4.5 Using Measurement Averaging☛ Measurement Averaging must be activated in Operation Options before averaging can take place.Refer to Section 7.2 for procedure.When averaging is activated, the averaging sequence will be requiredfor all functions (i.e., normal, storage, and pass/fail).Averaging should be used when measuring non-uniform samples,textured materials, and any dark or high chroma color, especially whenspecular excluded mode is used. When set to auto averaging, theinstrument will automatically require three measurements if an X, Y, or Zvalue of 2.5% or less is detected.The following example has an average setting of ‘‘2.’’To take an average measurement:1) Select measurement function (i.e, normal, storage, or pass/fail).2) Position target window over thefirst sample area to be measured.Sample3) Take measurement by loweringunit to target window onsample.- Release unit off of first area onsample when ‘‘READINGCOMPLETE’’ is displayed.4-7➩
