" 0 " is the length of travel. and
"E" is the cosine error , in pam - per - million .
Enter the va l lie for " E" in line " 6" , column ';A". ( If 5 = 0 .25 mm and "0" - 506 mm ( 20
inches). then "[" = O.03ppm.)
d. Mu ltiply the cosine error (in ppm ) by the length of travel. and enter in line " 8", co lumn
" 8 ". (0. 03 ppm X 5 00 mm .. 0. 00001 mm or 0.0000005 inch ).
9. Add line "4" through line "8" to dete rmine the total maximum error magnitude. (0.00147
mm, 0. 0000 56 inch ).
Enter this number in lin e "9", co lumn " If' and co lumn "e".
10 . Subtract line " 9" from line " 3" (0. 00277 mm, 0. 000109 in ch ).
As long as this number is po s iti ve. yo ur La se r Meas ur ement Sys tem will provide en ough
accuracy for yo ur application.
