(*) Measuring range and accuracy depend on the correct reflection of the 
laser beam from the surface of the object to the instrument's sensor and on 
the brightness of the environment in which tests are performed.  
(**) Under favourable conditions (optimum object surface, room 
temperature). Under unfavourable conditions (intense sunshine, poor 
reflective properties of the object, high variations in temperature) the 
resolution in measurements >10m may be higher by ±0.15mm/m 
(±0.0018in/ft)
