BCB mounting in vertical curves
NOTE
Limited absolute measurement accuracy and reproducibility!
BCB mounting in curves decreases the absolute measurement accuracy of the BPS,
since the distance between two bar codes is no longer exactly 30 mm.
In areas where the BCB is fanned out around curves, limitations of the reproducibility
must be expected.
Only partially cut the BCB at the cut mark.
Affix the BCB along the curve like a fan ((see figure 6.5)).
Ensure that the BCB is affixed without mechanical tension.
NOTE
No glossy gaps in the bar code tape!
Ensure that there are matt, bright surfaces behind the fanning in the BCB curves.
Polished, reflective, and high-gloss surfaces in the scanning beam may impair the
measurement quality of the BPS.
