For this reason, if you need to install an optional contact point with an outside diameter smaller than 7 mm, use a washer (with outside diameter of at least 7 mm, inside diameter of 3 mm, and thickness of approx. 0.5 mm) placed between the contact point and the spindle.Note 3: Being xed by only two retaining screws, the back cannot be rotated by 90 degrees to change the orientation of the lug.InchOrder No.Graduation (in)Range (range/rev) (in)Accuracy* (in)Repeat-ability (in)Dial readingMeasuring force (N)w/lugFlat-backFirst 1 Rev/2.5 Rev/10 RevRetrace1921T-101921TB-100.0010.1 (0.04)±0.001/±0.001/—0.0002±0.00020-20-01.8 or less1923T-101923TB-100.00050.05 (0.02)±0.0005/±0.005/—0.00016±0.00010-10-01.8 or less1925T-101925TB-100.00010.025 (0.01)±0.0002/±0.0002/—0.0001±0.000030-5-01.8 or less ANSI/AGD type* Completed products inspection is performed in the vertical orientation (contact point downward) and the stated accuracy is guaranteed.* Completed products inspection is performed in the vertical orientation (contact point downward) and the stated accuracy is guaranteed.
