The setpoint value support points have a distance between each other of 5 % of the established set­
point value signal range. From the support points, the user-defined process valve characteristic curve is
generated by connecting 20 line segments (è Fig. 32). The user-defined process valve characteristics
curve is activated with the parameter CHARACTE in the menu CONFIG.(è Section 7.6.6).
