*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: The temperature of the lower limit is -30°C ( -22°F) when using reflective
sheet target. (Low Temperature Model)
*5: Figures when measured at -30°C (-22°F) or more. (Low Temperature
Model)
*6: Figures when the laser beam strikes within 30° of the reflective sheet
target.
*7: Figures when using Kodak Gray Card White side (reflection factor 90%)
and brightness level is less than 30000 lx (a little cloudy).
*8: Figures when using Kodak Gray Card Gray side (reflection factor 18%)
and brightness level is less than 30000 lx (a little cloudy).
*7,*8: When performing reflectorless measurement, the possible measurement
range and precision will change depending on the target reflection factor,
weather conditions and location conditions.
*9: Face the prism toward the instrument during the measurement with the
distance at 10 m or less.
*10: At the time of the tracking measurement.
