8a MSA (Gage R&R) Measurement System Analysis (GR&R - Long Form) Supplier: Wells-Gardner Facility/Location: Burr Ridge Process: Work area: Date of MSA study: MSA managed
by: Gauge: Part number: AAA29501AG1 Nominal target: Gauge reference number: Part name: 21.5 Touch Panel with LCD Engineering tolerance Upper: Unit of measure: Measured feature: Lower: Gauge
resolution, Gres: Drawing reference: Eng. Tol. Range: ET = Up - Lo: Gauge Resolution Check: Gres / ET = If Gres / ET is greater than 10%, then the gauge is deemed to be inadequate for the
measurement application. INSTRUCTIONS: 1) CLEAR DATA. Enter the number of parts, technicians, and measurements. Press SET UP TABLE. 2) Select the parts at random, and number them. Identify
the feature on the part to be measured. 3) Select technicians whose normal job includes the use of this gauge to measure the selected feature. Samples (n): 4) Have each technician measure
each part in random order. The technicians must work independently. Do not let them help or observe each other while making the measurements. Technicians (t): Measurements (m): 5) Record the
data in the yellow fields of the table, and perform the necessary calculations. Gauge Repeatability & Reproducibility (R&R) Study: Technicians: TA: TB: TC: Average for each part Samples:
