Induction Mode - Locating Utilities - Amprobe UAT-600 Serie Mode D'emploi

1. Turn the Receiver on by pressing the power button for two seconds.
2. Press the " " button repeatedly until Radio is selected.
3. Follow the steps as described in the Receiver Locating section 3.1.
The Left/Right arrows are not active during passive location, such as in Power or Radio modes.
3.4 Induction Mode – Locating Utilities
Induction Mode is particularly useful for identifying the location of multiple buried utilities before digging.
Induction Mode can be also used for tracing individual cables where there is no access to the line to connect
test leads or a clamp. However, this method may not be reliable if adjacent lines are present because the signal
will be also applied to these lines.
Without the test leads or signal clamp connected to the Transmitter, the Transmitter will automatically start to
radiate a signal around it using an internal antenna. These signals will penetrate the ground and couple onto
buried lines. The signal will then travel along the line which can be detected with the Receiver.
With the Induction 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.
Induction Mode – Setting Up the Transmitter
When using Induction Mode, place the Transmitter at least 65 feet (20 m) away from any structure such as
building or a tower to avoid signal interference. Before tracing, take a visual inspection of the area looking for
clues were the buried utility might be present, such as transformers, manholes, street or parking lamps, etc.
The signal will radiate around the Transmitter as well as below it, so it is recommended that when applying a
signal using Induction Mode, a distance of at least 65 feet (20 m) is kept from the Transmitter when pinpointing or
taking depth readings. While locating closer than 65 feet is possible, the operator should be aware that the signal
directly received from the Transmitter may be strong enough to influence the results.
Avoid placing the Transmitter over metallic manhole covers as this will severely reduce the effectiveness of the
Transmitter, and in extreme cases, cause damage to the Transmitter's circuitry.
1. Turn the Transmitter on by pressing the power button for two seconds.
2. Place the Transmitter over the suspected location of the line, positioning it so that it is along the line.
