SUB-MENU
SELECTION	PARAMETERS			DESCRIPTION
Analog Output	RANGE SETUP
(continued)	(Source set to Dual Rng O2)
	Xfer Fnct	Log		Select the transfer function used on the analog output.
		Lin		Selecting Log will not effect the output when Efficiency
				is selected as the Source.
	Normal Range Values			Enter the upper and lower analog output range values
	High End			for Normal Operating Range. The High End value de-
				fines the measured O2 value corresponding to the high
	0.000% O2 - 25.00% O2
				analog output value, i.e, 20mA or 10V, and the Low
	Low End
				End value corresponds to the low analog output value,
	0.000% O2 - 25.00% O2
				i.e., 0mA, 4mA, or 0V.
	Dual Range Setup
	Mode Setup
	Range Mode		Normal	Forces the output to the Normal Range.
			Auto	Allows the IFT to select either the High Range or the
				Normal Range based on the present O2 value and the
				Mode Setup Values.
			High	Forces the output to the High Range.
	High in Cal		Yes/No	Selecting Yes will cause the High Range to be used
				whenever the probe is being calibrated.
	Switches at			Enters the switching point between the High and Nor-
	0.000% O2 - 25.00% O2			mal Ranges. O2 values above this point will use the
				High Range and values below this point will use the
				Normal Range. The O2 value must be below the switch
				point by 10% (of the "Switches at" value) to cause a
				switch from High to Normal Range.
	High Range Values			Enter the upper and lower analog output range values
	High End			for High Operating Range. The High End value defines
	0.000% O2 - 25.00% O2			the measured O2 value corresponding to the high
				analog output value, i.e., 20mA or 10V, and the Low
	Low End
				End value corresponds to the low analog output value,
	0.000% O2 - 25.00% O2
				i.e., 0mA, 4mA, or 0V.

NOTE: Relay output can be initiated upon range change. (See page 5-12 of Table 5-5.)
