jets.
Humidity
Type Protection
Zoom instrument Max 95% non condensing.
The effects of condensation are to be effectively counteracted by
periodically drying out the instrument.
The following automatic corrections are made:
Line of sight error
Tilting axis error
Earth curvature
Standing axis tilt
Vertical index error
Refraction
Compensator index error
Circle eccentricity
15.7 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 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.
