**Bias and Linearity**

We purchased a New Digimatic Micrometer of a reputed make. We conducted the Bias and Linearity study with Slip Gauge, and we anlysed the result using the Regression. The R square value we got from the study if 0.69 as against 0.98. can any one comment on the study result. What might went wrong with the Micrometer as its new. At the same time we conducted GR&R study with this instrument and we got GR&R value less than 10%.
