7. RADIO MODE
The passive Radio Mode employs only the
PL-2000 Receiver and the ambient radio
signals emanating from power lines, radio
stations, and other low frequency radio
communications. These radio signals are
present all over the earth and they often
energize long pipelines, such as water and
gas lines.
1. Press the Frequency Select key (2) until
“Radio” is displayed on the receiver’s
screen.
2. At the Operating Mode key (3), choose
the “Peak” Mode. The Radio Mode only
works with “Peak” Mode.
3. Increase or decrease the Sensitivity (4)
with the up/down arrow keys until the
“signal pyramid” appears as two bars on
the pyramid sides.
NOTE: The DEPTH function is not available
in Radio Mode.
8. SONDE MODE
The Sonde Mode is useful for locating non-
metallic pipelines, like PVC or asbestos/ce-
ment sewer pipes, clay pipes, concrete, etc.,
that do not have a “tracer wire.” A “Sonde” is
a small battery powered transmitter that can
be attached to a sewer “snake,” other ex-
ible rod, or a “PIG,” and pushed, or ushed
through the pipe with a string attached to it.
Check the particular Sonde and PL-2000
Receiver together rst outside of the pipe
on the ground. Conrm that the Receiver
is detecting the Sonde and measuring its
depth correctly.
1. Turn ON the PL-2000 Receiver and
press the Operating Mode key until a
small Sonde appears in the upper left
corner of the display.
2. At the Frequency Selection Key, choose
27 kHz, 8 kHz, or a .5 kHz, depending
upon the frequency transmitted by the
Sonde.
3. Turn ON the Sonde and lay it on its
side. The PL-2000 receiver detects the
Sonde from the side of the Sonde. When
the Sonde moves through the pipe, the
receiver is faced parallel to the pipe (and
the Sonde) and not in the direction of the
pipe (90 degrees from normal operation).
4. A Sonde makes 3 peaks: A large one
directly over it and two “false” peaks, one
off each end of the Sonde.
