In \"harness testing,\" cables, harnesses, and other tested items are examined to determine whether they meet electrical standards.<\/p>\r\n<\/br>\r\n<\/br>\r\n<\/br>\r\n<h3>Five Items of Harness Testing<\/h3>\r\n<p>\r\nHarness testing is divided into five different categories. \r\nTest items are determined and selected as needed. By correctly understanding each test item and determining the criteria, it is possible to efficiently conduct high-quality and optimal testing.\r\nThe following is an explanation of each test item.<\/p>\r\n<div class=\"c-spacer--s\">\r\n<h4>Wiring Testing<\/h4>\r\n<p>\r\nIn harness testing, wiring testing, continuity testing, and open short testing are synonymous. \r\nIn wiring testing, the test target is compared to the wiring of a good cable and checked for short\/open\/miswires\/excess circuits.\r\nAll testing terminals are scanned and checked in a short time.\r\nSet an appropriate value for the wiring judgment value that serves as the threshold value.\r\n<\/p>\r\n<\/br>\r\n\r\n<!--\r\n<a
