The accuracy of general electronic weightless scales is 5g, while the accuracy of weaker general electronic scales will be lower, and the precision of high-precision electronic scales is higher. Electronic scales are widely used in manipulation, seasoning, and measurement verification. The system software precision of electronic scales is usually very high. Among them, one of the key reasons that harm the precision of system software is the discrete system problem of electronic scales. The article starts from practice. The perspectives of activities and applications mainly indicate the key reasons for the deviation of the discrete system and the processing methods. Units, companies, agencies and institutions should be used as electronic scales for metrological verification standards, and their electronic scales used for foreign trade transactions, security, medical services, and environmental monitoring must undergo metrological verification to meet the standards before they can be applied. Those who fail to apply for metrological verification as required or fail to pass the metrological verification shall not be applied. The electronic weightlessness scale of the loader is based on two liquid level sensors respectively installed on the oil inlet and oil return channels of the hydraulic cylinder of the loading mobile arm to measure the change of the working pressure of the hydraulic cylinder during the whole process of the lifting of the loading mobile arm. And to adjust the speed, the microprocessor in the dashboard of the car will automatically carry out the measurement, and then calculate the net weight data information, and display the calculated net weight on the dashboard screen. The accuracy level of the electronic weight-loss scale of the loader should exceed the regulations of Y(b) scale according to the declaration of the manufacturing enterprise. The factory nameplate, face plate or table of the loader electronic weight-loss scale should be marked with the metrological verification law mark and the metrological verification mark, and the label, serial number and indication must be clear and identifiable, strong and reliable. Know the partners, culture and education, the number of opinions heard by the insiders: 30707 the number of likes: 300517 In 2010, he graduated from Anhui University of Technology majoring in fiber materials and engineering, and obtained a science and engineering degree certificate. According to the national metrological verification standard, the electronic scale belongs to the scale of medium accuracy level. The mark III is also called a three-level scale. The accuracy of the scale is defined as: accuracy level III, measurement verification division value e, measurement verification sub-myopia degree n, weighing Maix, small weighing Min. That is, the accuracy specification of the electronic scale is composed of various measurement verification index values. For example, the measurement verification sub-myopia of the three-level scale must be within the measurement range of 2000-10000. The higher the accuracy, the higher the measurement and verification characteristics of the scale, which means that the scale that people often say is very accurate and the deviation is small. In fact, the deviation of the electronic scale is checked by several key points of the allowable deviation. For example, an electronic scale weighing 3KG, the measurement verification score is 3000, the measurement verification division value is 1g, and the small scale is 20 It is stipulated that this scale cannot exceed the allowable error at 20 grams, 500 grams, 1000 grams, and 3000 grams, and the electronic weighing is regarded as reaching the standard when the measurement verification of each point reaches the standard. There are also many new inspection items when measuring and verifying electronic scales in the country's authorized metrological verification organization, such as the appearance inspection of electronic scales, anti-interference signal inspection, metrological verification label verification inspection, and auxiliary function inspection. Scales are subject to the national compulsory control of metrological verification. New scales purchased must not be applied until the local metrological verification unit meets the standards, and an annual review must be carried out every year. Only scales that meet the required measurement verification can be regarded as accurate scales.
