Reference: Distance correction in the coordinates setting-out measurement.
The total station can carry out the distance correction of Average Elevation and
Projection by setting a scale factor.
The correction is performed using the following formula:
（1）The distance on the projection plane:
HDg = HD×scale factor
HDg：The distance on the projection plane.
HD： The distance on the ground.
（2）The distance on the ground:
HD = HDg/ scale factor
z Note: When the scale factor is set, it will affect all functions related to coordinate
measuring.
z Scale factor input range: 0.98-1.02. Default value is 1.000000(This means no
correction is carried out.)
z The steps to change scale factor are described next.
