Operation

LED-Lighting

Press the trigger for image recording and keep it pressed for 5 seconds. The white LED is activated.

Colour palette

Using the colour palette menu, incorrect colour presentations of the infra-red images displayed or recorded can be
changed. Different colour palettes are available for selection. Some palettes are better suitable for specific
applications than others and are set as required.
1: Grey scales offer a uniform, linear presentation of the colours for the best possible presentation of the details.
2: The colour palette, High contrast, presents colours with appropriate emphasis. This colour palette is suitable for
heavily pronounced temperature differences that can be presented as amplified contrast in the colour scheme
between high and low temperatures.
3: The colour palettes Ironbow and Rainbow are a combination of the high contrast and grey scales palette.

Reflection of the Background Temperature

The background temperature can be set at between 0 °C and 36 °C. Compensation of the reflected background
temperature is set on the display using the background settings. If the objects are very hot or cold, the apparent
temperature and measurement accuracy of the objective or object can be impaired, in particular if there is a low
degree of emission at the surface. By setting the reflected background temperature, in many cases, the
temperature measurement can be improved.

Fading the Image

By cross-fading an infra-red heatmap with an appropriately aligned visual image, heatmaps can be presented
clearer. With each heatmap, the camera also makes a normal recording of the image of the object, so that the
target object can be exactly and better compared to others.
