4 Using the vLoc3-Pro
4.2.1 Detecting Power Signals
1. Switch on the vLoc3-Pro receiver and select Power mode using the “f” button. Notice that the antenna mode indicator will
be showing “Peak” or “Omni peak” as these are the only options in the passive modes.

2. Hold the vLoc3-Pro vertically and away from likely positions of cables or pipes.
3. Adjust the sensitivity using the “+ “ and “-“ buttons so that the bar graph reading is just starting to show some movement.
Note that the compass feature is not available for the Power or Radio modes.
NOTE
Note that there will be no sound from the speaker until the meter reading is above approximately 10%
of full scale.
4. Keeping the vLoc3-Pro vertical, walk across the area to be checked keeping the orientation so that the blade is in line with
the direction of walking (See diagram above). If using the Onmi Peak mode the orientation of the locator is not important.
5. Continue in a grid across the area.
6. If at any time, the meter reading starts to increase, carefully move the locator side to side to detect the maximum signal.
Use the peak level indicator to help conrm the correct position.
