Method and apparatus for verifying connectivity of an instrumentation system

摘要

An instrumentation system including a plurality of sensors attached to a test piece, each of the sensors provided with an electrical signal generating device and an electrical signal measurement device. Each sensor is located remotely from its electrical signal measurement device, and connected thereto by connectors. A method of testing connectivity of the instrumentation system including: inducing an electrical signal in a first sensor; and checking that the electric signal is received in the corresponding signal measurement device.
