Note: Sections 3.5.8. to 3.5.10. only apply when AO2 ASGN=TEMP.
3.5.8. AO2 Unit of Measure [AO2 UM]
The temperature unit of measure of AO2.
[Menu path: SETTINGS >↓ ANALOG OUT >↓ AO2 UM]
Default: F (°F) [C (°C)]
Optional Settings: None
3.5.9. AO2 Minimum Scale Reading [AO2 MS]
The temperature that results in an output signal of 0%.
[Menu path: SETTINGS >↓ ANALOG OUT >↓ AO2 MS]
Default: -20 (°F) [-30 (°C)]
Optional Settings: -50 to 160 (°F) [-50 to 70 (°C)]
AO2 MS cannot exceed AO2 FS.
3.5.10. AO2 Full Scale Reading [AO2 FS]
The temperature that results in an output signal of 100%.
[Menu path: SETTINGS >↓ ANALOG OUT >↓ AO2 FS]
Default: 160 (°F) [70 (°C)]
Optional Settings: -50 to 160 (°F) [-50 to 70 (°C)]
AO2 FS cannot be less than AO2 MS.
The output signal is linear to temperature.
Some B.A.S. application controllers use “span” rather than minimum- and full-scales. The span is
equal to the full-scale – minimum scale and the offset is equal to the minimum scale.
EBTRON temperature measurement accuracy is a fixed value. Decreasing the full scale does not
improve measurement accuracy. Today’s application controllers generally have sufficient accuracy
and input resolution to use the default output scaling of the transmitters.
Note: Sections 3.5.11. to 3.5.13. only apply when AO2 ASGN=AF2, F1-2 or F2-1
3.5.11. AO2 Unit of Measure [AO2 UM]
The airflow unit of measure of AO2.
[Menu path: SETTINGS >↓ ANALOG OUT >↓ AO2 UM]
Default: FPM [m/s]
Optional Settings: CFM [L/s]
The area parameter(s) [AREA] of -F and -U probe types must be entered (i.e. not equal to the factory
default value of {null}) for the LCD UM=CFM [L/s] option to be available. “ENTER AREA <OK>” will
be displayed when CFM [L/s] is selected. Press ENT or ESC to return to the “*AO2 UM=FPM [L/s]”
menu prompt.
