4.4. Calibration passed
◆
For the instrument to pass calibration, the data must meet the statistical criteria which has 2
conditions:
1- The coefficient of variations must be within their limits (See Tab.5-2 Coefficient of variation
limits, page 5-27 ).
2- The difference between the target value and the average for each parameter calibrated, must be
less than 20%.

Passed calibration is as follows:
4.5. Calibration failed
◆
For the instrument to fail calibration, the data must meet the statistical criteria which has 2
conditions:
1- The coefficient of variations are out of their specified limits (See Tab.5-2 Coefficient of variation
limits, page 5-27 ).
2- The difference between the target value and the average for each parameter that failed
calibration, is greater than 20%.
