The ScaleAssist function calculates a display-neutral scale depending on the
inside and outside temperature. This scale graduation can be used to detect
structural defects in buildings.

Setting emissivity and reflected
temperature
This function is only available if the
Image type
is set to infrared image.
You can choose between user-defined emissivity and 8 materials with
permanently set emissivity. The reflected temperature (RTC) can be set
individually.
Other materials can be imported into the instrument from an existing list
using the PC software.
Emissivity information:
The emissivity describes the capability of a body to emit electromagnetic
radiation. This is material-specific and must be adapted for correct
measurement results.
Non-metals (paper, ceramic, gypsum, wood, paints and coatings), plastics and
food have high emissivity, which means that the surface temperature can be
easily measured using infrared.
