9. If necessary adjust the stand to assure the middle bead (E) still is in the centre of the cross.
10. To confirm the stand height is correct, use Equation 2 on the previous page to calculate the enlargement
factor (E). The physical distance between the outside beads in the alignment device is 10 mm.
By measuring the corresponding distance in the image (A-B, C-D, A-C, or B-D – or an average of the
four), the enlargement factor can be calculated as E= (L

/L

)-1=(L
2
/10)-1. The calculated value should fulfill
requirements in the table on the previous page. If not, adjust the height according to Equation 1, and
repeat the procedure.
