●The calculating formula for atmospheric correction is as follows: (calculating
unit：meter)
PPM = 273.8 - 0.2900 ³ Pressure Value（hPa）
1 + 0.00366 × Temperature value（‵）
If the pressure unit adopted is mmHg: make conversion with:
1hPa = 0.75mmHg.
●The standard atmospheric condition of R SERIES Total Station instrument (e.g. the
atmospheric condition under which the atmospheric correction value of the instrument is
zero):
Pressure：1013 hPa
Temperature: 20‵
If regardless of atmospheric correction, please set PPM value as 0.
