[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°. |
