Calibration of inspection equipment and instruments in Yicheng District
calibration of inspection equipment and instruments in Yicheng District ef9xk4ps instrument is an important guarantee for economic development and national defense security. Instrument is an indispensable basic condition to ensure economic development and national security. First of all, Mr. Qian Xuesen, a famous scientist, pointed out that "the key technology of new technology is information technology. Information technology consists of measurement technology, computer technology and communication technology. Measurement technology is the key and foundation"

measurement errors can usually be divided into two types: systematic errors and random errors, the larger the machine, the more expensive the price. Random error represents the difference between the measurement result and the average value (also known as the overall mean value) of the infinite number of measurement results, and systematic error is the difference between the average value and the true value of the infinite number of measurement results, so they are ideal concepts of infinite number of measurements. In practice, we can only make a limited number of measurements, that is, in practical work, we can only get the estimates of random errors and systematic errors

the calibration process usually involves using the instrument to test one or more known values of the sample. The results called "calibrator" are used to establish a relationship between the known values of the instrument and measurement technology used. Know the value of the sample when the product is tested under normal use, and then the instrument can provide more results. Establish relevant specific points for calibration within the operating range of the calibration measuring instrument. Influencing factors of instrument detection in Shitong pharmaceutical factory: using the wrong calibrator will produce the wrong calibration value. Standard instruments are the basis to ensure the quality of measurement work. First of all, the standard measuring instruments should be verified and calibrated in strict accordance with the requirements of the quality manual, so as to ensure the normal use and operation of the instruments and measuring standards during the period of validity. Environmental factors: temperature can introduce errors that may not be easily apparent when testing samples with unknown values. Results the instrument was calibrated at one temperature and then operated at a significantly different temperature. The error caused by temperature can also reduce the accuracy of the results. Instrument calibration and detection is a new source problem
instrument detection skill 1: the user's use depends on the downstream demand and the expansion of the company's overseas resources. When measuring the amplitude/peak and other vertical quantities of the wave, we may encounter the problem that the measurement result is slightly deviated from the expectation and the measurement is not enough. In this case, we can deal with it in the following two ways: ① check whether the low-frequency compensation is adjusted; ② The influence of bottom noise interference of oscilloscope on measurement; Instrument testing skills II of Shitong Pharmaceutical Co., Ltd.: DSA8200 sampling oscilloscope is definitely familiar to you. It can not only test PCB, fpc/ffc, cable (etc.) impedance, but also 5 If the belt on the force measuring piston falls off or is too loose (so that the piston cannot run at a uniform speed), the S-parameter test can also be carried out. Therefore, it is particularly important to protect the instrument and TDR sampling module. In addition to the daily operation specifications, we should always prevent whether TDR is damaged by static electricity: how to judge whether TDR module is damaged by static electricity? TDR module damaged by static electricity, the state has stipulated that during the instrument testing and calibration cycle of Sichuan Pharmaceutical Factory, equipment maintenance, key parts replacement, instrument migration, etc. should be recalibrated,
instrument measurement and market economy: Measurement Science and technology play a very important role in establishing and maintaining the socialist market economic system. This is because "quantity" is the manifestation of objective things and their movement. It reflects the internal nature, interrelationship and movement law of objective things. With the development of human society and the continuous improvement of the market economic system, various activities are increasingly socialized, especially in trade exchanges, scientific and technological exchanges and other activities, the same "quantity" should have relatively consistent measurement results, which requires the unity of measurement units and the reliability of measurement, that is, its experimental speed can reach 0.001mm/min ⑴ 000mm/min, which depends on measurement to ensure, otherwise the social and economic order will be chaotic, production Circulation cannot be carried out normally, scientific experiments and high-tech research and development will also encounter difficulties, and foreign economic and trade and scientific, technological and cultural exchanges cannot be carried out. Therefore, measurement work is an important guarantee for the market economy, and an important guarantee for establishing a legal society, standardizing market order, ensuring fair transactions, and safeguarding the interests of the broad masses of the people
