Power Filters
RD7100PL and PLG locators allows operators to take advantage of the harmonic signals
found on power networks. Once in Power Mode, press the
key to switch out of
Radiodetection’s sensitive Power Mode and scroll through five individual Power Filters.
This enables operators to establish if a single large power signal comes from one source
or from the presence of multiple cables. The different harmonic characteristics of the
detected lines can then be used to trace and mark their route.
Additionally the use of an individual harmonic can allow you to locate power lines in
situations where the total signal would otherwise be too large.
Locate Modes
Dependent on the model selected, the RD7100 offers a choice of up to 4 locate modes,
each of which is designed for specific uses, depending on what task is being carried out.
To scroll between locate modes, press the
key.
PEAK:
For accurate locating, the peak bargraph provides a visual readout of the
signal strength. The peak signal is found directly over the buried utility.
PEAK+:
Choose to combine the accuracy of the Peak bargraph with Null arrows,
which can indicate the presence of distortion, or with proportional Guidance
arrows for rapid line tracing – switch between them by holding the
key.
GUIDANCE:
Proportional arrows and a ballistic ‘needle’ combine with audio
left / right indication for rapidly tracing the general path of a buried utility.
NULL:
Provides a quick left / right indication of the path of a utility. As Null is
susceptible to interference, it is best used in areas where no other utilities
are present.
Depth, current and compass readouts
WARNING! Never use the depth measurement readout as a guide for
mechanical or other digging activity. Always follow safe digging guidelines.
The RD7100 locator can measure and display the utility depth, locate signal current and
the relative orientation of the cable or pipe to the locator. This helps you to make sure that
you are following the right cable or pipe, especially when other utilities are present.
The RD7100 locator features TruDepth
™
, a feature that helps you to ensure the accuracy
of your locates. The depth and current are automatically removed from the display when
the locator is at an angle of more than 7.5° from the path of the cable or pipe being
located, or when the locator determines that signal conditions are too poor for reliable
measurements.
