The animation depicts the sequence of events that occur if two six foot (1.8 m) tall people pass through the detector carrying handguns. The first passes through the detector carrying a single weapon at chest height. The second carries weapons at ankle and chest height. The yellow profile on the alarm display shows the relative height of a 5 foot (1.5 m) person with respect to the archway, while the white profile represents a six foot person.

The bar graph display shows the relative size of the signal generated by the detected metal.
