Scale Correction

By entering a scale correction, reductions proportional to distance can be taken into
account.
• Atmospheric correction.
• Reduction to mean sea level.
• Projection distortion.
The distance displayed is correct if the scale correction in ppm, mm/km, which has
been entered corresponds to the atmospheric conditions prevailing at the time of the
measurement.
The atmospheric correction includes:
• Adjustments for air pressure
• Air temperature
For highest precision distance measurements, the atmospheric correction should be
determined with:
• An accuracy of 1 ppm
• Air temperature to 1°C
• Air pressure to 3 mbar
