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 the UAT-600-RE Receiver Controls and Display section 2.2.
3. Follow the steps as described in the Receiver Locating section 3.1.
