(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 target toward the prism during the measurement with the distance at 10 m or less.
*8
:
At the time of the tracking measurement.
