Quality control checks
For the assessment of the precision the reproducibility of a measurement is
investigated.
The following precision checks (rules) are used to assess the system performance.
Violation of a rule is indicated by a flag.
Rule/Flag Comment
R 1(2.5s) This rule checks whether the precision is within the predefined limits.
A flag is generated if one value is outside ±2.5s.
R 1(3s) This rule checks for random errors.
A flag is generated if one value is outside ±3s.
R 2(2s) This rule checks for systematic errors.
A flag is generated if two values are outside ±2s.
