Colour palettee

Description of the colour palettes
Different colour palettes can be used to display the temperature differences of the infrared image. The PCE-TC 33N offers five colour palettes common for thermographic images: spectrum (rainbow), iron, cold, white (hot), black (hot).
The coloured palettes work best with large temperature differences and provide additional coloured contrast. For some images, black and white images are nevertheless more suitable. Test on a case-by-case basis which colour palette offers the best representation.
Here the infrared images of a component are shown with the different colour palettes:

Emissivity

Desscription of the emissivity
Every object with a temperature above absolute zero emits thermal radiation. The emissivity is the indicator of how much thermal radiation this object emits in contrast to an ideal thermal radiator, the black body. The emissivity is therefore always between 0 … 1 (0 … 100 %). For many applications, it is sufficient to measure with the standard value of 0.95. For a correct temperature measurement, however, it is essential to take the correct emissivity of the surface to be measured into account.

Set emissivity
You can change the emissivity via the submenu “Emissivity”.
Press the MENU key. The current function is highlighted in blue.
The selection can be changed with the navigation keys UP or DOWN.
Confirm the selection of the “Emissivity” function with the RIGHT navigation key. A list of the selectable emissivities appears.

Maintenance

Cleaning the meter

Use a slightly damp lint-free cloth and only gentle cleaning agents. Do not use abrasive agents or strong solvents for cleaning. If necessary, the lenses and the screen should be cleaned with special cleaning agents for optical glass.

Cleaning the infrared lens

Prevent damage to the infrared lens when cleaning it. The lens has a high- quality anti-reflective coating. Therefore, clean the lens carefully and without applying strong pressure to avoid damaging the anti-reflective coating. To clean the lens, use a special cleaning solution, e. g. customary alcohol-based lens cleaner and a lint-free textile or paper towel.
Dampen the lint-free cloth or towel with the cleaning solution. Remove excess liquid by squeezing the cloth or by absorbing it through an additional dry cloth. Then wipe the lens surface with circular movements. If it is necessary to repeat this step, use a new cloth.
