Working with measurement tools
13.4.3 Moving and resizing a box, circle, or line tool
Note You can also move and resize the measurement tool by touching the screen.
Follow this procedure:
1. To select the measurement tool, touch the tool on the screen. The tool is now dis-
played with one or more handles.
2. Push the navigation pad—or touch and hold the tool. This displays a context menu.
3. Select
(Move/resize) and push the navigation pad. This displays a submenu.
4. Use the navigation pad to select one of the following:
• Select
(Resize) to change the size of the tool.
• Select
(Move) to move the tool.
• Select (depending on the tool)
tool or
Rotate & center line or to rotate and center the line tool.
5. Push the navigation pad up/down and left/right to resize or move the tool.
6. When completed, push the navigation pad and select
7. Push the navigation pad to confirm and exit the menu mode.
13.5 Changing the measurement parameters
13.5.1 General
For accurate measurements, it is important to set the measurement parameters.
Note During normal operation there is typically no need to change the default meas-
urement parameters, see section 13.5.3 Recommended values.
13.5.2 Types of parameters
The camera can use these measurement 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.
Note The camera can be configured to automatically measure the distance when
an image is saved. With this setting, the Object distance parameter in the image data
is automatically updated with the measured distance when an image is saved. (There
is no effect on the Object distance setting in live mode.) For more information, see
section 6.4 Laser distance meter and laser pointer.
• 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.
