Product Manual

The atmospheric correction includes:
•
Adjustments for air pressure
•
Air temperature
For highest precision distance measurements, the atmospheric correction should be determined
with:
•
An accuracy of 1ppm
•
Air temperature to 1°C
•
Air pressure to 3mbar
Atmospheric corrections in ppm with temperature [°C], air pressure [mb] and height [m] at
60 % relative humidity.
