2 PCM
+
Operation Manual
Eliminates the need for the operator to perform
‘current spans’ and manual calculations to
determine CP currents along the pipeline that require
connection to the pipeline.
Is designed for the Pipeline Industry with guidance
and support from Gas Industry leaders.
The PCM
+
is one part of the Radiodetection Pipeline
Product range, which also includes the Stray Current
Mapper and Smart Interrupter.
PCM
+
Transmitter
The PCM
+
system’s specialized constant current high-
power transmitter 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 transmitter has three operating modes that enable
both distribution and transmission pipeline systems to be
effectively mapped.
Connecting the PCM
+
is straightforward, and the
transmitter’s current reading LCD and power indicating
LEDs help the operator to choose the best settings for
the specic pipeline application.
For PCM
+
Transmitter operating instructions, please refer
to Section 2.

Receiver
The handheld receiver unit is used to locate the pipeline,
even in heavily congested areas. The receiver provides
the operator with a measurement of depth current
strength and direction of the near DC signal applied by
the system’s transmitter.
The receiver makes the required calculations and
instantaneously displays the results. This provides the
operator with an improved method that accurately
troubleshoots the CP system by pinpointing metallic
contacts and locating areas of coating defects.
For PCM
+
receiver operating instructions, please refer
to Section 3.
