Figure 10.17 Object Parameters dialog box
You use this command to set the object parameters Emissivity , Distance , T Reflected ,
T Atmosphere , Rel humidity , External optics , Optics transmission , and Optics
temperature . The parameters are selected by moving the joystick up/down and set
by moving the joystick left/right. These parameters settings will be used by all mea-
surement functions that have not been set locally.
➲ Please note the following:
■
The emissivity file can be stored at root level or at directory level. However, the
camera software prioritizes files that are stored at directory level and the directory
has to be selected in order to store the emissivity file in the camera memory. If the
camera software does not find an emissivity file at directory level, it searches for
similar files at root level and saves those instead.
■
If you enter an emissivity value less than 0.30 the emissivity box will begin flashing
to remind you that this value is unusually low.
■
The transmission factor is applied to the signal and not to the temperature
For more information about object parameters, see section 18 – Thermographic
measurement techniques on page 125.
