calculated ratio of infrared energy emitted by an object to the energy emitted by
a blackbody at the same temperature (a perfect radiator has an emissivity of
1.00). For information on determining an unknown emissivity and for sample
emissivities, see section 19.2

I am currently installing 4 modules, each with 2 of the Raytek MI3 units. 7 of the units arrived with the normal display (Bottom Unit in photo), but 1 has only a full white block in the display. Is this indicative of a failed unit, or would this require external adjustments. These units always work when received, so I am unfamiliar with the required troubleshooting.
