*1: Slight haze, visibility about 20 km, sunny periods, weak scintillation.
*2: No haze, visibility about 40 km, overcast, no scintillation.
*3: Face the prism toward the instrument during the measurement with the distance at 10 m or less.
*4: Figures when the laser beam strikes within 30° of the reflective sheet target.
*5: Measurement at -30 to -20°C (-22 to -4°F) (Low Temperature Model)/50 to 60°C (122 to 140°F)
(Standard Model)
*6: The temperature of the lower limit is -30°C (-22°F) when using reflective sheet target. (Low Temperature
Model)
*7: Figures when using Kodak Gray Card White side (reflection factor 90%), brightness level is less than
5,000 lx and the laser beam strikes orthogonally the White side.
*8: Figures when using Kodak Gray Card White side (reflection factor 90%), brightness level is less than
500 lx and the laser beam strikes orthogonally the White side. (800 m or more)
*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: Figures may differ according to the country or the area.
*10: Accuracy is (2 + 2 ppm X D) mm for distance range 1.3 to 2 m.
*11: Accuracy is (5 + 2 ppm X D) mm for distance range 0.3 to 0.66 m or less.
*12: Figures are 4 ppm instead of 2 ppm at -35 to -30°C (-31 to -22°F).
*13: ISO 17123-4: 2012
*14: Figures are as follows when EDM eco mode is selected. Fine measurement: less than 2.0 sec + every
0.9 sec or less, Rapid measurement: less than 1.8 sec + every 0.6 sec or less, Tracking measurement:
less than 1.8 sec + every 0.4 sec or less
