d. After eight seconds, there will be a success
tone / vibration / LED pattern and the
detector will return to Detection Mode. If
the Ground Balance procedure was not
successful, there will be a failure tone /
vibration / LED pattern depending on which
alert responses are enabled.
e. Sweep the Coil back over the metal-free
ground checking for any ground noise or
false detections. Repeat Ground Balance
if required.
NOTE: After switching on the MF5,
when selecting IED or Conventional
Operations for the first time, a Ground
Balance procedure should be completed.
Provided the detector software is not
upgraded, subsequent selections of IED
or Conventional Operations do not require
another Ground Balance.
When the detector is switched off, Ground
Balance profiles for IED and Conventional
Operations are retained.
Completing the Ground Balance procedure

may allow the selection of a higher
sensitivity level due to reductions in
ground noise and false detections.
STEP 3: Test Piece Procedure
NOTE: The MF5 is supplied with a
Test Piece designed to confirm that
the detector is working to correct
specifications. The sensitivity of the
detector should be checked with the
Test Piece when the Sensitivity Knob
is at Level 3 for either IED or
Conventional Operations.
a. Ensure hands and arms are free of metallic
objects (watches, rings, etc.) and that no
other metallic objects are near the Coil.
b. Select sensitivity Level 3 in either IED or
Conventional Operations.

c. Fully slide back the Armrest and rotate
the Test Piece to remove it from its
stowed position.
d. Hold the Test Piece by the end that
contains the metal test-target.
Hold the Test Piece perpendicular to the
bottom of the Coil, lightly touching the
surface of the Coil with the tip of the Test
Piece. Smoothly and slowly move the Test
Piece across the Coil from one side to
the other.
