Gage Agreement Folio Data Tab

The Data tab of the gage agreement folio contains a control panel and a sheet with the following four columns for entering data:

• Part is the identifier for the part that was measured.

• Measuring Device is the identifier for the gage that was used to obtain the measurement.

• Reading is the measurement obtained from the gage under investigation.

• Trial is used to help you keep track of multiple trials that are used in a particular study. For example, the first measurements of a part by a particular gage would be the first trial, the second measurement of the same part by the same gage the second trial, and so on.

As an example, suppose two scales are being compared for accuracy and precision. To compare them, three parts are weighed (in pounds) by both scales. Part 1 is measured four times: twice using the first scale and twice using a second scale. Part 2 and Part 3 are measured similarly. The same operator performs all the measurements. The resulting data is shown next. For example, the first row shows that Part 1 was measured by Gage 1 (the first scale), which produced a measurement of 66.32 pounds.
