6. Continue moving forward. The 2-digit Fault Signal Level reading will increase as the fault is neared. When
you cross the place of the fault, the Compass Fault Detection will change a direction and the 2-digit Fault
Signal level will start decreasing as you go away from the fault. Maximum reading will be just before and
just after the fault.
7. Carefully place the A-Frame before and after the fault to pinpoint it. Repeating this in a line perpendicular
to the direction of the cable will pinpoint the fault laterally.
If it is suspected that there is just one fault, insert the A-frame approximately 3 ft (1 m) from the ground
stake. Note the two digit number - this is approximately the maximum reading that will be measured
over the fault.
