Max 95% non condensing.
The effects of condensation are to be effectively counterac-
ted 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
•

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.
The atmospheric correction includes:
