PURPOSE:To display the connection inferiority of a connector and the disconnection of load separately, by a method wherein the electrical connection and the non-connection of each wiring are detected and it is decided whether all wirings passing a same connector are electrically connected or not. CONSTITUTION:At first, decision is performed with respect to the electrically non-conductive state of all wirings l1-l4 related to a connector A and, when all data from check ports C1-C4 are L, H is outputted to an outlet port P10 while a transistor Tr10 is turned on to drive LEDD2 and the connection inferior state of either one of connectors is displayed by this operation. On the other hand, when either one of each data read in from ports C1-C4 is L, H is outputted to an outlet port P9 while Tr9 is turned on to drive LEDD1 and the predetermined display of disconnection is carried out by this operation. At the completion time of decision related to the connector A, the decision related to a connector B is similarily performed. |
