Trend analysis
When it comes to knowing when to recalibrate a gage, historical trend analysis is a trustworthy way to utilize data to assess need. Trend analysis looks at naturally occurring drift over time in combination with usage frequency. Every gage will have a specific and unique amount of drift that occurs as it is used over time. This refers to the amount of deviation that just happens naturally. Every gage will be a little different. The usage frequency refers most often to the amount that a particular gage is utilized in a facility. The frequency can also include data on where in a facility a gage is housed, which can impact how often it is used. Using trend analysis to determine how often a gage needs to be recalibrated can decrease the cost of unnecessary calibration and decrease the risk of inaccuracy due to too infrequent calibration.
