(1) The non-legality of calibration is the voluntary traceability of an enterprise; the verification has a legal nature and is a law enforcement activity in the field of measurement management.
(2) The calibration mainly determines the indication error of the measuring instrument; the verification is a comprehensive evaluation of its measurement characteristics and technical requirements.
(3) The calibration is based on the calibration specifications and calibration methods. Usually, it should be stipulated in a unified way, and sometimes it can be set up on its own; the basis for the verification is the verification procedure.
(4) The calibration usually does not determine whether the measuring instrument is qualified or not. If necessary, it can determine whether a certain performance meets the expected requirements; the verification must be concluded whether the measurement is qualified or not.
(5) The calibration result is usually a calibration certificate or a calibration report; the verification result is a qualified certification certificate, and a failure notice is issued.
Verification: In JJF1001-1998, “Verification†is defined as: the process of ascertaining and confirming whether a measuring instrument complies with statutory requirements, which includes inspection, marking and/or issuing a verification certificate. Verification is usually an important measure to carry out quantitative transmission and ensure accurate and consistent quantities.
Weight maintenance:
1, stainless steel weight maintenance: Stainless steel weight will not rust, but due to long-term use, in the calibration and maintenance of electronic scales will wear, and at the bottom of the weight or there will be a screw that can be screwed down The inside is empty. After the weight is worn out, the quality will be reduced. At this time we need to calibrate the weight. We must find an electronic scale with an accuracy level greater than the weight to calibrate it and calibrate it. Slowly add metal particles to the weight until the calibration is complete.
2, cast iron weight maintenance: cast iron weight is iron, there will be a lot of attention in the use of the place, we must pay attention to the moisture side of the weight rust, long-term use will make the paint off due to wear, so easy to For rust, we must clean the rust on the surface of the weights frequently, and at the same time, we must find a weigher whose accuracy level is greater than the weight level to calibrate them. Otherwise, when we use these rusted weights to repair electronic scales, it will lead to maintenance. The appearance of electronic scales is inaccurate.
