*1: Slight haze, visibility about 20 km, sunny periods, weak scintillation.
*2: No haze, visibility about 40 km, overcast, no scintillation.
*3: Measurement at -30 to -20°C (-22 to -4°F) (Low Temperature Model)/50 to 60°C (122 to 140°F)
(Standard Model)
*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 30000 lx (a little cloudy).
*6: Figures when using Kodak Gray Card Gray side (reflection factor 18%) and brightness level is less
than 30000 lx (a little cloudy).
*5,*6:When performing reflectorless measurement, the possible measurement range and precision
will change depending on the target reflection factor, weather conditions and location
conditions.
*7: Face the prism toward the instrument during the measurement with the distance at 10 m or less.
*8: At the time of the tracking measurement.
