About the End Wall Technique
We recommend this for increased precision where it is possible to strike the end wall. The End Wall method is also very useful for thicker wall tubes.

How To Use This End-Scan Technique
|
Avoiding Outliers
When scanning the end walls of highly reflective tubing with striations like shown in the image on the right, it is better to either cover the end with a coat of Maganaflux, Dynaflux, foot powder spray, white marking paint pen, or cover it with an end target to avoid outlier points. |
