RaPID Control Feature

The RaPID (Response - assisted PID) feature offers dramatic improvements in control quality compared with conventional PID techniques. It responds much more effectively than PID techniques to load conditions. With this feature, the instrument's response at start-up, during setpoint changes and during disturbances shows considerably reduced overshoot and much more shorter settling times (see below).
