4 Locating
Page 13 of 33
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 vScan vertical, walk across the area to be checked.
5.
Continue in a grid across the area.
6.
If at any time, the meter reading starts to increase, carefully move the locator forward and back to detect
the maximum signal. Use the peak level indicator to help confirm the correct position.
7.
Rotate the vScan on its axis to obtain the maximum signal. The vScan is now directly over the line and with
the blade across the line.
8.
The direction can also be found by rotating until the smallest signal is detected. The blade is then in line
with the cable/pipe.
9.
Continue to locate the position of the line at regular intervals until its course is known through the target
area.
NOTE
In busy environments it is not always possible to look at the meter and take note
of traffic movements around you. In these situations it is best to locate the
position of the line using mainly sound rather than meter response. In very noisy
situations even the speaker sound may be drowned out. In this instance,
unscrew the speaker earphone and place it close to the ear to hear the sound
from the detected line.
