编辑同志:在日常检测工作中,有不少厂矿同行们问及“为什么检定低准确度三表不出据更正值”的问题,为此我写了回答短文,谈谈个人初浅体会,请批评指教。我们知道,当标准表用作检定低准确度仪的标准时,其工作过程(指检定示值误差的过程,下同)和在被检时的工作过程相同时,可以使用更正值。而低准确度工作用仪表(又称工业仪表),用在工业电路或其它一般工作电路中时,与被检时的工作状态不同,所以不能
Editorial comrades: In the daily testing work, many factories and mine colleagues asked “Why test low accuracy of the three not according to the correction value” problem, for which I wrote a reply essay, talk about the personal experience, Please criticize advice. We know that when a standard meter is used as a standard for testing a low-accuracy instrument, a correction value can be used when the working process (the process of checking the indication error) is the same as the working process of the test. The low-precision work with the instrument (also known as industrial instrumentation), used in industrial circuits or other general working circuit, and was seized when the working state is different, so can not
