Scale correction
MTS-800 can carry out the distance correction of Average Elevation and
Projection by setting a scale factor. If there's a need for this correction, the scale
factor should be calculated and entered in instrument's memory by user. Please
refer to some professional book about surveying for more details.
The correction will be 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
l
Note: When the scale factor is set, it will affect all functions relate to
coordinate measuring .
l
Scale factor input range: 0.98-1.02 .Default value is 1.000000(This means no
correction is carried out.)
