Select the transfer function used on the analog output. Selecting Log will not effect the output when Efficiency is selected as the Source.

Enter the upper and lower analog output range values for Normal Operating Range. The High End value de- fines the measured O2 value corresponding to the high analog output value, i.e, 20mA or 10V, and the Low End value corresponds to the low analog output value, i.e., 0mA, 4mA, or 0V.

Forces the output to the Normal Range.

Allows the IFT to select either the High Range or the Normal Range based on the present O2 value and the Mode Setup Values.

Forces the output to the High Range.

Selecting Yes will cause the High Range to be used whenever the probe is being calibrated.

Enters the switching point between the High and Nor- 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.

Enter the upper and lower analog output range values for High Operating Range. The High End value defines the measured O2 value corresponding to the high analog output value, i.e., 20mA or 10V, and the Low End value corresponds to the low analog output value, i.e., 0mA, 4mA, or 0V.

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