Working with measurement tools 17
for longer distances. The External IR window compensation must be activated if a protec-
tive window or external lens is used.
17.5.3 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
17.5.4 Procedure
You can set the object parameters globally. You can also change the Emissivity , Reflected
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.
17.5.4.1 Setting global parameters
Follow this procedure:
1. Push the joystick to display the menu system.
2. Use the joystick to go to ( Measurement parameters ).
3. Push the joystick to display a submenu. Use the joystick to select one or more of the
global object parameters:
• ( External IR window compensation )
• ( Object distance )
• ( Atmospheric temperature )
• ( Relative humidity )
• ( Reflected temperature )
• ( Emissivity )
4. Push the joystick to display a dialog box.
5. Use the joystick to change the parameter.
6. Push the joystick. This closes the dialog box.
17.5.4.2 Changing local parameters
You can change the local parameters for a measurement tool.
A P next to the measurement tool on the screen indicates that local parameters are acti-
vated for the tool.
