7.14 Setting the emissivity as a surface property
7.14.1 General
To measure temperatures accurately, the camera must know what kind of surface you
are measuring. You can choose between the following surface properties:
Matt.
Semi-matt.
Semi-glossy.
For more information about emissivity, see section 14 Thermographic measurement
techniques, page 32.
7.14.2 Procedure
Follow this procedure:
1. Push the center of the navigation pad. This displays a toolbar.
2. On the toolbar, select Settings
. This displays a dialog box.
3. In the dialog box, select Measurement parameters. This displays a dialog box.
4. In the dialog box, select Emissivity. This displays a dialog box.
5. In the dialog box, select one of the following:
Matt.
Semi-matt.
Semi-glossy.
7.15 Setting the emissivity as a custom material
7.15.1 General
Instead of specifying a surface property as matt, semi-matt or semi-glossy, you can spec-
ify a custom material from a list of materials.
For more information about emissivity, see section 14 Thermographic measurement
techniques, page 32.
7.15.2 Procedure
Follow this procedure:
1. Push the center of the navigation pad. This displays a toolbar.
2. On the toolbar, select Settings
. This displays a dialog box.
3. In the dialog box, select Measurement parameters. This displays a dialog box.
4. In the dialog box, select Emissivity. This displays a dialog box.
5. In the dialog box, select Custom material. This displays a list of materials with known
emissivities.
6. In the list, select the material.
7.16 Changing the emissivity as a custom value
7.16.1 General
For very precise measurements, you may need to set the emissivity, instead of selecting
a surface property or a custom material. You also need to understand how emissivity and
reflectivity affect measurements, rather than just simply selecting a surface property.
