Review on 6 Inch Master Precision Level in Fitted Box - Accuracy: 0.0002''/10'' - Enhanced SEO by Richard Alemayehu

is delicate, but the ampoule runs very poorly. Vial deformation prevents self-test/calibration. How do you say? Because of the inability to calibrate. I spent half an hour trying to get the approximate range on a decent class B surface plate until I broke the 10k scale. I found that the sides of the base weren't parallel within the allowable tolerance, but then I took out the vial and in fact it was deformed about 20 degrees from the center. You will need to purchase a quality replacement vial to make it work. It seems that someone in China thought that stupid Americans would not disassemble it and would not understand the scam.
