closed.
(See Figure 14). Both ends of the conduc-
tor should be grounded for best results.

4. Press the ON/OFF button to turn the trans -
mitter ON. When the clamp is plugged in
the clamp symbol ( ) shows on the
screen and only clamp frequencies are
available. Press the frequency selection
button to cycle through frequency settings
to the desired locating frequency. Adjust
the signal power by pressing the signal
power button to cycle through the settings
(low, medium and high). The inductive
clamp typically works best with frequen-
cies around 8k z, 33 k z, 93k z.
5. Check the circuit and adjust signal strength
(see Figure 3, Circuit I formatio ).
6. Turn ON the receiver/locator and follow
the instructions for the receiver. Make
sure the receiver’s frequency is set to
match that on the transmitter. Confirm
the receiver is picking up the transmitted
frequency by holding it near the trans-
mitter and observing the increase in re-
ceiver signal.
7. Once the locating is completed, press
the ON/OFF button to turn the transmitter

shift transmitter into
broadcast inductive
mode. Broadcast in-
ductive icon ( ) ap-
pears on screen and
the transmitter will
start beeping to indi-
cate that it is operat-
ing.
Adjust the signal power by pressing the
signal power button to cycle through the
settings (low, medium and high) and
choose high. Press the frequency selec-
tion button to cycle through 33khz and
93k z frequency settings to the desired
locating frequency. When using Broadcast
Inductive Mode, higher frequencies tend
to get a better signal at the receiver.
3. Turn ON the locator and follow its instruc-
tions. Make sure to set the receiver to
the same frequency as the transmitter.
Figure 16 – Orientation to the ine – Inductive
Mode
When the transmitter is in broadcast induc-
tive mode, it generates a field around the
transmitter. This field is in both the ground
(towards the target conductor) and into
the air around the transmitter. When the re-
ceiver is within approximately 30 feet (10
meters) of the transmitter, it will measure
the field directly from the transmitter and
not the signal induced on the target con-
ductor. This is called “Air Coup ling”. Operate
the receiver at least 30 feet from the trans-
mitter to prevent this. (See Figure 16).
One way to confirm that you are tracing the
target conductor and not the transmitter
field is to look for a strong, stable prox imity
signal and a valid depth measurement on
the receiver. While directly over the ener-
gized line you can also raise the receiver a
set distance off of the ground, and verify
that the depth reading on the display e -
quals the distance that you raised the re-
ceiver.
4. Once the locating is completed, press the
Power ON/OFF button for 5 seconds to
exit broadcast inductive mode, then press
the ON/OFF button to turn the transmitter
OFF.
