1. Applies for 100% target reflectivity (white painted wall), low background illumination, 25°C.
2. Applies for 10 to 500% target reflectivity, high background illumination, -10°C to +50°C.
3. Tolerances apply from 0.05 m to 10 m with a confidence level of 95%. The maximum tolerance may deteriorate to 0.1 mm/m between 10 m to 30 m and to 0.15 mm/m for distances above 30 m.
4. Applies for 100% target reflectivity, background illumination between 10'000 lux and 30'000 lux.
5. After user calibration. Additional angle related deviation of ±0.01° per degree up to ±45° in each quadrant. Applies at room temperature. For the whole operating temperature range the maximum deviation increases by ±0.1°.
