METRICA 60290S Mode D'emploi page 11

Thermometer converts the electrical signals into temperature
reading and displays the result on the LCD.
The infrared energy released by the object is directly proportional
to its temperature and to the emission power
This is called emissivity; it is related to the material and gloss
of the object.
The emissivity value ranges from 0.1 to 1.0. As the same with
our product.
The emissivity of most organic material and paint is 0.95.
In the event that there is a problem please set the emissivity
to 0.95.
