A Single Chip Microcomputer Controlled Cable Fault Tester

Traditional cable fault testers, some manufacturers call them cable fault detectors or cable fault detectors, are actually the same type of instrument, and their general composition is:
① Traditional form: It adopts a separate form of flash tester, path tester, and fixed point tester. The general packaging method is as follows: the cable fault flashover tester is packed separately, and the cable fault locator, cable path detection signal source, and other accessories are packed in one box, namely two boxes and three pieces. Due to the high frequency of use of flash testers and fixed-point testers during fault testing, and the low frequency of use of path testers, the independent configuration of the three components has its rationality, clear functional decomposition, simple structure, and convenient maintenance and use.
② Adopting a combination of flash tester and path tester, and independent configuration of fixed-point tester. This configuration is usually a two box two piece configuration, with the same functionality as the first configuration. Its advantage is the absence of one component, which can be said to be convenient to use to some extent. Its disadvantage is that due to the use of high-power devices in the signal source of the path analyzer, its frequency of use is not high. Therefore, this configuration increases the complexity of the flash tester, increases its failure rate, and makes maintenance relatively complex.
