	Prompt	Range/Selections	Definition
DISPLAY TUNING			Select this to display the actual tuning trend with PV and
	TREND		setpoint (Figure 7-2). Data collection for this trend display
			will continue as long as the display shows either the trend or
			the Loop Tuning Menu. Use this display to help find the
			optimal tuning parameters.
			Note: If you access this display through a loop display (by
			Tabbing to and selecting the loop tag name at the top of any
			loop display), the trend data is not buffered when you leave
			and return to this tuning trend display. Therefore, if you wish
			to adjust tuning parameters and then look at the trend to see
			the effects, it is recommended you select Tune Loop through
			the Online menu, not through a loop display.
