Passive Location Of Energized Cables And Power Lines; Radio Mode - Passive Location Of Utilities - Amprobe UAT-600 Serie Mode D'emploi

If the reading is off scale (too great or too small), then pressing the "
adjust the sensitivity to bring the meter deflection to 50%.
5. Rotate the Receiver on its axis to obtain the maximum signal. This indicates that the Receiver is directly over
the line and aligned with the direction of the cable. The direction can also be verified by rotating until the
smallest signal is detected – the Receiver is then perpendicular with the cable/pipe.

6. Walk along the path of the cable and trace it by moving the Receiver left to right to find the highest signal.
3.2 Power Mode 50/60 Hz – Passive Location of Energized Cables and Power Lines
Power signals are created by mains power running in the supply cables. These signals are 50 or 60 Hz depending
on the region (for example, Europe has 50 Hz power and the United States has 60 Hz power). This frequency can
be adjusted on the Receiver.
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 very well balanced cable (exactly the same current flowing in live
and neutral) will cancel out and may not create a signal. In practice this is unusual as there are usually enough
imbalances in the cable to create a good detectable signal.
1. Turn the Receiver on by pressing the power button for two seconds.
2. Press " " button repeatedly until the correct frequency is selected. To change frequency between 50 or 60
Hz refer to UAT-600-R Receiver Controls and Display section 2.2.
3. Follow the steps as described in the Receiver Locating section 3.1.
3.3 Radio Mode – Passive Location of Utilities
Radio signals are created by low frequency radio transmitter
and are used for broadcasting and communications. They are
positioned throughout the world. As the frequencies are very
low, the signals tend to penetrate and hug the curvature of the
earth. 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. Tracing of non-metallic pipes and conduits
will be possible after inserting metal fish tape or cable.
