9.1 Emissivity Description

The emissivity of the product can be adjusted from 0.01 to 1.00 with the
default value of 0.95. Many common objects and materials (such as timber,
water, skin and textile fabric) can reflect the heat energy effectively. So it is
easy to obtain relatively correct measurement value. The emissivity is usually
set as 0.95 when the coarse objects that are easy to give out energy. For
semi-matte objects that give out less energy, the emissivity is usually about
0.85 and the emissivity of semi-gloss objects is 0.6. The shiny objects are
divided into materials with low radiation coefficient. The emissivity is usually
set as 0.3 at the time of measurement. Correct setting of the value of
emissivity is very important for you to carry out the most correct temperature
measurement. The surface emissivity will produce giant impact on surface
temperature measured by the product. Understanding the surface emissivity
will enable you to obtain correct temperature measurement result.

9.2. Emissivity setting

The product is provided with four types of object measurement modes:
Coarse object (0.95)
Semi-matte object (0.85)
Semi-shiny object (0.60)
Shiny object (0.30)
According to the characteristics of the measured objects, users may set the
emissivity value through the "self-define" option (please refer to the table of
"emissivity of common materials").
The operating step is as the following:
Emissivity
Matt (e=0.95)
Semi-matt (e=0.85)
Semi-glossy (e=0.60)
Glossy (e=0.30)
