first scan the temperature along the entire frame, next to the closed window. Select
the warmest area of the frame as the reference temperature, then e.g. a temperature
variation of 3 °C / 5°F.
Now steadily scan again, along all sides of the window, next to the frame. The
blue colour display and a slow tone series indicates a possible influx of cold air
with a difference of 3 °C / 5°F.
