Measurement accuracy/Least Count in Measurement/Measurement Time
• Prism mode D:
Measuring distance
• Non-prism mode (Diffusing Surface) D:
Measuring distance
• Non-prism long mode *3) *4) (Diffusing Surface) D:
Measuring distance
*1)More than 2m
*2)The initial time will be different by a condition.
*3)Measurement distance: No more than 500m, When Kodak gray card (white surface) is used.
*4)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.
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
Prism Constant Correction Range : –99.9 mm to +99.9 mm, in 0.1 mm increments
Coefficient Factor : Meter / Feet
International feet 1meter = 3.2808398501 ft.
