目前,国内市场中的网线测试仪大多采用接触式测量法,特别是网(缆)线束的测量比较繁琐,效率不高。还有一些采用非接触式的测量仪,这种测量仪利用感应式方式只是查找线束中的某根网线,但是无法确定该网线中8根信号线其中哪一根线断点,故常称为“寻线仪”。本项目所述感应式网(缆)线精测仪在使用中不需要连接一根网线的两端(只需在一端通入信号,感应端检测),不仅能确定故障网(缆)线,而且能确定网(缆)线中具体某一根线及断点的位置,并用LED显示故障,提高网线的检测效率和精度。
At present, most of the network cable testers in the domestic market use the contact measurement method. In particular, the measurement of the wire harness is relatively complicated and inefficient. Some use non-contact measuring instrument, the measuring instrument using inductive method is to find only one of the wire harnesses, but can not determine which of the eight signal lines in the network break, so often called “Finding line”. In this project, the inductive mesh (wire) line precision measuring instrument does not need to be connected with two ends of a network cable (only the signal is input at one end and the inductive end detection), which can not only determine the fault network cable, But also to determine the network (cable) in a specific line and breakpoint location, and LED display fault, improve the detection efficiency and accuracy of network cable.
