Abstract
A system and method for verifying the performance and health of wire systems and end devices, including instruments and processes. A computer runs software that collects data from sampled sensors, stores the data, screens the data for outliers, analyzes the data, performs in situ testing, and generates results of the analysis and testing. The system and method verifies not only the steady state performance of instruments, but also the dynamic performance of instruments and the transient behavior of the processes. In one embodiment, the system performs testing of the wiring system connecting the end devices located at the process. In another embodiment, the system also performs analysis of the amplitude probability density and a power spectral density determined from the sensor, or end device, data. In still another embodiment, the system performs a time domain reflectometry (TDR) analysis for a wiring system connecting an end device.
