Abstract
Systems and methods for testing a valve using valve signatures are provided. An analytical device receives a first valve signature from a portable measurement device. The portable measurement device obtains the first valve signature by causing a plurality of control signals to be applied to the valve and receiving data representing actual positions of the valve corresponding to the applied control signals. The analytical device may generate an image including a graphical representation of the first valve signature and a second valve signature that was measured prior to or after the first valve signature.
