Preface
About this guide
CAUTION: This guide provides basic operating instructions for the PCMx receiver
and transmitters. It also contains important safety information and guidelines
and as such should be read in its entirety before attempting to operate the PCMx
receiver and transmitters.
This guide is intended as a quick reference guide only. For detailed instructions,
including the use of accessories, help with eCert
™
, CALSafe
™
, survey measurements
and usage-logging please refer to the PCMx operation and PCM Manager manuals.
With the magnetometer foot removed the PCMx is automatically congured as an
RD8100 PDLG cable and pipe locator. Additional instructions on its use as a cable and
pipe locator can be found in the RD8100 operation manual. All manuals are available
for download from www.radiodetection.com.
Certicates of conformity for the PCMx and Tx transmitter ranges can be found at
www.radiodetection.com.
WARNING! Direct connection to live conductors is POTENTIALLY LETHAL.
Direct connections to live conductors should be attempted by fully qualied
personnel only using the relevant products that allow connections to energized lines.
WARNING! The transmitter is capable of outputting potentially lethal
voltages. Take care when applying signals to any pipe or cable and be sure to
notify other technicians who may be working on the line.
WARNING! Reduce audio level before using headphones to avoid damaging
your hearing.
WARNING! This equipment is NOT approved for use in areas where
hazardous gases may be present.
WARNING! The PCMx receiver will detect most buried conductors but there
are some objects that do not radiate any detectable signal. The PCMx, or any
other electromagnetic receiver, cannot detect these objects so proceed with
caution. There are also some live cables which the PCMx will not be able to
detect in Power mode. The PCMx does not indicate whether a signal is from a
single cable or from several in close proximity.
WARNING! Batteries can get hot after prolonged use at full output power.
Take care while replacing or handling batteries.
WARNING! The depth accuracy is ± 5% or better under standard earth
conditions and with undistorted elds. If you intend to excavate a located pipe,
it is imperative that due care is taken appropriate to the danger of personal injury
and damage to infrastructure. It is recommended that depth measurement is
repeated throughout an excavation.

eCert and Self-Test
The PCMx receiver is safety equipment which should be regularly checked to
ensure its correct operation.
eCert provides a thorough test of the PCMx locating circuitry including the
magnetometer foot and supplies a Radiodetection Calibration Certicate when a
positive test result is obtained.
To run an eCert, the magnetometer foot must be on and the receiver should be
connected to an internet-enabled PC on which the PCM Manager PC software is
installed. NOTE! Testing without the foot result in a “FAIL”.
Refer to the PCM Manager manual for further details. Additional purchase may be
required.
PCMx receivers incorporate an Enhanced Self-Test feature. In addition to the
typical checks for display and power functions, the PCMx applies test signals to its
locating circuitry during a Self-Test to check accuracy and performance.
We recommend that a self-test is run at least weekly, or before each use.

The Tx-150PCM and the Tx-25PCM
are constant current transmitters which
transmit a 4Hz mapping frequency
suitable for pipeline surveys.
The Tx-150PCM (150W) allows for long
range signal detection of up to 30km
(20 miles). Signicantly fewer pipeline
connection points are needed thereby
reducing the time required to evaluate a
section of pipeline.
The Tx-25PCM (25W) has internal Li-ion
batteries that allow it to operate in the
eld independently of external power
sources.

Indication and warning lights
LCD Display: Displays the 4Hz or 8kHz
signal current that is being delivered
onto the pipe. On startup it conrms the
AC frequency setting and associated
location frequencies. The Tx-25PCM also
displays the battery level on startup.
Output
Voltage Level: Indicates the output
voltage levels. If no LED is lit the output
voltage is below 20V. Do not use
excessive voltage or current, as this may
result in high current density through
small holidays and coating defects.
The may cause minor corrosion if the
transmitter is left on for very long periods.
Voltage Limit: LED on.
Transmitter has reached its 100V output
voltage limit – resistance of the pipe or
ground connection is too high. Check all
connections to correct this problem.
NOTE: If the pipeline being surveyed
has coating that is known to be in good
condition, it is probable that the voltage
warning LED’s will illuminate as the
current is increased.
Undesirable voltage on output:
LED ashes. This indicates a high
voltage, such as mains, has been
detected on the output. The unit will
not operate until the cause of the high
voltage has been removed and the
transmitter has been reset by switching
it off, and on again.
Power Limit: System cannot
supply power required to
support transmission at the selected
current. Switch to a lower current setting
until the OK LED illuminates GREEN.
Allow a few seconds to settle between
selections.

PCMx transmitter
signal connection
WARNING! Appropriate safety
procedures must be followed before
removing pipeline CP connection from
the rectier. Before handling connection
leads switch both the rectier and PCMx
transmitter OFF.
Connection to a rectier
A rectier station is an ideal place to
connect the output of a PCMx transmitter
as it provides connections to both pipe
and an anode bed for a suitable ground.
The rectier can also be used to power
transmitter using the mains supply. The
Tx-150PCM can also be powered from
the rectier output.
1. Disconnect both pipe and anode
cables from the rectier.
2. Ensure the transmitter is turned off.
3. Connect the White signal output lead
to the pipe cable.
4. Connect the Green signal output lead
to the anode cable.
When connection to a
rectier is not possible
Connection of a PCMx transmitter can be
made to a suitable test point or directly
to the pipeline itself. Connect the White
output cable to the connection that is
connected directly to the pipeline and
connect the Green output lead to either
a sacricial anode or use a suitable earth
stake.
If using a sacricial anode, make sure
that it is not directly connected to the
pipeline. When using an earth stake,
position the stake 45m / 150 feet away
from the pipe. To achieve a suitable
earth, it may be necessary to use more
than one earth stake linked together.
When connecting to an electrical
isolation joint, you may connect the
White lead to one side of the joint and
the Green output lead to the opposite
side of the pipe section as this can often
provide a suitable ground connection.

is indicated by a rising bar graph and
an increase in tone when volume is
switched on.
Pinpointing denes the exact position
and direction of a pipeline after its
position is approximately known.
Pinpointing is important as the depth
and current readings are affected by
misalignment errors.
1. Adjust the receiver sensitivity to
approximately 50% by pressing
the
and
keys. This enables
changes in the bar graph to be more
readily seen.
2. Hold the PCMx upright and near to
the ground.
3. Move it slowly from side to side
and dene the point of maximum
response by looking at the bar graph.
The guide arrows should be at
minimum length.
4. To align the PCMx with the pipeline,
rotate the receiver until the compass
is in the 6 O’clock position.
The PCMx receiver features TruDepth
™
, a
feature that helps to ensure the accuracy
of locate or survey measurements. When
the receiver is not aligned correctly with
the pipe direction, the depth and current
measurements are automatically removed
from the display. The measurements
will also be removed when the receiver
determines that signal conditions are too
poor for reliable results.
Having pinpointed the pipe, the PCMx will
display the depth of the pipe, (measured to
the center of the pipe), and the current of
the locate signal. It is now possible, using
the guide arrows, to follow the pipeline.

the GPS lock symbol will display on
the screen. An indicator of the number
of satellites in view is also given.
Conducting an ACCA survey
An Alternating Current, Current
Attenuation, (ACCA) survey measures the
attenuation of the transmitted 4Hz signal
to establish the pattern of current loss.
The results can be used to; establish the
condition of the pipeline coating, locate
faults, or nd shorts caused by contact
with other metal objects.
Having used the pinpointing method
above to ensure you are directly above
the correct pipeline, it is now possible to
take measurements of the 4Hz signal.
Procedure:
1. Use the peak response reading and
compass direction to ensure you are
directly above the pipeline.
2. Sit the receiver on the ground,
keeping it upright and very still.
3. Press and hold the
key for
approximately one second. Upon
release a live 4Hz reading is
displayed on the bottom right of the
screen. It is normal for this reading
to uctuate within a couple of mA.
However, a widely uctuating reading
To overwrite a saved result, select the
result log and press
. Once a new
measurement is taken, press the
key
to overwrite the selected reading. The
log number that was overwritten will be
displayed and the receiver will revert to
storing new measurements at the end of
the current records.
Conducting an ACVG survey
An Alternating Current Voltage Gradient,
(ACVG), survey measures the leakage
current in the vicinity of the pipeline
to assess the coating condition, and
pinpoint coating defects. An advantage
of this survey method is that it can be
done on a route parallel to the pipe. For
example, it may be done on a pavement
or grass verge parallel to a pipe running
below a road surface. It requires the use
of an A-Frame in addition to the PCMx
receiver and transmitter.
Procedure:
1. Connect the transmitter to the pipeline
and ground using the procedure
described previously.
2. Set the PCMx transmitter to either
ELCD or LFCD mode.
3. Connect the A-frame to the PCMx
receiver via the accessory socket,
and turn on the receiver.
may indicate interference and it may
be better to move along the pipeline
to take the measurement.
4. The reading can be stored by pressing
the
or rejected by pressing the
key. The PCMx can store up to 10,000
readings and the log number of the
stored reading will be shown on the
display.
5. Continue taking readings in this way
along the length of the pipeline you
wish to survey
6. For best results, readings should be
taken at intervals of equal distance.
NOTE: If Bluetooth is switched on, the
PCMx receiver will automatically attempt
to send the reading via Bluetooth to
a paired device. If the PCMx has not
been paired, a BT error code will be
displayed. If it is intended to only save
the reading internally within the PCMx
receiver, switch the BT-PC setting in the
DATA menu to OFF.
Temporary measurements
In some situations, it can be difcult to view
the display when taking a measurement.
A temporary measurement can be taken
for review before committing the record
to memory. Take the measurement as
detailed above, but instead of pressing
the save or delete key, press the antenna
key
The measurement will be held
on screen for review. To save the
measurement, press
.
Review and Overwrite
Measurement Logs
Saved readings within the PCMx can be
reviewed or overwritten. To view a saved
result, press
to enter the system menu
and select VIEW. The last saved result will
be displayed. To view other logs, use the
or
keys to step through.
4. The PCMx will automatically choose
ACVG mode and an A-frame symbol
will be displayed.
5. Choose an appropriate starting point
for your survey. If a suspected fault
location has been identied from a
previous ACCA survey, begin the
survey approximately 60 feet, (20
meters) from the suspected fault.
6. Place the A-frame spikes in the
ground above, or parallel with,
the pipe. Position the green spike
forwards and the red spike towards
the transmitter connection point.
7. If no fault is apparent, the arrows
will icker on and off and the dB
readings will be erratic. When a fault
is present, the Fault Find, (FF) arrows
will display the fault direction and the
dB readings will be stable. The dB
reading will increase as the A-Frame
is positioned closer to the fault.
8. Follow the pipeline pushing the
A-Frame spikes into the ground at
regular intervals and checking for
FF arrows.
9. Move in the direction of the arrows.
Find the point at which the arrows
change direction. If the A-frame has
been positioned directly above the
pipe, the fault location will be directly
below the A-Frame at this point.
10. If the measurements have been taken
to the side of the pipe line, rotate the
A-Frame 90° so that the green spike
points towards the pipeline. Move
back and forth across the pipeline to
locate the fault in this direction, the
intersection point will be directly over
the fault.

ENGLISH
Conducting survey types
simultaneously
The PCMx allows users to conduct
both an ACCA and an ACVG survey
simultaneously. By collecting the data in
one pass of the pipeline, rather that two,
survey time can be reduced signicantly.
Procedure:
1. Connect the transmitter to the pipeline
and ground using the procedure

指示灯和警告灯
LCD 显示屏：显示输送到管道上的 4Hz
或 8kHz 信号电流。在启动时，它确认
了 AC 频率设置和相关的位置频率。Tx-
25PCM 还会在启动时显示电池电量。
输出电压
水平：表示输出电压水平。如果 LED 灯
没有亮起，这意味着输出电压低于 20V。
请勿使用过高的输出电压或输出电流，因
为这样可能在管道泄漏处或涂层破损点产
生很高的电流密度。长时间施加信号会造
成轻度腐蚀。
电压限值：LED 灯亮。发射机
已到达 100V 输出电压限值——管道电阻
或大地电阻过高。检查所有连接以纠正此
问题。
注：如果被测管道具有已知处于良好状态的
涂层，则电流警告 LED 可能随着电流增加
而发亮。
输出电压不合要求：
LED 灯闪烁。这表示在输出上检测到高电
压（例如电源）。在高电压的原因被消除
并且发射机已经通过关闭并重新打开后被
复位之前，设备将不会运作。
功率超限：系统无法按选定电
流输出提供发射电能。切换到
较低的电流设置，直到 OK LED 灯变为绿
灯。电流调整后需几秒钟才会稳定。
Tx 温度过高：如果温度超过建议的
限制，指示灯将亮起。发射机会自
动关机。等发射机冷却后才能再开机。

耗的模式。结果可用于：建立管道涂层的
状况、定位故障或找到与其他金属物体接
触所引起的短路。
使用上面的精确定位方法确保您位于正确
的管道上方，现在可以测量 4Hz 信号。
程序：
1. 使用峰值响应读数和罗盘方向，以确
保您直接位于管道上方。
2. 将接收机放在地面上，保持直立且一
动不动。
3. 按住
键约一秒钟。释放后，屏幕右
下方将显示 4Hz 的实时读数。这个读
数在几 mA 内出现波动是正常的。然
而，大幅波动的读数可能表明干扰，
沿着管道进行探测可能会更好。
4. 按
键可以存储读数，或者可按
键拒绝。PCMx 可以存储多达 10,000
个读数，而显示屏上将显示已存储读
数的记录编号。
5. 沿着您想要测量的管道长度继续读取
读数
6. 为获得最佳结果，应按一定的间隔进
行测量。
进行 ACVG 探测
交流电压梯度（ACVG）探测将测量管道
附近的泄漏电流，以评估涂层状况，并确
定涂层缺陷。这种探测方法的优点是可以
在与管道平行的路径上完成。例如，它可
以在平行于在路面下方行进的管道的路面
或草地边缘上进行。除 PCMx 接收机和发
射机外，它还需要使用 A 字架。
程序：
1. 使用先前描述的方法，将发射机连接
到管道和地面。
2. 将 PCMx 发射机设置为 ELCD 或
LFCD 模式。
3. 通过附件插口将 A 字架连接到 PCMx
接收机，并打开接收机。
4. PCMx 将自动选择 ACVG 模式，并显
示 A 字架符号。
5. 为您的探测选择适当的起点。如果从
先前的 ACCA 探测中识别出疑似故障
位置，则从可疑故障开始大约 60 尺
（20 米）处开始测量。
6. 将 A 字架的脚钉放在地面上或与管道
平行。将绿色脚钉向前放置，红色脚
钉朝向发射机连接点。
7. 没有故障时，箭头将前后闪烁不定，
而且 dB 读数将不稳定。当存在故障
时，故障查找（FF）箭头将显示故障
方向，而且 dB 读数将稳定。当 A 字
架接近故障点时，dB 值将会增大。
注：如果已打开蓝牙，PCMx 接收机将自
动尝试通过蓝牙将读数发送到已配对的设备
上。如果尚未配对 PCMx，将显示 BT 错误
代码。如果仅打算在 PCMx 接收机内部保存
读数，请将 DATA菜单中的 BT-PC 设置切
换到 OFF。
临时测量
在某些情况下，进行测量时可能难以查看
显示。在将记录提交到记忆之前，可以进
行临时测量以进行审查。进行上述测量，
但不按下保存或删除键，而是按下天线键
。测量将保留在屏幕上以供查看。要保
存测量，请按
。
查看和覆盖测量日志
PCMx 中保存的读数可以被检查或覆盖。
要查看保存的结果，请按
进入系统菜
单，然后选择 VIEW。最后保存的结果将
被显示。要查看其他记录，请使用
或
键逐步执行。
要覆盖保存的结果，请选择结果记录，然
后按
。一旦进行新的测量，按 键以
覆盖所选读数。该被覆盖的记录编号将被
显示，并且该接收机将恢复到在当前记录
结束时存储新测量。
8. 沿着管道以定期的间隔将 A 字架脚钉
插入地面并检查 FF 箭头。
9. 沿箭头方向移动。找到箭头改变方向
的点。如果 A 字架位于管道的正上
方，则故障点将直接在 A 字架下方。
10. 如果测量已经到达管道侧面，请将 A
字架旋转90°，使得绿色脚钉指向管
道。在管道上来回移动，并以这个方
向定位故障，中心点就在故障点的正
上方。

同时进行探测类型
PCMx 允许用户同时进行 ACCA 和 ACVG
探测。通过在管道的一次通过中收集数
据，而不是两次，这将可明显减少探测时
间。
程序：
1. 使用先前描述的方法，将发射机连接
到管道和地面。
2. 将 PCMx 发射机设置为 ELCD 或
LFCD 模式。
3. 通过附件插口将 A 字架连接到 PCMx
接收机，并打开接收机。
4. PCMx 将自动选择 ACVG 模式，并显
示 A 字架符号。
5. 通过重复按
键，使接收机与发射机
的模式相匹配。
6. 按照上面给出的程序进行 ACVG 探
测。显示屏将显示定位信息（峰值+模
式）和 FF 信息。
7. 要采取 4Hz 的电流读数，按照上面给
出的步骤 2 到 6 进行 ACCA 探测。
