在实际工作中,经常会遇到配热电偶的动圈仪表(以下简称仪表)和所配接的一次仪表(热电偶)分度号不符或测量范围不符,以及仪表示值超差等现象,所有这些,一般都要改变仪表的串联电阻(也称量程电阻)R_S的阻值大小以达到改制、调修的目的,使仪表正常工作。一般参考资料都介绍仪表量程改制时串联电阻R_S采用实验方法确定和计算法确定,其
In actual work, often encounter moving coil with thermocouple instrument (hereinafter referred to as the instrument) and the associated instrument (thermocouple) indexing number does not match or measuring range does not match, All of these, generally have to change the meter series resistance (also known as range resistance) R_S size of the resistance in order to achieve restructuring, the purpose of repair, the instrument work properly. General reference materials are introduced when the instrument scale conversion series resistance R_S determined by experimental methods and calculations to determine its
