4. How the Thermometer Measures Body Temperature

The thermometer measures infrared energy radiated from the
skin above of the eyebrow area and the surrounding tissue. This
energy is collected through the lens and converted to a tempera-
ture value.
Temperature readings obtained by scanning above the eyebrow
area will provide the greatest accuracy.
