* D4 =3.27 for 2 trials and 2.58 for 3 trials.UCLR represents the limit of individual R's.Circle those that are Gage discrimination low
beyond this limit.Identify the cause and correct.Repeat these readings using the same appraiser and unit as originally used or
discard values and re-average and recompute R and the limiting value from the remaining observations. For information on the theory and constants used in the form see MSA Reference Manual, Fourth edition.
