Working with measurement tools16
16.5 Changing object parameters
16.5.1 General
For accurate measurements, you must set the object parameters.
16.5.2 Types of parameters
The camera can use these object parameters:
• External IR window compensation, i.e., the temperature of any protective windows,
external lenses (e.g., the close-up lens), etc., that are set up between the camera and
the object of interest. If no protective window, protective shield, or external lens is
used, this value is irrelevant and should be left inactive.
• Object distance, i.e., the distance between the camera and the object of interest.
• Atmospheric temperature, i.e., the temperature of the air 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.
• 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”.
• Emissivity, i.e., how much radiation an object emits, compared with the radiation of a
theoretical reference object at 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.
Note There is an Emissivity mode setting, which you can use to enter the emissivity
by material instead of by value. Select
(Settings) > Device settings > Set up cam-
era > Emissivity mode > Select from materials table.
Of the object parameters, Emissivity is the most important parameter to set correctly. If
the Emissivity is set to a low value, the Reflected temperature also becomes important.
The parameters Object distance, Atmospheric temperature, and Relative humidity are
relevant for longer distances. The External IR window compensation must be activated if
a protective window or external lens is used.
16.5.3 Recommended values
If you are unsure about the values, the following are recommended:
Object distance 1.0 m (3.3′)
Atmospheric temperature
20°C (69°F)
Relative humidity 50%
Reflected temperature 20°C (69°F)
Emissivity 0.95
16.5.4 Procedure
You can set the object parameters globally. You can also change the Emissivity, Re-
flected temperature, and Object distance parameters locally for a measurement tool.
Local parameters are normally only effective for a fixed setup, where each measurement
tool is set to a specific object of interest. In a general handheld application, the global pa-
rameters are usually sufficient.
Note Of the object parameters, Emissivity and Reflected temperature are the two most
important to set correctly in the camera.
