Measurement Bias
Difference between the average observed measurement and a known reference value.
Examples
- 01A gauge that reads 0.02 mm larger than the master ring has a measurement bias of 0.02 mm.
- 02The supplier is asked for measurement bias studies on all gauges used for the customer's key characteristics, not only calibration certificates.
- 03When the measurement bias is found, all results since the last check are corrected, and parts near the limit are re-measured.
