The following parameters are shown:
Samples: it is the number of acquired results.
Minimum: it is the minimum value between the results of the Inspection.
Maximum: it is the maximum value between the results of the Inspection.
Range: it is the range value according to ISO norm.
Average: it is the average value of the results of the Inspection.
STD (σ): it is the standard deviation (indicated with the Greek letter “Sigma”) of the results of the Inspection.
3σ/X: it is the value of the “3 sigma percentage” parameter (3 times the standard deviation) over the average value according to ISO norm.
X-3σ: it is the value of the “mean minus 3 times the standard deviation (sigma)” parameter according to ISO norm.
X+3σ: it is the value of the “mean plus 3 times the standard deviation (sigma)” parameter according to ISO norm.
Cp: it is the Cp value according to ISO norm.
Cpk: it is the Cpk value according to ISO norm.
OK: it is the percentage value of the results between minimum and maximum limit.
Low: it is the percentage value of the results under the minimum limit.
High: it is the percentage value of the results over the maximum limit.
