3.8 How to Locate a Fault
When you test a defective cable, always obey by the following basic rules:
(1) Observe the safety precautions given in section 0 without fail.
(2) De-energise the cable to be tested, whenever possible. When you
take measurements on a live line, its voltage must not exceed 250
V AC/DC. In this case do not open the accumulator compartment
and do not remove the cap of the serial interface.
(3) The
Digiflex Com is able to measure the length of the cable and the
distance to a point of fault. It is not able, however, to find out the route
of the cable between the point of measurement and the location of the
fault.
(4) The precision of the distance reading by the
Digiflex Com can only be
as good as the precision with which you know the pulse propagation
velocity of the connected cable. In a wet cable the pulse travel time is
increased, so the distance display is too long when the same settings
are used as for a dry cable.

Digiflex Com allows various type of faults to be detected. These are a
few examples:
