SECTION 5PASS/FAIL OPERATIONSubjects covered in Section 5 are:5.1 Adjusting Tolerance Values5.2 Pass/Fail MeasurementThe Pass/Fail feature will indicate a pass or fail signal on a samplemeasurement based on the tolerance assigned to a reference.Tolerance limits can be set for all available color spaces.5.1 Adjusting Tolerance ValuesThe tolerance adjustment feature allows the user to select the colorspace, illum/obs and tolerance values for each reference.-- ∆L*a*b* and ∆L*C*H* method allows pass/fail indication on ∆Εor all attributes.-- ∆XYZ or ∆Yxy method allows pass/fail indication on all attributes.-- ∆Wht or ∆Yel method allows pass/fail indication on availableattributes.-- ∆ECMC method allows adjustment of ‘‘l’’ (lightness factor) and ‘‘c’’(chromaticity factor), and pass/fail based on ‘‘cf’’ (commercialfactor).The pass/fail method selected will cause the tolerance editingprocedures to differ. Each tolerance method selected will be coveredseparately. The initial tolerance procedure will be covered in steps 1 - 4.Thereafter, each tolerance method will start at Step 5.5-1
