AIR TESTING
$
Let’s Warm Up
Air testing is a good way to become familiar with the detector by testing a range of
metal objects. This exercise is a simple lesson on how the detector tells metal objects.
Gather a collection of different metal objects, e.g. various coins, gold and silver
jewelry, a nail, pull-tab, brass button and aluminium foil.
Take the detector outdoors, away from known electromagnetic fields or metal
objects. Place the search coil on a flat non-metallic surface. Select DICS mode and
maximize the scale. Lay objects in a line, sufficiently spaced apart to allow the coil to
pass between the objects. Pass the coil across the objects one at a time, and observe
the LCD and the sounds of the detector as it detects each object.
Reduce the DISC bar graph segments to middle position and wave low conductive
metal in front of coil. Record the result of your air testing.
Note:
Never test the detector on a floor inside a building. Most buildings have metal of
some kind in the floor, which might interfere with the objects you’re testing or mask
the signal completely.
