Extended Actuator Signature 

The extended actuator signature test is run over a user-specified range of valve travel.  To obtain an
extended actuator signature go to the diagnostics screen, select Act Signature in the Type list box, enter
values in the Start Position and End Position boxes, and choose a value between 1 and 9 in Speed and,
click the Extended button to begin test.  The test result is presented in the Diagnostic Graph window.

A step response of valve position can be used to examine the dynamic characteristics of a valve sys-
tem.  The step response test is run over the user-specified range of valve travel. ValVue produces a
Position vs. Time graph after the test.  A step response appears in Diagnostic Graph window as illustrat-
ed in figure 23 above with a step change from 50 to 60% of valve travel.
