FAQ
What will be if to turn on the leakage not to measure a loop by the
fi
lter?
If it is the loop
fi
rst measurement the device will not make the fault searching because it has
nothing to compare result. If you have already measured a loop by the
fi
lter the device has
remembered this value and has accepted it as a cable length. It will compare this value with the
cable core resistance up to the place of fault. If you make measurements on the same loop then
it is not necessary to measure loop again. You can to start searching several times.
But if you have measured other loop by the
fi
lter before fault searching, and it differs from a
faulted loop then you receive erroneous result of fault searching.
What will be, if wires A and B are mixed, and the bad wire is connected to A?
On the screen you will see “and” near to distance “X”. Under the scheme it is required, that
the cable core B is faulted («
Хв
»). If it is shown «
Ха
», it does not in
fl
uence the result, but we
recommend changing places of a wire A and B – else the measurement is made not only through
a faulty cable core, and initially through a good cable core that can lead to an additional error.
We were selecting a working wire from the List to search an insulation fault location or open-
cable. Is there the difference from which end to connect the cable?
If you were selecting a single-section cable – you can connect to cable from both end. For
multi-section cable – if we connect the 1
st
section from back end it will becomes the last
section; and the last section – becomes a 1
st
. For multi-section cable we are recommended to
put into List the both recording (for both cables end).
