笔者针对电子汽车衡数字乱跳现象查找方法和故障原因作一总结。例1:一台电子汽车衡仪表数字乱跳,负增升不断上升。经检查,接线盒是新更换的,里面没有积水和水蒸气,在检查接线盒时发现仪表显示Err-01,而且此现象时有时无,不动时就有数字负增升跳跃。经仔细检查发现,有一根传感器的线缆断接过且放在地上(此秤为有基坑),分析为该接线处没有处理好,有雨 The author of electronic truck scale digital jump phenomenon to find ways and causes of failure to make a summary. Example 1: An electronic truck scale digital jumped, the negative increase continues to rise. After inspection, the junction box is a new replacement, there is no water and water vapor, check the junction box found Err-01 instrument shows, and this phenomenon sometimes no, when there is no fixed number of digital negative jump. After careful examination found that there is a sensor cable off and on the ground (this scale is a foundation pit), analysis of the wiring is not handled properly, rain
