9. Attention

All objects radiate infrared energy, which is based on the
actual surface temperature and surface radiation
coefficient of the object.The product perceives the
infrared energy on the surface of the object and uses the
data to calculate the estimated temperature.many
common objects and materials (such as painted metal,
wood, water, skin and fabric) can radiate energy
effectively, so it is easy to obtain relatively accurate
measurements.for the surface which is easy to radiate
energy (high radiation coefficient), the radiation
coefficient is greater than 90% (0.90).this simplification
does not apply to glossy surfaces or painted metals
because their radiation coefficients are less than 60%
(0.60).these materials are not easy to radiate energy and
are classified as low radiation coefficient materials.In
order to measure the material with lower radiation
coefficient more accurately, it is necessary to correct the
radiation coefficient.adjusting the radiation value usually
enables the product to calculate the actual temperature
more accurately.
