*1 : Slight haze, visibility about 20 km, sunny periods, weak scintillation.
*2 : No haze, visibility about 40 km, overcast, no scintillation.
*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.
*6 : Figures when using Kodak Gray Card White side (reflection factor 90%) and brightness level
is less than 500 lx.
*7 : Face the target toward the prism during the measurement with the distance at 10 m or less.
*8 : Accuracy is (5 + 2 ppm X D) mm for distance range 0.3 to 0.66m.
*9 : Figures will change depending on the target reflection factor, weather conditions and location
conditions.
