A fault simulation system 1 for evaluating the performance of multiÂchannel intermittent fault detection (IFD) test equipment 6 comprises a circuit 4 that creates defined resistance changes of varying characteristics to simulate real-world intermittent faults experienced by electrical/electronic equipment. The system is connected to the IFD tester under evaluation by an interface adapter 5 and to a computing device 2 which hosts intermittent fault simulation software. The software controls switches in the system to switch in or out different resistors, producing changes in resistance on an output channel. This simulates a continuity fault which is detected by the IFD tester if it is operating correctly. Pseudo-random variations of resistance with time or user-defined fault simulation sequences may be produced, saved, run and repeated by the system. |
