Description, Specifications
And Standard Equipment
Description
The RIDGID®SeekTech ST-510 line transmitter is part of
the RIDGID SeekTech cable and pipe locating system. The
ST-510 is used to generate an “active” signal on a metal-
lic underground line so that it may be traced with a com-
patible receiver such as the SeekTech SR-20 or SR-60.
This allows the line’s location to be correctly marked so it
can be exposed for repair or avoided during excavation.
The ST-510 line transmitter can apply an active tracing sig-
nal to a target conductor in three ways:
1. Direct Connect Method – The transmitter’s leads are
connected directly to the target conductor and a suit-
able ground (See page 8) .
2. Inductive Clamp Method (optional accessory) –
The jaws of the inductive clamp encircle the target
conductor; there is no metal-to-metal contact (See
page 9) .
3. Inductive Mode – The transmitter is placed over,
and in-line with, a conductor. Its internal antenna in-
duces a signal onto the target conductor (See page
9) .

Installing Batteries
To install batteries in the ST-510 Line Transmitter, turn
the knob on the battery holder counter clockwise until the
holder is loose. Slide the holder straight back to re-
move from the transmitter. (See Figure 6.)
Figure 6 – Removing Battery Holder
Install eight “D” size batteries into the battery holder as
indicated on the decal on the holder.
Use batteries that are all of the same type
(example – all Alkaline or all NiCd). Do not mix battery
types. Do not mix used and new batteries. Mixing bat-
teries can cause over heating and battery leakage.
Fit the battery holder back into the transmitter case and
slide in. Push slightly on the holder and turn the knob

SeekTech®ST-510 Line Transmitter
clockwise to secure the holder in the case. The bat-
tery holder can be installed in either orientation.
Always remove batteries before shipping unit.
Operation Time
Typical operation time for transmitter with batteries
varies depending on battery type, transmitter settings
(load), backlight use, Battery Saver Mode use, operating
temperature and other factors. When using alkaline
batteries, under average conditions, the batteries will
supply about 12.5 hours of operation. See Estimated
Battery Operating Times Chart for more information.
The ST-510 Line Transmitter also includes an auto shut-
off feature to help prevent batteries from running down if
the unit is left on inadvertently. Batteries used in high-cur-
rent applications may recover and still be usable if allowed
to rest overnight prior to being used again.
Alternate Power Supply
1. Using the transmitter with battery power provides the
highest level of electrical isolation and is the recom-
mended power source. However, the Transmitter can
be used with an external power source, such as a ve-
hicle power jack or a standard outlet. In those cases,
the following isolated adapters are recommended.
• Use only a power supply approved to IEC 61010-
1 or IEC 60950. Output must be isolated, SELV
and Limited-Energy Circuit per IEC 61010-1 or
LPS per IEC 60950, 12-15VDC, 30W minimum.
Output connection is standard barrel plug, 2.1mm
pin, tip positive.
NOTE: Adapters are sold separately.
If used with an adapter, it is very important that the
above-specified adapter be used to insure appropriate
power is supplied to the transmitter. Be sure to read
and keep the adapter instructions. Make sure the
adapter cord has a clear, dry path without any poten-
tial source of damage. Use dry hands when plug-
ging cords in. Do not turn the transmitter on at
this time.
If the transmitter is used with an external
power source, you must make sure that the external

NOTICE
WARNING

power source is fully isolated from ground and power
mains. If the transmitter is not isolated, the transmitter is
not protected from connection to energized (live) power
lines. This could cause electrical shock and damage the
transmitter. Do not use a non-isolated power supply
with the transmitter.
If using the transmitter with a 12V DC adapter from a ve-
hicle power jack while connected to a power line, the
vehicle is connected to the power line. If that power line is
energized (live), the vehicle now is at the line voltage, and
if the vehicle is grounded, could cause electrical shock or
property damage to both the transmitter and vehicle.
Pre-Operation Inspection
WARNING
Before each use, inspect your transmitter and cor-
rect any problems to reduce the risk of serious injury
from electric shock and other causes and prevent
transmitter damage.
1. Make sure that the transmitter is unplugged and in-
spect the cords and plug for damage or modification.
2. Clean any oil, grease or dirt from equipment handles
and controls. This aids inspection.
3. Inspect the transmitter for any broken, worn, missing,
mis-aligned or binding parts or any other condition
which may prevent safe and normal operation.
4. Check that the warning label is present, firmly at-
tached and readable.
5. If any issues are found during the inspection, do not
use the transmitter until it has been properly serviced.
6. Inspect any other equipment being used per its in-
structions to make sure it is in good usable condition.

Set-Up and Operation
WARNING
Always wear eye protection to protect your eyes
against dirt and other foreign objects.
Set up and operate the transmitter and work area
according to these procedures to reduce the risk of
injury from electric shock, and other causes, and
prevent transmitter damage.
1. Check for an appropriate work area as indicated in the
General Safety Section page 2.
2. Inspect the line to have a signal applied to it. The line
must be metal. If the line is not metallic, it will not be
able to be located with this equipment.
When using the transmitter on insulated conductors,
the target conductor should be grounded at each
end. Otherwise, the signal may not be strong enough
to locate.
The transmitter is not designed to provide high volt-
age isolation and protection. Do not use where a
danger of high voltage contact is present.
3. Determine the correct equipment for the application.
Using incorrect equipment for an application can
cause injury or damage the equipment.
• Equipment for other applications can be found by
consulting the Ridge Tool Catalog, online at
www.RIDGID.com or www.RIDGID.eu.
4. Make sure all equipment has been properly inspected.
5. The ST-510 line transmitter can apply an active trac-
ing signal to a conductor in three ways:
• Direct Connect – The transmitter’s leads are con-
nected directly to the target conductor and a suit-
able ground. This method is most commonly used
when the target utility is accessible. Direct con-
nect should not be used for energized (live) con-
ductors.
• Inductive Clamp (optional accessory) – the jaws of
the inductive clamp encircle the target conductor; if
the conductor is insulated, 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 for ex-
ample. (See Page 9)

Ridge Tool Company
8
SeekTech®ST-510 Line Transmitter
• Inductive Mode – The transmitter generates a field,
which in turn induces a current in the target con-
ductor. There is no direct connection between the
transmitter and the target conductor. The trans-
mitter is placed over and inline with the target con-
ductor. The transmitter’s internal antenna induces
a signal onto the target conductor. This method is
most commonly used when the target utility is not
accessible. (See page 9).
Direct Connect Method
1. Confirm that the target conductor is NOT energized
(live). The transmitter is not designed to be con-
nected to energized (live) conductors.
2. Choose ground spike and target conductor connec-
tion locations. The transmitter leads extend up to 48
feet to give flexibility in choosing connection points.
The leads can act as antennas, and the further they
are extended, the more incidental signal they can
send out. The further the leads are extended, the fur-
ther the receiver should be used from the transmitter
to avoid misleading signals from the cable leads. If lo-
cating close to the transmitter, keep the leads as
short as possible with the excess in the transmit-
ter’s side pockets.
Figure 7 – Attaching Lead To Ground Stake
3. Remove the ground spike from the bottom of the
transmitter and insert it into the earth. A good ground
results in a stronger tracing signal. To get a good
ground, insert the ground spike as far as possible into
the earth. Moist earth will give a better ground than
dry earth. Wetting the earth around the ground spike
can improve grounding. This lowers the resistance of
the circuit. Connect either cable lead to the ground
stake. Always connect to the ground first. If the tar-
get conductor has an unknown voltage on it, this
may allow the current to be directed away from the
user. (See Figure 7).
Grounding can also be accomplished by attaching the
cable lead to things like shovel blades or larger rods
sunk into the earth. These can improve grounding by
increasing area/depth in contact with the Earth.
4. Scrape away any dirt, paint, corrosion or other coat-
ings on the target conductor to insure good contact
with the cable lead. Again, this lowers the resistance
of the circuit and results in a stronger tracing signal.
Connect the other cable lead to the target conductor.
(See Figure 8).
Figure 8 – Connecting Cable Lead To Target Conductor.
5. Press the POWER ON/OFF button on the keypad to
turn the transmitter on. As the power comes on, the
transmitter will emit ascending beeps. The transmitter
will pause to measure how much current is flowing
onto the target conductor. The faster the beeping, the
higher the detected current. To turn the beeping off,
press the sound key. (See Figure 4).
The line transmitter is designed to with-
stand up to 240V AC between the two leads. The pro-
tection is NOT intended to be used continuously. If the
transmitter encounters a target conductor voltage higher
than approximately 42 volts (RMS), a red LED next to the
High Voltage Present Indicator will flash and the LCD
screen will display the safety alert symbol and “HV MODE”
(See Figure 9). If this happens, DO NOT TOUCH THE
TRANSMITTER, CORDS OR CONNECTIONS. The tar-
get conductor is energized and there is the risk of electrical
shock. Use high voltage precautions to disconnect.
Figure 9 – High Voltage Indicator
WARNING

Figure 11 – Transmitter In Inductive Clamp Mode
5. Clamp the jaws of the inductive clamp around the tar-
get conductor. Make sure that the jaws of the clamp
are fully closed. (See Figure 12).
Figure 12 – Inductive Clamp Attached to a Conductor
6. Turn the transmitter on and select a frequency for lo-
cating, check the circuit and adjust current. (See
page 11). Be sure that the receiver is set to the same
frequency. The inductive clamp typically works best
with frequencies around 33 kHz.
7. Once locating is complete, turn the transmitter power
OFF before disconnecting the clamp.
Inductive Mode
1. Properly place the transmitter relative to the target
conductor. On the top of the transmitter is an orien-
tation mark. The orientation mark needs to be aligned
with the target conductor.
(See Figure 13) .
Figure 13 – Orientation to the Line – Inductive Mode
Ridge Tool Company 9
SeekTech®ST-510 Line Transmitter
6. Select a frequency, check the circuit and adjust cur-
rent. See pages 10 and 11 for more information.
7. 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 re-
ceiver is picking up the transmitted frequency by
holding it near the transmitter and observing the in-
crease in receiver signal.
8 Once the locating is completed, press the POWER
ON/OFF button on the keypad to turn the transmitter
off. Always turn the unit off before disconnecting
the cable leads to reduce the risk of electrical
shock. Remove the cable lead from the target con-
ductor 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. Store the cables and ground spike for trans-
portation.
Inductive Clamp Method
1. This method requires an inductive clamp that is not
supplied with the transmitter. Read and follow all in-
struction for the use of the inductive clamp.
2. Confirm that the target conductor is NOT energized
(live). The transmitter is not designed to be con-
nected to energized (live) conductors.
3. Confirm that the transmitter is OFF. If needed, press
the POWER ON/OFF button on the keypad to turn
the transmitter off. Never turn the transmitter on before
attaching the inductive clamp.
4. Insert the plug of the inductive clamp into the jack on
the transmitter (above the battery holder). When the
inductive clamp plug is in place, the transmitter will au-
tomatically be in Inductive Clamp mode, the cable
leads will be disabled, and “Clamp” will be displayed
on the screen. (See Figure 11).

2. Press the POWER ON/OFF button on the keypad to
turn the transmitter ON. As the power comes on, the
transmitter will emit ascending beeps. Press the
Inductive Mode Key. The display screen will read “IN-
DUCTIVE MODE”. (See Figure 14). The transmitter
will make a short buzzing sound when shifting into
Inductive Mode, and after that, will make double beeps
during inductive mode operation. If desired turn the
beeping off by pressing the sound key (See Figure 4) .
Figure 14 – Inductive Mode Key
3. Select a frequency as described in this manual. When
using Inductive Mode, higher frequencies tend to get
a better signal at the receiver.
4. Turn on the receiver/locator and follow its instruc-
tions. Make sure to set the receiver to the same fre-
quency as the transmitter.
Figure 15 – In Inductive Mode, Locate At Least 30 Feet
From Transmitter To Insure Tracing Target
Conductor
When the transmitter is in inductive 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 receiver 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 conductor.
This is called “Air Coupling”. Operate the receiver
at least 30 feet from the transmitter to prevent this.
(See Figure 15).
One way to confirm that you are tracing the target
conductor and not the transmitter field is to look for a
strong, stable proximity signal and a valid depth mea-
surement on the receiver. While directly over the en-
ergized line you can also raise the receiver a set
distance off of the ground, and verify that the depth
reading on the display equals the distance that you
raised the receiver.
5. Once the locating is completed, press the inductive
mode key again to exit inductive mode, then press the
POWER ON/OFF button on the keypad to turn the
transmitter OFF.
Selecting A Frequency
Select a frequency for locating by pressing a frequency
key on the keypad (See Figure 16) . The frequency will be
shown in the display. For 262 kHz, press the 33 kHz key
twice. (In European versions, this will set the frequency to
93 kHz.) The frequency selected will show on the display.
Figure 16 – Frequency Display
It is usually best to use the lowest frequency needed to in-
duce a signal on the target conductor. Lower frequencies
usually travel farther. Higher frequencies generally make
it easier to induce a signal on the target conductor but are
more likely to cause signals on adjacent, non-target con-
ductors causing distortion and reducing accuracy.
The default ST-510 frequency settings are for use with a
RIDGID receiver/locator. If using another manufacturer’s
receiver compatible frequencies will need to be loaded.
The ST-510 transmitter has the appropriate frequencies for
a variety of other receiver/locator units available by using
the manufacturer menu in the main menu. For available

When using the frequency keys while set up for a dif-
ferent manufacturers receiver/locator, the lowest fre-
quency is controlled by the top (closest to the readout)
frequency key. The frequency moves higher with
each key further away from the readout. If there are
more than four frequencies, pushing the frequency
key furthest from the readout multiple times will in-
crement the frequency to the next higher frequency.
(See Figure 19.) As always, the frequency selected is
displayed on the readout.

Receiver/Locator
Check The Circuit
Look at the resistance (Ω- ohms), the voltage (V) and
the current (mA) displayed on the screen (See Figure
20) . Display numbers are approximate. Generally the
lower the ohms (total resistance) the more efficiently
current can be added. Lower total resistance indicates an
efficient circuit and requires less voltage to induce a
signal in the line.
Figure 20 –Display Panel
The transmitter will beep faster if the resistance is lower
and slower if the resistance is higher.
Adjust Current
Use the up and down keys to adjust the amount of cur-
rent in milliamps (mA) (Figure 21) .
More current gives a stronger signal. Less current pro-
longs battery life. Signal strength measured by the re-
ceiver is directly proportional to the amount of current on
the line. More current means a stronger signal will be re-
ceived by the receiver.
To prolong battery life and reduce the chance of the sig-
nal “bleeding over” onto adjacent lines, use the minimum
amount of current needed to get a clear reading on the
receiver.
Figure 21 – Current Selection (Up and Down Keys)
There are 7 current levels that the user can choose
from: 5, 25, 50, 100, 200 or 400 mA.

Figure 22 – Current Selected
When a current level is chosen, the transmitter will adjust
the voltage to try and produce the selected current and
lock it in. If the transmitter cannot produce the current se-
lected, it will adjust down to the next level.
The transmitter’s maximum current output depends on
the amount of resistance in the circuit. When the trans-
mitter is putting out the maximum current possible for in-
ternal and external conditions, MAX will be displayed in
place of the current strength number.
Figure 23 – MAX Current
MAX will also appear if the power output of the trans-
mitter is at its allowable limit.
When the current drops below 5 mA, “LO” will appear in-
stead of a number.
Figure 24 – LO Current
If the desired current output cannot be produced, the volt-
age and ohms (resistance) readings can give useful in-
formation. For example, if the transmitter is putting out a
high voltage, the resistance of the circuit is probably
too high. If the voltage is lower (30V max) and the ohms
(resistance) reading is also low, the line transmitter may
be constrained by power restrictions. (See FCC limits in-
formation on page 4.)
If the transmitter is showing low or no
current, the signal may be too low to be detected by
the receiver locator and inadequate for tracing.
Main Menu
To access the main menu, press the menu key (See
Figure 25) . The Up and Down keys can be used to scroll
through the main menu choices (See Figure 26) in either
direction.

Battery Saver Mode
This allows the user to limit the power output of the ST-510
line transmitter to approximately 1 watt in order to prolong
the life of the batteries. In many cases 1 watt of power is
all that is needed. Using the unit with up to 10 watts allows
for more power to be used, but consumes the batteries
much faster. Battery Saver is off by default.
Figure 27 – Battery Saver and Auto-Off Options
Auto Shut Off Adjustment
Check this box to have an automatic shut OFF of the
transmitter. When checked, using the select key, the ST-
510 will automatically shutdown to help conserve batter-
ies. Shutdown time using this feature varies with current
draw. The approximate values are:
8 hrs 25mA output or less
4 hrs 50-100mA
2 hrs 200-400mA
1hr >400mA
This feature prevents the batteries from running down if
the unit is inadvertently left on. Auto Shutoff is on by de-
fault.
(See Figure 27).

Auto Back Light
The SeekTech is equipped with an automatic LCD back-
light. Whenever a key is pressed, the backlight is acti-
vated to aid viewing for 80 seconds.
Adjusting the LCD Screen Contrast
LCD contrast is set at the factory and should not normally
require adjustment. Optimal contrast is set when the
background remains white, while the black pixels are set
to be as dark as possible.The LCD can be adjusted to
completely white or completely black, which will affect
readability.
LCD contrast may change with extremes in tempera-
ture. When the screen is exposed to high heat from direct
sunlight it may darken. It is recommended that the screen
be shaded if it is to be exposed to excessive sunlight. Use
the shoulder strap to cover the screen if needed.
If the display appears too dark or too light when it is on, it
is likely that the LCD contrast has become misadjusted.
First try powering the unit OFF and then back ON. If the
problem persists adjust the LCD contrast darker or lighter
as needed.
To adjust the LCD Contrast:
1. Press and hold down the select key.
2. Simultaneously press the up arrow key to lighten
the display or press the down arrow key to darken the
display.
