How to input meteorological correction of total station

1. When the temperature error is 1 degree, it will bring an error of 1mm/km to the distance value; [

2. When the measurement error of air pressure is 1 hectopascal, it will bring an error of 0.3mm/km to the distance value;

3. The meteorological reference point of total station is generally 15 degrees, 10 13 hectopascals (or 760mmHg).

Therefore, if the real-time meteorological parameters are not input, when the temperature is 30 degrees, the error of 15mm/km will be brought to the ranging results.

It is suggested that the average temperature predicted according to the weather forecast of the day is temperature, and 10 13 hectopascals (or 760mmHg) is atmospheric pressure, which can generally meet the requirements of ordinary lofting.
