Air pressure range: 560~1066hPa (interval 0.1hPa) or 420~800mmHg (interval 0.1mmHg) or
16.5~31.5inHg (interval 0.1inHg)
The setting of Air pressure is same as temperature setting
If the atmospheric correction value calculated from the temperature and air pressure exceeds
the range of ±999.9×10ˉ

PPM, the operation will return to step 4 automatically, and you
should enter the data again
4.2 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.
