I had about the same problem with vt02, really vt02-04 images contains more information with respect it gives, but
it is difficult to get informations from is2 fluke file and probabily illigal without permission.
Finally I decided to realize a sw that works directly on the images produced by smartview to get and mark the
the temperatures of the thermal map. In practice, when the markers central/max/min are activated on vt02 camera,
it get the central temperature on the memorized image but after that, it is possible take note of the temperature of the
minimum marker in the same image shifting the central point camera. In this way, because the scale is continue, by the color
scale I get the entire map temperatures.
