Electronic Markers & Ems-Id Markers; Enabling/Disabling Marker Types; Locating Ems Markers - 3M Dynatel 2250M Series Operator's Manual

After a fault is found and pinpointed, move the 3M
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 level reference indicated in the lower left box labeled REF. If
the reading is within 12 dB of the reference, the operator has found the major
fault. If the fault reading does not fall within 12 db of the 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.
