Emissivity – The user can select the emissivity for the material being imaged. To achieve
correct temperature measurement the emissivity value must be set correctly. An emissivity table is included in
Section 6.
NOTE
: Caution should be observed in using the emissivity control – the user should explore the effect on
the observed temperature of an object when different emissivities are selected. Low values of
emissivity should be used only with extreme caution as large errors in temperature readings may be
obtained with only small errors in emissivity. Care should also be taken to avoid reflections from
hot/cold objects in the vicinity.
