Refraction：
When measuring horizontal distance and elevation, our instrument corrects the
atmospheric refraction and the earth curvature automatically.
The instrument supports of atmospheric refraction coefficient have three option,
they are 0.00, 0.14, and 0.20.
Note: The refraction of instrument has been set for K=0.00 when left factory .It also
can be set to other values
