The Head menu options available are as follows:
Type
The 'Conveyor' option should be selected for the IQ3X search head.
Coil Gap
The coil gap required can be found on the serial number plate located within the control box of
the detector head. It is set at 0.6 times the smallest aperture dimension, which is generally the
aperture height.
Band
Frequency bands are used to prevent crosstalk between adjacent metal detectors that are
operating on the same frequency.
The options are OFF, or 1 through 10. If OFF is selected then all 70 frequencies, 31 through 937, will
be available for use for all products, making frequency selection and subsequent Learns a
manual process.
If a band number is selected then the 7 frequencies available in the band are used by the metal
detector when selecting the optimum inspection frequency for any product.
