20.3.1 Measurement parameters

20.3.1.1 General
For accurate measurements, you must set the object parameters.
20.3.1.2 Types of parameters
The camera can use these object parameters:
• Emissivity, i.e., how much radiation an object emits, compared with the radiation of a
theoretical reference object of the same temperature (called a "blackbody"). The op-
posite of emissivity is reflectivity. The emissivity determines how much of the radiation
originates from the object as opposed to being reflected by it.
• Reflected temperature, which is used when compensating for the radiation from the
surroundings reflected by the object into the camera. This property of the object is
called reflectivity.
• Distance, i.e., the distance between the camera and the object of interest.
• Relative humidity, i.e., the relative humidity of the air between the camera and the ob-
ject of interest.
• Atmospheric temperature, i.e., the temperature of the air between the camera and the
object of interest.
• Window compensation, i.e., the temperature of any protective windows, etc., that are
set up between the camera and the object of interest. If no protective window or pro-
tective shield is used, this value is irrelevant and should be left inactive.
20.3.1.3 Recommended values
