摘　　要：针对使用中出现的三线制温度数显仪接线不当带来的显示不准确问题 ,对显示仪的内部线路进行理论分析 ,并结合实验 ,提出在长距离接线 (导线阻值不能忽略 )时三线制的最佳连接方法。The paper is emphasized on the problem to the inaccuracy of temperature readout, which is caused by the improper connection to resistance probe. Analyzing inner circuit of the instrument in theory and combining with experiment, the paper put forward the optimum connection of three-line-system at long distance (not ignoring the cable resistance) and some using advice.
