Atmospheric corrections
The settings on this panel define the atmospheric ppm and the refraction.
For standard applications, the distance is corrected due to atmospheric influen-
ces. The geometrical correction and the projection distortions are set to 0.00.
Heights are reduced with the standard refraction coefficient.
Refer to the product specific User Manuals for information on calculations.
Select Leica Captivate - Home: Settings\TS instrument\Atmospheric cor-
rections.
The atmospheric distance corrections are derived from the dry air temperature,
air pressure or elevation above mean sea level MSL, and the relative air humid-
ity or wet bulb temperature.
