The trending feature allows to visualize and to monitor gradual changes in your forming process 
such as a steady but slow rise or fall of the forming load. Trending can be activated individually for 
each channel. 

Graphic trend display with Stop/Go

The SK bbx offers graphic trending on it's color display. The presentation includes the display of the 
average forces over time, the selected trend limits, and any machine stops in between. The trending 
screens can be accessed as follows:

1)  Press the M function key, then select Trend (press key 1), or

2)  From the single force curve screen, press the Cursor-key to go to the trending screen for the 
     same sensor channel.
