ProofCheck incorporates all elements of proper SIS testing in a single solution, including field devices, wiring, signal conditioners, safety logic, BPCS logic, final control element response, and manually entered data. The entire procedure is captured electronically and displays pictures, manuals, and any information the user needs to perform the tests. All information is captured in a database and displayed in built-in reports.
