• Non-prism mode (Diffusing Surface) D:
Measuring distance
• Non-prism long mode *2)*3) (Diffusing Surface) D:Measuring distance
*1)The initial time will be different by a condition.
*2)However, when the measurement distance is more than 500 m, or when the reflectance of the
measured surface is low, measurement time will become longer.
*3)Measurement distance: No more than 500m, When Kodak gray card (white surface) is used.
Laser class for distance measurement : Class 1(IEC Publication 825)
: Class I(FDA/BHR 21 CFR 1040)
Atmospheric Correction Range : –999.9 ppm to +999.9 ppm, in 0.1 ppm increments
