An electrode manufacturer wants to evaluate the measurement system that measures the outer diameter of electrode shafts to determine whether the system accurately measures the shaft within the 0.05 mm tolerance.
An operator measures a reference shaft with a known outer diameter of 12.305 mm 50 times.
