Step 10.
After a fault is found and pinpointed, move the 3M™ Earth Contact Frame
about one frame width away from the fault and insert it in the ground with the
green-banded leg towards the fault. Compare the numeric signal level with
the fault signal strength level reference indicated in the lower left box labeled
REF
. If the reading is within 12 dB of the fault signal strength reference, the
operator has found the major fault. If the fault reading does not fall within 12 db
of the fault signal strength reference reading, multiple faults may exist. The
signal level of this secondary fault can be saved by pressing
Fault 1
[SK] or
Fault 2
[SK]. The fault with the highest reading will be the primary fault.
