*3 : Figures when both the elevation and depression angles of the laser beam are within 15° and
the instrument is facing the 360° Prism.
*4 : Figures when the laser beam strikes within 30° of the reflective sheet target.
*5 : Figures when using Kodak Gray Card White side (reflection factor 90%) and brightness level
is less than 5,000 lx.
