Signal Current Measurement (MXL2 Locator only)
MXL2 Locator only:
Signal Current Measurement is a feature by which it is
possible to measure the TRUE strength of the Generator/
Transmitter signal on a buried metal pipe or cable
irrespective of its depth. This is a useful aid for the
correct identification of specific pipes and cables and
may also help to determine the layout and condition of
a pipe or cable network.
When the Generator/ Transmitter has been connected to
a particular 'target' service, the Locator may not always
show the strongest response over that service. If the
target pipe or cable happens to be much deeper than
other services, which have picked up some of the
Generator/ Transmitter signal, these other services
may show similar responses. However, the Signal Current
reading will invariably be highest on the target pipe or
cable therefore aiding correct identification.
