• By inputting the temperature and air pressure values, the atmospheric correction value is
calculated and set into the memory. Calculate the atmospheric correction factor as shown in the
following formula.
ppm = 282.59 -
1 + 0.003661 x air temperature (°C)

"30.2 Atmospheric Correction for High Precision Distance Measurement"
•If the weather correction is not required, set the ppm value to 0.
