摘要
电子仪表在进行计量的时候常常会受到一些因素影响,从而造成结果出现一定的偏差,造成这样误差的原因复杂且多,无法完全排除这些误差的影响,因此,在电学计量过程中,只能通过科学的检定与校准尽可能减少不必要误差的干扰。本文详细归纳了电学计量中产生误差的主要因素,以便帮助工作人员清晰了解电学计量系统,尽可能在使用、校检过程中减少系统误差;本文进一步解释了在电学计量校准中的不确定度理论、特点和适用性,为减少电学计量误差、提高工作准确率提供了理论依据,让电学计量更加准确、科学,使之为科学技术发展贡献更大的力量。
Electronic instruments are often affected by some factors when measuring,resulting in a certain deviation of the results.The causes of such errors are complex and numerous,and the influence of these errors can not be completely eliminated.Therefore,in the process of electrical measurement,we can only reduce the interference of unnecessary errors as far as possible through scientific verification and calibration.The paper summarizes the main factors of error in electrical measurement in detail,so as to help staff understand the electrical measurement system clearly and reduce the system error in the process of use and calibration as much as possible.The paper further explains the uncertainty theory,characteristics and applicability in electrical measurement calibration,which provides a theoretical basis for reducing electrical measurement error and improving work accuracy,make electrical measurement more accurate and scientific,and contribute more to the development of science and technology.
