Installing the metal
detector
When installing a short frame system attention must be paid to the metal free area
requirements as set out in the Search head metal-free area, page 100.
Metal free area long frame systems
• There shall be no fixed metal closer to the detector aperture than 1.5 times the aperture
size as measured from the centre line of the detector case depth.
• There should be no moving metal closer to the detector aperture than 3.0 times the
aperture size as measured from the centre line of the detector case depth.
• The metal-free area is symmetrical about each side of the detector.
• The metal-free area may be reduced, but at the possible expense of sensitivity.
