Image correction

To correct possible image deviations in vertical and/or horizontal direction,
you can use 'vertical' and/or 'horizontal' correction of the calibration function.
The vertical and horizontal correction can be adjusted independently. The total
correction range in both directions is +/- 3% and is adjustable in 0.1% steps. In
practice this means that you can specify a calibration factor between 0.970 and
1.030.
If you use the optional Scan Station (Scan To File), both factors must be
Note:
set to 1.000.
