24、0欧姆）3. 测得两个阻值相同，或者接近的一端就是公共端。（注：公共端除外的另外两根线的阻值是0，实际测量中大概是0.04欧）怎样用万用表测量pt100热电阻可以先在回路中断开PT100接线，然后用万用表的电阻档（200）测量其电阻值。但测量结果只能判断PT100好坏，不能作为验证其精度的依据。 PT100在0时阻值为100，随着温度的升高阻值逐渐增大，具体的对应关系可以查看其分度表一度对应0.385欧。这就是铂电阻温度系数 TCR = 3850 ppm/K，说的就是这个意思，也就是说，温度变化一摄氏度，电阻变化0.3850欧，当然，这是理想状态下哦.例如：114查分度表对应36，（114-100）/0.385=36.3 反之36.3*0.385+100=114。-
