Humidity
Type Protection
All instruments Max 95 % non condensing
The effects of condensation are to be effectively
counteracted by periodically drying out the instru-
ment.

8.9 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:
•
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 redetermined:
Reflectors
Navigation Light
(NavLight)
Automatic corrections
Use of scale correction
