PROBLEM TO BE SOLVED: To provide a system and a method for testing a valve by using a valve signature.SOLUTION: An analytical device 22 receives a first valve signature from a portable measurement device 24. The measurement device 24 supplies a plurality of control signals to a valve 104, and receives data representing an actual position of the valve corresponding to those control signals to obtain the first valve signature. The analytical device 22 generates an image including a graphical representation of the first valve signature and a second valve signature measured prior to or after the first valve signature.SELECTED DRAWING: Figure 1 |
