8.6 Measurement parameters
For accurate temperature measurements, it is important to use appropriate measure-
ment parameters:
• Emissivity : The emissivity determines how much of the radiation originates from the
object as opposed to being reflected by it.
• Reflected temperature : This parameter is used to compensate for the radiation from
the surroundings reflected by the object into the camera.
• Relative humidity : The relative humidity of the air between the camera and the object
of interest.
• Atmospheric temperature : The temperature of the air between the camera and the ob-
ject of interest.
• Distance : The distance between the camera and the object of interest.
Note During normal operation there is typically no need to change the default meas-
urement parameters, see section 8.6.2 Recommended values , page 21.
8.6.1 Setting measurement parameters
Emissivity is the most important measurement parameter to set correctly. If the Emissivity
is set to a low value, the Reflected temperature also becomes important. The parameters
Relative humidity , Atmospheric temperature , and Distance are relevant for longer
distances.
To set the measurement parameters, do the following:
1. Select Settings > Measurement parameters .
2. Select the measurement parameter you want to change.
