23. Tips and notes
• Measuring errors may occur when operating the product
outdoors due to light refraction or sunlight. Perform
measurements in suitable light conditions.
• Due to their physical properties, the following surfaces
may falsify the measurements:
- Transparent surfaces (e.g. glass, water)
- Reflective surfaces (e.g. glass, shiny metal)
- Porous surfaces (e.g. insulating materials)
- Structured surfaces (e.g. roughcast, natural stone)
