Error Message Meaning What to do

13.2 Atmospheric Correction

The speed at which light travels through the air varies depending on the temperature and

atmospheric pressure.The R-300X series is designed to measure distances at the speed of light

in order to measure accurately,atmospheric correction needs to be used.The instrument is

designed to correct for weather conditions automatically if the temperature and pressure are

input.Correction is then carried out based on the following formula.

Calculation formula:

K= (276.26713 - 78.565271 • P ) x10-6

K:Atmospheric Correction Constant

P:Atmospheric pressure (hPa)

t:Temperature(°C)

Distance after Atmospheric Correction D = Ds (1+K)

Ds:Measured distance when no Atmospheric Correction is used.
