The Linearity study feature within GageList assesses the accuracy of a measurement system across its expected operating range. By measuring known standards at various points along the scale, this tool helps identify if the measurement device exhibits proportional errors. Understanding and quantifying linearity ensures that measurements remain reliable and consistent regardless of the magnitude of the characteristic being measured.
To view or add studies, see MSA Overview.
Performing the study
- Add a new MSA study with the study type set to “Linearity Study (AIAG MSA v4)”.
- Fill in the Study Information section.
- Enter measurement data for the study. This can be done by using Guided Trials or entering values in the Measurement Data section.
- Once the Measurement Data section is complete, click Run Report to generate the study results.
- The study can be marked as complete and a PDF report can be exported.
Entering data using Guided Trials
- Scroll to the Guided Trials section.
- Select the randomization options for the study. These include:
- Randomize Parts: Selects a random part number for each measurement. If disabled, parts are selected in order.
- Randomize Appraisers: Selects a random appraiser for each measurement (if alternating) or trial (not alternating). If disabled, appraisers are selected in order.
- Alternate Appraisers: Selects appraisers between measurements. If disabled, the appraiser must complete their trial before the next appraiser is selected.
- Click Enter Data.
- Begin recording your measurements based on the displayed appraiser, part and trial.
- Once completed, click Done.
