3.5
Locating Mode (Response)
The vLocPro2 receiver has four antennas, and these can be toggled through different configurations (modes)
to provide different responses to the signals radiating from the buried pipes and cables. The modes are:
3.5.1
Peak Response Mode
This uses the two horizontal antennas and provides a “Peak” or maximum
signal response over the center of the radiated signal from the buried line.
The compass line direction indicator shows the direction of the cable
(available in Active modes). The color of the compass changed from clear
to blue when the receiver is in line with the buried line.
This is the most accurate of the locating modes as both antennas are
used to provide a clearly identifiable “Peak”. In the “Peak” mode, a “Peak”
signal indicator helps to clarify the position of the “Peak”. This shows the
last “Peak” located for a few seconds, enabling the user to return to that
position quickly.
3.5.2
Broad Peak Mode
This uses a single horizontal antenna and provides a “Peak” or maximum
signal response over the center of the radiated signal from the buried line.
The compass line direction indicator shows the direction of the cable
(available in Active modes). The color of the compass changed from clear
to blue when the receiver is in line with the buried line.
This is less accurate than the twin horizontal antenna “Peak” mode – but
is useful if the buried line is particularly deep. For pinpointing the line, the
“Peak” mode should be used.
3.5.3
Null Mode
This uses vertical antennas and provides a minimum or “Null” response
over the center of the radiated signal from the buried line. The compass
line direction indicator shows the direction of the cable (available in Active
modes). The color of the compass changed from clear to blue when the
receiver is in line with the buried line.
Some users prefer the null response; it works well in uncongested areas,
but is more prone to inaccuracies due to distortion of the radiated signal
in congested areas.
Left/right indication arrows are also displayed when in “Null” mode. The
arrows indicate the direction to move the receiver to locate the position of
the buried line.
