Abstract

PURPOSE:To decrease checking time and to improve the reliability and efficiency of wiring of home bus by connecting a checking device to an information receptacle to check the open state, connecting an auxiliary checking device short- circuiting terminals to other information receptacle so as to check the continuity between terminals. CONSTITUTION:When a checking device connects to a home bus and a start SW is depressed while an auxiliary checking device is not connected, a current flows to terminals of an 8-pin modular connector 11 for twisted pair cable to check no current flows to other terminals. Then the absence of short-circuit in all twisted pair cable is checked automatically while selecting terminals to which current flows in this way and a short-circuit location is displayed on an operation display section 16. Then the auxiliary checking device connects to an information receptacle of other twisted pair cable and a continuity check start SW is depressed. The current flows from the checking device to terminals to detect return of the current through the auxiliary checking device.

In this way, after testing that the twisted pair cable is not short-circuited, connect the auxiliary testing device to the information outlet of the other twisted pair cable, press the continuity test star) SW, and apply current to terminal 1 while leaving the test ga on. It is detected that the current returns to terminal 2 through the auxiliary testing device. If the twisted pair cable between the testing device and the information outlet connected to the auxiliary testing device is connected correctly, the current will return. In addition, if the wire is not connected, no current will be returned, so the operation/display section 16 will display that the oven is connected between pan 1 and 2. Next, current will be passed from the inspection device to terminal 3, and an auxiliary inspection will be carried out. Check that current returns through the device to end f4. By repeating the test by switching the terminals through which current flows in this way, it is possible to test that all the twisted pair cables between the information outlet connected to the testing device and the auxiliary testing device are correctly connected.
