SONEL KT-640 THERMAL IMAGER 16
Infrared image transparency level and distance from the object can be adjusted using ver-
tical and horizontal sliders (using touch screen or Joystick). Selecting the lowest transpar-
ency value will result in only visual image being displayed. Pressing "IR" (or button) re-
sults in return to displaying full screen infrared image in real time mode.
It is advised to use FUSION mode for distances greater than 1,5m; In case of smaller dis-
tances significant displacement of both images can be observed (Parallax phenomenon).
5. Capturing and saving images with voice annotation
Caution. KT-640 utilizes external memory - SD card put inside the slot (15). If the SD card
is not inserted the camera will display infrared images in real time mode, and image can
also be freezed or being analysed, however it is not possible to store it in the memory.
The lack of SD card is indicated by the symbol displayed on status bar:
KT-640 displays image continuously, refreshing it 60 times per second. To capture an im-
age, press (6) button, which will freeze an image and will display menu elements on
screen. Information about the "freeze" mode is displayed on the bottom bar.
At this point:
- press button to save thermal image along with its corresponding visual image;
- click on temperature range icon (number defining upper range limit), or click on
icon (number defining lower range limit) to switch into manual adjustment of upper
and lower temperature range limits (see section 4.4). This operation allows to choose the
most optimal temperature ranges right after freezing an image on screen.
