As shown in the figure, press “ / MENU” key to enter the main menu
and select “ ”(emissivity) option and press “ ” key to enter
the emissivity list.
Press “ ” and “ ” keys in navigation key to select the
emissivity. Then press “ SELECT/ENTER” key to determine selection
of the emissivity. Press “ ” key again to return.

4.1. 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.
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”).
