Notes to the temperature performance:• The specified temperature performance presents preliminary findings based on
sample investigations using special test equipment.
• The temperature accuracies are achievable by following conditions
thermal equilibrium of the sensor
no temperature differences in the sensor package
the object fills the sensor field of view completely
homogenously distributed temperature on the object surface
high and uniform emissivity of the object surface in the interesting
infrared range
