QX/T19—20033 Data processing
) Calculate the average value of the total number of measurements of the first group and the second group by formula (13): A= 4. + 4,
A—the average value of the first group of 10 readings of the total radiometer and the average value of the second group of 1V readings of the total radiometer as the value, b) Calculate the corresponding sensitivity h of the converter according to formula <14>: K, = K
In the formula!
The sensitivity of the total radiometer is VW
The average value of the reading of the night meter is 1(V).
1Within one year, use the same method to inspect the case every three months. Calculate the annual stability % according to formula (1): r =
K×100%
Wherein:
K is the maximum value of the four test ranges within one year and the sensitivity K is the half mean value of the relative sensitivity of the four tests within one year. The test results shall meet the requirements of 5.2.10.

7.5. Classification
The standard stipulates that defects are divided into major and minor defects. 7.5.2 Single defect
The performance index of the test is not greater than the specified range. 7.5.3 Minor defect
It is not caused by external factors and does not affect the performance of the instrument. 7.5 Type inspection Type inspection is a series of complete tests for the selected products of this model. 7.6.1 Purpose of inspection To determine whether the manufacturer is capable of producing products that meet the requirements of this standard. Type inspection is carried out under the following conditions: 1) The new product is finalized: 2) There are major changes in the design, process, materials and core components; 3) The serial production is more than 4 production units; 4) When the net full inspection is carried out for the production, 7.6.2 Inspection items All items listed in the table shall be inspected. 7.6.3 Sampling 7.6.3.1 Group A inspection Two instruments are randomly selected for Group A inspection.

QX/T 19—2003
No flat defects are allowed in Group A-C inspection, but three minor defects are allowed. When minor defects occur, they should be eliminated and the qualified products should be sent to the next inspection. After the Group A inspection, the company will make adjustments before the inspection is completed. 7.7 Factory inspection
Each device in the factory should be inspected by the inspection department before delivery to determine whether it meets the requirements of the product standards. 7.7.1 Group A inspection
