3.2 Operational Specifications

3.2.1 Scaling of Analog Outputs Channel #1 and Channel #2

Function
Linear oxygen
Very Low Oxygen
Average oxygen
Logarithmic oxygen
Reducing oxygen
Oxygen deficiency
Auxiliary TC Temperature
Combustibles
Burner efficiency
No Output
** For Logarithmic Oxygen scaling see the appendices in the 1732 Technical Manual
Output Channel 2 is independently isolated and separately scaled with the same options as analog Output
Channel 1.
For configurations in which one oxygen probe is used both channels transmit Oxygen process variables
based on that probe. For configurations with two oxygen probes Channel 1 outputs process variables
related to oxygen probe 1 and Channel 2 outputs process variables related to probe 2.

3.2.2 Local Display of Process Variables

Process Variable
Probe 1/2 Oxygen
Average Oxygen
Probe 1/2 Temperature
Probe 1/2 EMF
Probe 1/2 Impedance
Aux Thermocouple Temperature
Ambient Temperature
Ambient Relative Humidity
Max Theoretical Dry CO
Combustibles
Burner Efficiency
*Oxygen display units automatically default to % range above 10,000ppm (1%)
The oxygen deficiency output can be used in the same way as a combustibles analyser to signal the extent
of reducing conditions of combustion processes.
