Application measurement EN Figure 6-12 statistical indicators Calculate and display the Average, Max, Min, Parent Standard Deviation, Sample Standard Deviation, and Procedure Ability Index for up to 1000 measurement data. The calculation formula is as follows: ⚫ The n in the formula represents the number of valid data. ⚫ Hi and Lo use the upper and lower limits of the comparator. ⚫ The process capability index refers to the ability to achieve process quality, which can be understood as the degree of quality deviation and deviation that a process has. Generally, the values of Cp and Cpk can be used to evaluate process capability (as shown below): Cp, CpK>1.33......
Sufficient process capability 1.33 ≥ Cp, CpK>1.00... Appropriate process capability 1.00 ZCp, CpK, etc. Insufficient process capability Note: Copyright © Qingdao Hantek Electronic Co., LTD HBT3000 series user manual 33
