Crosses
A cross is located by connecting the clips to the two crossed wires. Connect one clip transmitter to the
faulted wire (Tip or Ring) and the other clip to the cable sheath. The current will flow through the
grounded wire and the sheath.
The signal will be minimal or non-existent on the side of the fault away from the transmitter.
5.2.4
Pair Split
The SR-101 relies on current flow in the pair to be able to receive the signal on the pair. A split pair does
not have a complete circuit so one must be created.

During identification of the split, the technician must identify the two pairs involved in the split and if
the tips or rings are split. The diagram shows a split and a temporary short placed at a point beyond the
fault.
A split location is detected by an increase in signal after the split. Moving the probe back over
the fault location verifies the location.
Signal increase when
passing a high resistance
fault such as a Split.
Confirming the fault
location by moving back
across the fault point.
Minor signal variations on
the cable before and after
any fault is normal. These
are caused by the twist in
the cable.
