Temperature, pressure, and humidity affect the measurement values that your Leica tracker acquires. Compensation is provided for measurements based on the changes in these values, which calculate the refraction index of IFM / ADM.
You can use a Meteo Station to provide these values, or you can manually enter these values if you do not have a Meteo Station. When the Meteo station is enabled, the refraction is calculated every 30 seconds. For changes that are greater than 5 ppm, the parameters are updated accordingly.
To manually alter these values, do one of the following:
From the Machine Options dialog box (Edit | Preferences | Machine Interface Setup), edit the Leica environmental parameters. If you have a Meteo station but would like to manually edit the values, deselect the Use Temperature Station option.
From the Leica status bar (View | Status Bar | Tracker), edit the environmental values by clicking on the value and typing the new value.
