8 Using the Accessories
Remove the plastic spike covers from the A-frame. Walk along the route of the line placing the spikes of the A-frame in the
ground (with the green leg pointing away from the transmitter connection point) every two or three paces.
If starting near the transmitter, the arrow on the display will point away from the ground point. As the distance from the
transmitter increases, the dB reading will reduce and eventually the arrow will fluctuate or disappear altogether. This is because
the fault location is further along the line. Use the left/right arrows to ensure the A-frame is positioned over the line and continue
placing the A-frame in the ground every two or three paces. If necessary, use long presses of the “M” pushbutton to enter the
locate screen allowing the user to confirm the position of the target line. Use long press of the “M” pushbutton to scroll through
the screens to re-enter the A-frame mode.

(Note that the A-frame is not shown connected to the receiver so as to simplify the diagram).
Eventually, the A-frame will detect the fault signal and the “Fault Find” arrow will point forward. Continue moving forward, it may
be worth reducing the distance between measurements points as the fault is neared. The dB reading will increase as the fault is
neared. Maximum reading will be just before and just after the fault. When over the fault, the dB reading will drop and the arrow
will flip backward indicating that the position of the fault has been passed.
Carefully place the A-frame before and after the fault to pinpoint the position. Repeating this across the line direction will pinpoint
the fault laterally. The fault will be at the point where the lateral fault is identified.
WARNING
Always disconnect or isolate target/faulty/suspected cables before connecting the transmitter to it.
Never attach the transmitter to live cables.
TIP
If it is suspected that there is just one fault, insert the A-frame approximately one meter from the earth
stake. Note the dB reading - this is approximately the maximum dB reading that will be measured over
the fault.
