Hi all,
We are doing the GR&R on our noise tester. The upper specification limit of the noise is 30. The nominal of the noise in current process is 28. When I use the minitab on GR&R ANOVA Crossed method (study variation) it is very hard to get the GR&R below 30%. The repeatability variable is very high although the range among the 3 trial runs from a particular operator and a particular sample is only 1 point something.
Is any method that I can use to study the tester GR&R in this case?
Thanks and regards
YJ
