Fault Isolation Capability

In the case of a failure, the test aids in fault isolation by reporting the possible cause(s) of failure. The fault isolation capability varies depending on the nature of the fault and the system configuration. enatest can detect and isolate hard faults. The following table shows the fault isolation capability for different configurations. A Yes indicates that fault isolation capability is available for that component in that configuration and a No indicates lack of fault isolation capability for that component in that configuration.
