Instruction for Large Diameter Measures
|
VTube is immune to diameter sizes if you follow the wide-scan technique to measure larger diameters. If a diameter surface stripe does not cover enough angular distance, then the math engine loses accuracy in calculating the centerline of a straight.
|
How Large VTube-LASER Measure?
|
Using this method, it is possible to scan any size tube or pipe the arm can reach. The limitation is not the scanner size. |
