园图电子电位差计的主要技术指标之一—示值基本误差与仪表的测量桥路有着密切的关系,在现场由于腐蚀性气体的侵蚀与温度波动较大等种种原因,天长日久,测量桥路电阻的阻值将发生变化,严重者将导致桥路电阻的引线从焊接部发生霉断,使仪表不能正常工作。这个问题一方面要求我们加强仪表的维护保养工作,同时掌握仪表的调校、测量桥路部分的故障分析及故障排除也是必要的。
Park map electronic potentiometer one of the main technical indicators - the basic error of indication and instrument measuring bridge is closely related to the scene due to erosion of corrosive gases and temperature fluctuations and other large, long time to measure the bridge The resistance of the resistance will change, in severe cases will lead to bridge resistance leads mold from the welding Department mold, so that the instrument does not work. On the one hand, this issue requires us to strengthen the instrument maintenance work, at the same time master the instrument calibration, measuring the bridge part of the failure analysis and troubleshooting is also necessary.
