Power Mode and Radio Mode
Power Mode
Passive Location of Energized Cables and Power Lines
Power signals are created by mains power
running in the supply cables. When electrical
power is distributed throughout the network,
some of the power finds its way back to the
power station via the ground. These stray
currents can jump onto pipes and cables and
also create power signals.
There must be enough electrical current
flowing to create a detectable signal. For
instance, a live cable that is not in use may not
radiate a detectable signal. A cable with exactly
the same current flowing in live and neutral
will cancel out and will not create a signal;
however, there are usually enough imbalances
in the cable to create a detectable signal.
Radio Mode
Passive Location of Utilities
Radio signals are created by low frequency
radio transmitter and are used for broadcasting
and communications. When the signals cross
a long conductor such as a pipe or cable, the
signals are re-radiated. It is these re-radiated
signals that can be detected by Radio Mode.
Locating radio signals is very similar to
detecting power signals as they are both
passive. With the Radio Mode method, you will
detect metallic utilities, such as pipes, as well as
energized and de-energized cables.
Note: The arrows are not active during passive location, such as in Power or Radio modes.
1. Turn the Receiver on by pressing the
power button for two seconds.
2. Press repeatedly until the correct
frequency is selected. Frequency can
be adjusted to 50 or 60 Hz in the Receiver
Settings Menu (for US, select 60 Hz).
3. Follow the steps as described in
"Locating with the Receiver"
1. Turn the Receiver on by pressing the
power button for two seconds.
2. Press "Hz" repeatedly until Radio is
selected.
3. Follow the steps as described in
"Locating with the Receiver"
