more accurately, emissivity corrections are necessary. Adjusting the
emission value usually allows the product to more accurately calculate
the actual temperature estimate.
Warning:
It is difficult to determine the actual surface temperature with an
amplitude less than 0.60 accurately and consistently. Even if the
emissivity and the background of the reflection are adjusted correctly, the
lower the emissivity, the greater the possible error in the calculation of
the product of the results of the temperature measurement.
