Metrology Support the role of engineering in the model

8 years 28 No. 5 with a table, but the actual point of view, 6 half of the table has been fully able to meet the current on-site Calibration traceability requirements. But the formation of an 8-bit semi-digital multimeter testing devices cost about six half-DMM 4.3 times the cost of verification device, 8-bit half of the table test costs are much higher than the 6 half of the calibration of the test fee. Accounts for similar problems in the evaluation of equipment more than 40% of all indicators. It can be seen on the economic impact measurement. Security work for the type 5 metering data and decision-making body of work based on the results of measurement of security models for decision-making body, the Senate research units and the use of units and equipment products, test equipment, test and calibration of measuring the status and data protection. This will help decision-making bodies and the General Division units to detect problems in the process of model development. Measurement test equipment sector through participation in the assessment, development of performance indicators for testing accuracy, the standard equipment, traceable to national defense for the follow-up to the highest standards of equipment, provide technical support, and provides engineering test and calibration data to determine the author models decision-making bodies. In short,[link widoczny dla zalogowanych], the model project is a complicated systematic project, the project only in the models do a good job at all stages of a comprehensive measurement of the full assurance in order to effectively guarantee the quality of model projects,[link widoczny dla zalogowanych], progress.

Defense technology base, 2007, (11) :2-9. (Continued from page 59) but this method in laboratory conditions require the hardware is relatively high, so using this method in the laboratory will be subject to their own capacity constraints, this method is generally applicable to relatively large or high equipment performance laboratory. Compared to the first method,[link widoczny dla zalogowanych], the second, the use of three methods is relatively wide, but still subject to their own devices laboratory conditions, such methods for small and medium or the same type and level of equipment with accuracy more laboratories. During the verification of laboratory standard equipment is the fourth most commonly used method, this method is not very high hardware requirements of the laboratory, there is a relatively stable as long as the verification standard can be measured at any time verify the equipment, but it will save to send higher authorities verify the additional costs, so this method is suitable for most small laboratories. 2.6 kg instance to M-class group of weight during the verification example. Methods: The stability of the verification standard measurement approach to a set number 2125 for the verification of standard weights, group weights in kilograms to the M level measured on a test or calibration of the institutions for verification, select the verification standard (No. a set of weights for the 2125) and the weight of 1kg, with its M-class weight kg group were measured to obtain measurement results Y. : 10.0000013 (Unit: kg), separated by six months after the group again with the M-class weight in kilograms of weight in the group of 1kg of weight measurement, the measurement results Y. = 1.000003 (Unit: kg), M-class kilogram weight of the permissible error limit set port = 50mg, the JY a YoI = 1.7mg ≤ ・,[link widoczny dla zalogowanych],,,, n = 81.5mg, consistent with the principle of verification methods to determine, shows the performance of the device is stable and reliable state, thus ensuring that accurate and reliable measurement results issued. 3 Conclusion of laboratory equipment, measurement standards during the implementation of verification is to ensure that laboratory test / calibration results of the quality of an important means to ensure the credibility and assurance laboratory test / calibration data is an important part of accurate and reliable,[link widoczny dla zalogowanych], but also the importance of quality control for laboratory way. Through the period of verification, and can find between the term operation of standard equipment anomalies and take corrective measures in a timely manner, thus avoiding the performance of the equipment caused by changes in the value transfer is the phenomenon of unreliable data, to ensure that the calibration equipment performance is steady and reliable state.
