3.2 Setting of the Atmospheric Correction

The infrared emitted by the Total Station varies with the air temperature and
pressure. Once the atmospheric correction value is set the instrument will correct
the distance measuring result automatically.
Air pressure： 1013hPa
Temperature： 20℃
The calculation of atmospheric correction ：
ΔS =273.8 0.2900 P / （ 1 + 0.00366T ）(ppm)
ΔS：Correction Coefficient （Unit ppm）
P: Air Pressure （Unit : hPa If the unit is mmHg , please convert using
1hPa = 0.75mmHg
T: temperature （ unit℃）
