Distance measurement (IR: infrared)
•
Type infrared
• Carrier wavelength 0.780 µm
• Measuring system special frequency system
basis 100 MHz 1.5 m
• EDM type coaxial
• Display (least count) 1 mm
• Accuracy (Standard deviation acc. to ISO 17123-4)
The distance measuring accuracy is 5mm +
3ppm for the listed EDM measuring programs*
(6mm @ 300m; 1/4 inch @ 1500ft).
* ppm = mm / km

Range
Beam interruptions, severe heat shimmer
and moving objects within the beam path
can result in deviations from the specified
accuracy.
1) Strong haze, visibility 5km; or strong sunlight,
severe heat shimmer
2) Light haze, or moderate sunlight, slight heat
shimmer, visibility about 20km
3) Overcast, no haze, visibility about 40km; no
heat shimmer
