How to obtain Emissivity?
In the EMS mode, press and hold the Trigger and in the same
time press the Laser/Backlight button twice: once short and second
one longer until the EMS icon on the left side of LCD blinking. At
this time, “
ε
= --” will appear at the upper side of the LCD; IR
temperature value will be in the middle of LCD; and Type K
temperature value is at the lower side of the LCD.
Contact the Type K probe to the object surface and test the
temperature of same point with IR measurement. After both values
are stable, press UP or DOWN button for confirmation. Then,
emissivity of the object will be shown at the upper side of the LCD.
Press MODE button or trigger to enter normal measurement.
Note:
1.
When the IR value is not corresponding to the TK value, or IR
and TK tested the different points, no emissivity will be
obtainable or a wrong emissivity will be obtained.
2.
The temperature of the target should be higher than the
