19 Working with measurement tools and isotherms

19.6 Moving measurement tools

19.6.1 Procedure

Follow this procedure:
1. Push the Menu/Back button.
2. On the main menu, go to the Tools button
3. On the Tools menu, select Adjust tools
4. Select the measurement tool that you wish to move. This will display a submenu.
5. On the submenu, select Move and push the joystick. This will make the center of the
measurement tool turn blue. You can now move the measurement tool using the
joystick.

19.7 Resizing areas

19.7.1 Procedure
Follow this procedure:
1. Push the Menu/Back button.
2. On the main menu, go to the Tools button
3. On the Tools menu, select Adjust tools
4. Select the measurement tool that you wish to resize. This will display a submenu.
5. On the submenu, select Resize and push the joystick. This will create resizing han-
dles for the area. You can now resize the area using the joystick.

19.8 Changing object parameters

19.8.1 General

For accurate measurements, you must set the object parameters. This procedure de-
scribes how to change the parameters.

19.8.2 Types of parameters

The camera can use these object parameters:
• Emissivity, which determines how much of the radiation originates from the object as
opposed to being reflected by it.
• Reflected apparent temperature, which is used when compensating for the radiation
from the surroundings reflected by the object into the camera. This property of the ob-
ject is called reflectivity.
• 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.
• External optics temperature, 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
protective shield is used, this value is irrelevant.
• External optics transmission, i.e., the optical transmission of any protective windows,
etc. that are set up between the camera and the object of interest.

19.8.3 Recommended values

If you are unsure about the values, the following are recommended:
