Menu item "Buttons"
Fig. 114 Menu "Settings" – "Buttons"
Menu item "Buttons" serves to configure which actions shall be performed when hitting buttons A or T.
For this purpose, the options "NUC" and "Autoimage" in the submenu can be activated or deactivated
for A and "LASER on/off" for T. For button C a variety of additional operations is available. An active
option is checkmarked.
Activating the function "LASER on/off" will link the display of 1 (ROI 1), by using T, with the function of
the integrated laser pointer*: T activates or deactivates the laser pointer parallel to switching the ROI on
or off.
Following additional operations are at your disposal for button C:
■ IR-VIS pressing button C allows to switch between IR and VIS picture
■ IR-Merge insertion of IR picture within the VIS picture
■ IR-BGM activates the function "BG storage" (Menu item “BG memory”* - Page 46)
■ Overlay hide and show function of the menu
■ Palette invert. inversion of current colour palette
■ Autosave funct. activates the function "Autosave" (Menu item "Automatic"
■ – Page 56)
"NUC" homogenises the image (NUC: Non Uniformity Correction). When correcting these low
temperature deviations of the detector elements towards each other, which is due to technological
reasons, the live display of the thermal image is briefly interrupted. The correction is performed by the
system itself by changing the device temperature or within a fixed time interval or can be triggered by the
user by hitting A.
The function "Autoimage" serves to automatically adjust the temperature level and range: According to
the current temperature in the scene, the optimal setting of the temperature scale of the false-colour
presentation is selected. This guarantees that all temperatures of the scene are imaged in the thermal
image in colour or grey scales.
The laser pointer eases orientation in the thermal image. By default, it is adjusted to precisely
mark the centre of the thermal image at a distance of 2 m. This corresponds with the position of
Spot 1, unless it has not been shifted in the spot editor.
