Scale Correction
Use of scale correc-
tion
By entering a scale correction, reductions proportional to distance can be taken into
account.
• Atmospheric correction.
• Reduction to mean sea level.
• Projection distortion.
Atmospheric correc-
tion
D1
The slope 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
• Relative humidity
For highest precision distance measurements, the atmospheric correction should be
determined with an accuracy of 1 ppm. The following parameters must be redeter-
mined:
• Air temperature to 1 °C
• Air pressure to 3 mbar
• Relative humidity to 20 %
