FaultFinding
Connect the A-Frame to the Receiver Accessory
Socket.
Switch the Receiver On and select 8 kHz using the
'f' key.
Using the Peak/Null key, select Peak or Null and
trace the route of the suspect section of cable.
Using the Peak/Null key select Accessory Socket
and push the A-Frame spikes into the ground,
near the earth stake of the transmitter, with the red
spike nearer the ground stake.
The Receiver display will indicate the 'dB' level
with a forward pointing arrow.
Note: Both the meter bargraph and audio are
disabled during FF.
Follow the cable route pushing the A-Frame
spikes into the ground at regular intervals and
check for a forward pointing arrow.
When the backward pointing arrow is displayed
move the A-Frame backwards or forwards, as
indicated by the direction of the arrow, until the
exact point is found where the arrow changes
direction.
Midway between the spikes mark the ground with
a line at 90° to the A-Frame.
