What you can do on the Trend Tab
Use the Trend tab (see Figure 29) to observe real time valve performance. These process trend
graphs are useful for troubleshooting a control valve and for tuning the PID positioning
parameters. The graphs can be manipulated only on the Y axis.
You can detach the trend as a separate window for viewing while performing calibration and
diagnostic tasks. To detach the trend:
Right click in any tab select Detach Trend.
In Manual or Setup mode, drag the position indicator to change the valve position.
