1
Where target is larger than the laser footprint of the laser beam, with perpendicular angle
of incidence and measured under Renishaw calibration conditions to Kodak white card (90%
reflectivity).
2
Accuracy is defined as the degree of conformity of the measured sample mean range to its
actual (real) value, measured with reference to a total station under Renishaw test conditions.
3
Predicted accuracy and precision figures extrapolated from 10 m to 150 m.
4
Precision is defined as the repeatability, or reproducibility, to which the reported value recurs
upon subsequent measurement, 1
σ
throughout measurement range.
