OCS test equipment

Electronic crane scale electronic crane scale test equipment measurement and verification test electronic crane scale should be based on national verification procedures People's Republic of China JJG539-1997 "digital indicating scale" prescribed test procedures, for examination in the following order take photos. (A) visual inspection in accordance with JJG539-1997 "digital indicating scale" test procedures appearance requirements, visual inspection of the electronic crane, meet the requirements for qualified, otherwise unqualified. Electronic Hanging measurement and verification before (b) measurement of performance measurement of performance verification test, should pre-load to the maximum capacity or the maximum safe load. Zero Test (1) do not have the zero-tracking device or automatic zero-scale crane placed first zero, showing the value from zero to a sub-zero standard weight value added (0.1e) then measured sum and in accordance with the formula to calculate the error at zero error. (2) scale with zero tracking and automatic zero-setting device, first shown automatically adjusted to a value other than zero and zero tracking range, such as 10 e Placing load weights, to find flicker point, zero error is calculated according to a zero error. Zero error requires no more than 0.25e. Measurement OCS is the technical foundation of production development, technological progress and social life. In the social production of advanced metering technology required as a guarantee. From the selection of raw materials to feed quota, from process to product quality inspection, we are inseparable from the measure. A machine or electronic equipment, there are thousands of parts, components and lines form, if there is no corresponding measurement test instrument provides accurate and reliable measurement data, it is not assembled together. Machinery, chemical industry, metallurgy, light industry, textile and other factories and enterprises in the production process if not equipped with range of measuring instruments, equipment can not guarantee continuous, automated production, improve product quality can not view, can not guarantee safety in production, nor You may save raw materials and energy. The importance of high technology in the measurement test is particularly prominent. Like communications satellites, and other complex engineering, scientific and technical fields related to broad, requiring the measurement side of the test parameters, high precision, large measuring range, bandwidth, and can adapt to special and harsh environment, such as when you want to carry out high-precision measurements, lateral speed, distance and angle measurement, measuring dynamic pressure, dynamic temperature, low noise temperature, pulsating flow, vibration, shock, ultra-high temperature, cryogenic, newspaper force, low-thrust, high attenuation, low voltage, and nuclear radiation. This is not only to study the testing methods and equipment, but also to establish appropriate measurement standards, in order to ensure a variety of components, subsystems and overall system reliability. Relations metering and social life very closely. Such as providing accurate time standards, so that people's normal routines and participate in social activities and access to public transportation, communication time. As for the family daily use of a clock, water meter, gas meter, thermometer, thermometers, electronic scales, household appliances, various parameters, etc., must be accurate verification, in order to ease of use. Medical measuring instruments used to be accurate and reliable, in order to help medical personnel proper diagnosis and treatment. Air, water, pollution, noise, electromagnetic waves, weather and disaster forecasting public environment, it must be equipped with sensitive measuring and testing instruments. Described above, any science today, in any sector, industry and any activities need to be metered. As talk of "science and technology to develop, measure must first row." "Science and technology development today, we can say, no metering, unable to move." The level of measurement, has become an important symbol of a country's technological level.
