TECHNICAL DATA
All accuracies are specified with Leica Geosystems precision 1.5” Red Ring Reflectors (delivered with each sensor) and a measurement mode of 2 seconds per point under stable environmental conditions. Full range is specified as 1.5 to 80 meters away from the laser tracker within a vertical range of +/- 45 ̊. All accuracies are stated in maximum permissible error (MPE). Typical results are half of MPE.
