Speedrite FAULT FINDER Manual De Uso página 3

Earth wire return
The current readings are low in several places, indicating there is no fault on the fence
line.
The current readings are particularly high indicating there is a fault somewhere on the
fence line. The significant reduction in current between readings helps to identify the
location of the fault. In this case, the two wires with abnormally high readings may be
connecting with each other, causing a fault. The bottom wire has consistently low
current readings indicating that this wire is OK.
Note:
Current readings taken within 1 m (3') of an energizer may not be completely
accurate due to the magnetic field surrounding the energizer.
To find a fault in the fence line:
1 Start close to where the energizer lead-out wire connects to the fence.
2 Press to turn on the handset.
3 Insert the fence wire into the Fault finder slot, ensuring that the fence wire
touches the Fault finder contact. Note the current reading (in amperes) in large
numbers.
4 Travelling in the direction of the current flow, work your way along the fence
line taking readings at regular intervals and at all junction points. At a junction,
follow the branch that indicates an abnormal current reading. Each time you
take a reading, compare it with the previous reading (this displays briefly in the
top, right-hand corner of the screen each time the handset is turned on).
5 A significant reduction in current between one point and the next indicates the
presence of a fault between these two points.
6 Move back in the direction of the previous reading until the fault is located.
Notes:
-
Higher than normal current readings indicate short circuit faults. This could be
caused by vegetation touching the fence line, a broken insulator etc. Lower than
normal current readings with the same voltage usually indicates a poor
connection or a broken wire.
-
On an earth-wire-return fence, readings taken on the earth wire may not indicate
the correct current direction.
