Making sure that measuring instruments are properly calibrated is critical to quality manufacturing operations. A gauge that doesn't read accurately and repeatably can compromise the integrity of quality control and quality assurance documentation, and destroy confidence in measuring results. At their worst, inaccurate gauges can result in the production of nonconforming parts.

Gauge calibration represents an important, if not fully appreciated, manufacturing discipline. It should be viewed as an investment. Gauge calibration is the foundation upon which a quality program can be built.

More than simple adjustment

Gauge calibration determines the deviation from the true value of the indication supplied by a measuring instrument. The results of the calibration process can be used for gauge adjustment. Calibration goes beyond simple adjustment, however. A calibrated gauge can be traced back to a master source. Traceability provides the value added to the calibration process.
