2. The temperature of the measuring object should
be above the ambient temperature.
Normally, a temperature of 100 ° C is suitable to
measure an emission factor with a higher
accuracy.
If the difference between the infrared value (in
the middle of the LCD display) and the TK
measurement value (in the display below) is too
large, after measurement of the emission factor,
the measured emission factor will be inaccurate.
In this case, the measurement of the emissivity
has to be repeated.
After obtaining the emissivity, if the difference between IR
value (in the middle of LCD) and TK value (at the lower
side of LCD) is too big, the obtained emissivity will be
incorrect. It´s necessary to obtain a new emissivity.
