If the object one is trying to measure has an emissivity of 0.5 but the device assumes it is a perfect blackbody with an emissivity of 1.0 then the calculated temperature will be lower than it really is perhaps significantly underestimated. If emissivity is set too low on the noncontact measuring device then the temperature is overestimated.
