Distance Measurement - Long Range (LO mode)

The range of the long range measurements is the same for R400 and R1000.
Reflector
Standard prism (GPR1)
Range of measurement:
Display unambiguous:
Range A: Strong haze, visibility 5 km; or strong sunlight, severe heat shimmer
Range B: Light haze, visibility about 20 km; or moderate sunlight, slight heat
shimmer
Range C: Overcast, no haze, visibility about 40 km; no heat shimmer
Standard measuring
Long Range
*1 does not include radio transfer time to the CS.
Beam interruptions, severe heat shimmer and moving objects within the beam path
can result in deviations of the specified accuracy. The display resolution is 0.1 mm.
