AUXOUT	DE	DEVIATION (Process Variable minus Setpoint)—
(continued)		Represents –100 % to +100 % of the selected PV span in
		engineering units. FOR EXAMPLE:
		Type “T” Thermocouple
		PV range = –300 °F to +700 °F
		PV span =	1000 °F
		Deviation range = –1000 °F to +1000 °F
		If PV =	500 °F
		and SP =	650 °F
		then Deviation Display =	–150 °F
		Auxiliary Output =	42.5 %
		NOTE: A deviation of 0°F yields an auxiliary output of
		50 %.
4mA VA	Low Scale Value within the	AUXILIARY OUTPUT LOW SCALING FACTOR—Use a
	range of the selected variable	value in engineering units for all selections above except
	to represent 4 mA	Output.
	[factory setting = 0]	Use value in percent (%) for Output. (Output can be
		between –5 % and +105 %.)
20mA V	High Scale Value within the	AUXILIARY OUTPUT HIGH SCALING FACTOR—Use a
	range of the selected variable	value in engineering units for all selections above except
	to represent 20 mA	Output.
	[factory setting = 100]	Use a value in percent (%) for Output. (Output can be
		between –5 % and +105 %.)
		*When Deviation is selected, only one operating
		parameter will be entered. This value represents the
		deviation level that will produce 20 mA output. Zero
		deviation will produce a center scale (12 mA) output. A
		negative deviation equal in magnitude to the Auxiliary
		Output High Value will provide a low end (4 mA) output.
