, otherwise there is short trouble in phenomenon；When carrying out open circuit fault detection, the wiring in a manner described of all core one end, the other end
All it is shorted together, then sends test signal successively by binding post order, and detect from machine array (2) terminals simultaneously
The corresponding signal detection end of son, if each road correspondence can detect low level signal, illustrates that all cores do not exist open circuit event
Barrier, if the test side that a certain route core connects terminal corresponding can not detect low level signal, then illustrates this route core open circuit.
