SELECTION PARAMETERS DESCRIPTION
Analog Output RANGE SETUP
(continued) (Source set to Dual Rng O

)
Xfer Fnct Log
Lin
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 O
2
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.
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 O
2
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
0.000% O

- 25.00% O
2
Enters the switching point between the High and Nor-
mal Ranges. O
2
values above this point will use the
High Range and values below this point will use the
Normal Range. The O
2
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

Low End
0.000% O

- 25.00% O
2
Enter the upper and lower analog output range values
for High Operating Range. The High End value defines
the measured O
2
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 5-12 of Table 5-5.)
